CAMROL Cam Follower BearingsCAMROL — The Industry StandardIn 1937, McGill engineers invented the first needle bearing cam follower. Since that time, McGill has maintained itsleading position through the continuous development of new features and improvements to the CAMROL bearingproduct line.As today’s leading manufacturer of quality cam follower bearings, McGill has developed many features to extendbearing life for a variety of operating conditions, lubrication requirements and application environments. McGilloffers the broadest range of cam follower bearings on the market with over 1,400 standard designs to choose from.OverviewThe typical functions of a cam follower are to provide anti-friction support of linear movement or to follow thesurface of a cam. The CAMROL cam follower from McGill was designed to withstand the intermittent shock, loadingand precision requirements associated with these applications.Track or LoadSupport RollerExternal CamLoadMotionIndustries Auto plants Food and beverage Forest products Oil drilling Printing Steel mills Textiles4Applications Automation equipment Machine tools Packaging equipment Unit material handling

Heavy-Duty Metric CAMROLThis series provides greater dynamic load ratings by using cylindrical rollers in place of standard needle rollers. Thisconstruction allows the bearings to support radial loading, as well as some axial loading.MCFD SeriesLabyrinth Type SealingTwo-Rows of Cylindrical RollersFull complement design, engineered forhigher dynamic load rating.Annular Lubrication GrooveThe groove provides acircumferential pathto direct lubricantto the oil hole.Large GreaseReservoirAs compared to afull complementneedle bearing.Black Oxide FinishCAMROL bearings have a blackoxide finish on all externalsurfaces to help inhibit corrosion.MCYRD SeriesYoke type Heavy-Duty Metric CAMROL bearings aredesigned for yoke (straddle) mounting on a shaft.For part nomenclature, see page 19.7
OPTIONSCAMROL Cam Follower BearingsLUBRI-DISC Seal OptionThe LUBRI-DISC seal option increases bearing life up to 10 timeslonger than unsealed bearings: Labyrinth and contact sealing help protect against loss oflubrication and help prevent entrance of contaminantswhile providing low drag operation. Vents help prevent seal blow-out during relubrication. Integral backplate design reduces internal friction byeliminating metal-on-metal contact. Less friction lowersthe operating temperature, which extends grease life andallows for higher operating speeds.Note: The LUBRI-DISC seal is rated up to 250 F maximum.Hex Hole Option for Ease of InstallationThe hex hole option reduces costs by speedinginstallation or removal of stud type cam followers.During typical installation or removal, the bearingmust be held in place while torque is applied to themounting nuts. The optional hex hole increasessecure holding power over the standard screwdriverslot in the face of the bearing. The hex hole option isstandard for stud type Heavy-Duty, Special-Duty andCorrosion-Resistant (CRES) CAMROL bearings and isan option for standard CAMROL bearings.The hex hole option is ideal for: Difficult to reach assemblies Blind hole mounting Equipment with many bearingsNote: The hex hole option does not allow for relubricationfrom the roller end of the bearing on most sizes. (All metricversions and inch sizes below 3" OD.)8
Crowned OD Option for Long LifeA slight crown on the OD of a cam follower bearing can increase bearing life up to three times longer than the standard,cylindrical OD bearing. The crown helps more evenly distribute stresses for the following conditions: Heavy loading Misalignment of track or housing Turntable or rotary camsNote: The crowned O.D. is an option for standard CAMROL and Heavy-Duty CAMROL bearings.Cylindrical OD:Misalignment can cause corner loadingComputer analysisshows crowned ODcan increase lifethree times longer.Finite element analysis of camfollowers under heavy loadsshows crowned OD increasesL10 life.

SPECIAL-DUTYCAMROL Cam Follower BearingsSpecial-Duty CAMROL for Tough EnvironmentsSelect Special-Duty CAMROL bearings for tough applications such as automotive production, metal formingassembly and welding environments.Heavy Walled Outer RaceThrough hardened to resist wear.Jam Nuts IncludedSimplifies installation process.Precision Needle Rollers with CageHelps prevent roller skewing and allows for higherspeeds.End Plug SealHelps seal out contamination and seals in greaseat the roller end.Black Oxide FinishCAMROL bearings have a black oxide finish on all external surfaces tohelp inhibit corrosion.Resists ContaminationSpecial-Duty CAMROL bearings are specifically designed to resist contaminated environments. A metal end plugseal on the roller face helps block out contamination and resists welding spatter.Maintenance FreeSpecial-Duty CAMROL bearings extend bearing life up to six times without lubrication maintenance by usingsynthetic grease and caged needle rollers. Caged needle rollers allow for a larger grease reservoir than standardneedle bearing cam followers, a beneficial feature when relubrication is not possible.10
Improved ProtectionOn the stud side of the Special-Duty CAMROL bearing, the LUBRI-DISC seal offers improved protection overstandard sealing.The LUBRI-DISC sealBUSHING TYPECAMROL Cam Follower BearingsEliminates RelubricationThis bearing series eliminates the need forlubrication by utilizing a non-metallic bushinginstead of needle rollers. Save relubricationtime and inconvenience. This is ideal whenrelubrication is not desired and greasecontamination must be avoided.The bushing type is appropriate for: Light loads and slow speeds Not for food applicationsNon-metallic BushingFor part nomenclature, see page 19.11
HEAVY-DUTYCAMROL Cam Follower BearingsHeavy-Duty CAMROLfor Incidental Thrust ApplicationsWhile standard needle bearing cam followers are the economical choice for most applications, incidental thrustloads make Heavy-Duty CAMROL bearings a better choice. Primary causes of incidental thrust are misalignmentof housing or track, high loading causing stud deflection and rotary tracks or cams. Heavy-Duty CAMROL bearingsemploy a unique internal construction, consisting of two rows of cylindrical rollers designed to manage much of thethrust.Resists ContaminationRubber lip seals are standard in Heavy-Duty CAMROL bearings. Although standard cam followers do well in mostconditions, the rubber lip seals in Heavy-Duty CAMROL bearings increase protection against contamination.Maintenance FreeStandard bearing has no relubrication feature. Seals are pointed inward for improved grease retention. The largelubricant reservoir and rubber lip seals keep more grease in the bearing for maintenance free operation.Rubber Lip SealsDouble Rows of Cylindrical RollersFull complement design engineered forhigher dynamic load rating.Black Oxide FinishCAMROL bearings havea black oxide finish on allexternal surfaces to helpinhibit corrosion.Large Lubricant ReservoirIntegral FlangeTogether with end plate design, and propermounting, helps provide non-separable assembly.12
CRESCAMROL Cam Follower BearingsCorrosion-ResistantCAMROL for Food andBeverage ApplicationsGreater Corrosion ResistanceWhether equipment is exposed to the elements or to extremewashdown in food and beverage applications, the corrosion-resistant(CRES) CAMROL bearing series extends bearing life in wet or corrosiveenvironments. The CRES CAMROL features 400 series stainless steel tohelp prevent corrosion.Standard cam followers rust quickly.FDA Compliant GreaseCRES CAMROL bearings utilize H1 FDA compliant grease for foodapplications.Tested per ASTM B117 salt fog test, 5%saline solution, 100 F, 100% humidity.Improved SealingThe LUBRI-DISC seal provides up tofive times better protection againstwashdown than standard seals. This sealis featured in CRES CAMROL bearings 1"OD and larger.In a test originally performed to meetexacting aerospace standards, CRESCamrol bearings were tested with a highpressure spray aimed at the bearing face.This graph shows how each seal held-up– the Lubri-Disc seal featured in CRESCamrol bearings was the obvious winner.For part nomenclature, see page 19.13
TRAKROL Cam Follower BearingsTRAKROL Bearings for Thrust and ContaminationTRAKROL bearings feature a different design than CAMROL bearings to allow for heavier thrust loads. Smaller sizes( 3" OD or point diameter) use ball bearing inserts and larger sizes use tapered roller bearings to accept thrust loads.Superior WearHeavy walled outer housinghardened to resist wear or fracture.Rubber Lip SealSpecial SealingMetal expansion plug providesextra sealing at roller face.Resists ContaminationRubber lip seals help keep out contamination on the stud side of the bearing and a metal end plug seal helps protectthe roller face.Thrust ApplicationsTapered roller bearing or ball bearing inserts allow for the heavier thrust capabilities of the TRAKROL bearing.Maintenance FreeA large grease reservoir allows for longer life without relubrication.14

A History of Innovation.a Future in Helping You Stay CompetitivePrecision ManufacturingBecause there are no industry-wide standards for tolerances on cam follower bearings, McGill has set its owndemanding tolerances for CAMROL bearings. McGill uses statistical process control to help provide cam followersthat are manufactured according to these exacting standards.McGill was one of the first bearing manufacturers to receive ISO 9001 certification. ISO certification and the processit encompasses help McGill design and manufacture bearings to uniform quality standards. While others have triedto imitate the McGill design, only McGill has the precision, quality and performance that leads the industry.Advanced ToolsMcGill engineers use a wide variety of tools,such as computer analysis and sophisticatedlaboratory testing, to anticipate and designnew solutions.As applications push the limits of bearingperformance, McGill engineers analyzeand help prevent problems through failureanalysis. Physical analysis, including scanningelectron microscopy and internal and thirdparty testing facilities, are available to helpunderstand and diagnose problems, leadingto cost effective solutions.16
