Types - Range of retaining magnets / raw magnetsRetaining magnets / Raw magnets are simple problem solvers for no-wear fixings.Owing to their structure, these magnet systems have only one adhesion level. The magnets and iron poles are optimal arrangedsuch that the whole of the magnetic energy is focused on the adhesive surface.Retaining magnets4The spatial effect of the magnetic field is limited in shielded systems, with the effect that surrounding objects are not magnetised.Flat gripperØ d 6 . 125h 4.5 . 26Housing steel, zinc plated, red lacquered or stainless steelØ d 12 . 88h 6 . 8.5Housing steel, zinc plated, with rubber jacketRod gripperØ d 4 . 63h 10 . 65Housing steel, zinc plated or red lacqueredØ d 6 . 32h 20 . 40Sandwich configuration of the steel poles , housing brassELESA and GANTER models all rights reserved in accordance with the law.

Retaining magnets / Raw magnets - Materials of the magnetHard ferrite (HF)SrFe (Strontium ferrite)Magnets made of hard ferrite (80% iron oxide) are made by sintering process.Retaining magnets6Like all ceramic materials, these magnets are very hard and brittle and virtually non-machinable.The magnetic adhesive force drops when the magnet is heated.AlNiCo (AN)Aluminium nickel cobaltMagnets made of AlNiCo (main constituents include aluminium, nickel, cobalt and iron) are made by sintering or casting process.The material is very hard and tough, but can be redressed.These magnets are used in applications in which the magnetic field is to remain as static and stable as possible, alsounder higher temperature fluctuations.SmCo (SC)Samarium cobaltMagnets made of SmCo (main constituents include samarium and cobalt) are made by sintering process.The material is very hard and brittle and is virtually non-machinable.The magnetic adhesive force drops when the magnet is heated.NdFeB (ND)Neodymium iron boronMagnets made of NdFeB (main constituents include neodymium, iron and boron) are made by sintering process.The material is very hard and brittle and is virtually non-machinable.This material delivers ultimate magnetic holding power.The magnetic adhesive force drops when the magnet is heated.Materials of the magnet in comparisonDescriptionHard ferrite (HF) AlNiCo (AN)SmCo (SC)NdFeB (ND)Adhesive forcegoodmediumstrongvery strongMax. working temperature *) 200 C 450 C 200 C 80 CCorrosion resistancevery goodvery goodgoodless goodnot possiblediamond cutting,grindingnot possiblenot possiblemoderateeasyvery difficultdifficultby demagnetisingfieldsby demagnetisingfieldsonly by largedemagnetising fieldsonly by largedemagnetising fieldsvery reasonablehighvery highreasonableMachineabilityDemagnetisation capabilityPrice*) The max. temperature used is only a guide value because it also depends on the dimensions of the magnet.ELESA and GANTER models all rights reserved in accordance with the law.

Retaining magnets / Raw magnets - Adhesive forcesOther factors apart from the magnet material and the size of the magnet affecting the magneticadhesive force are:- an air gap (magnetically non-conductive materials act like an air gap)- the quality of the surface (roughness and shape)7- the temperatureThe magnetic adhesive force can also be impaired by alternating thermal stress and by chemical factors (aggressive baths,gases, etc.).The diagrams and graphs below show guide values relating to the impact on the magnetic adhesive force caused by differentmechanical specifications.The nominal magnetic adhesive forces shown in the tables of the standard pages are minimum values which are achieved at:- room temperature- perpendicular „tear-off“ under full surface contact of the magnet- workpieces made of low-carbon steel with a minimum thickness of 10 mmInfluence of the air gapInfluence of the material (Steel grade)100%technically pure iron86%C60, X6Cr1795%St37, C1584%42CrMo494%St44-2, X210CrW1290%C4550%20MnCr587%Ck4530%GGHardened workpieces are bad conductors of the magneticflux.

GN 54.1Retaining magnetsFeatures and applicationsRetaining magnets GN 54.1 are a shielded magnetic system.The configuration of magnetic and iron poles is known as sandwichmagnet system. These retaining magnets deliver ultimate holdingpower, also with smaller workpieces.Attachment options include pressing in or gluing in.1)k1 is the maximum dimension by which the retaining magnet can beshortened without losing its properties.2) Mounting these retaining magnets directly in steel components willcreate a magnetic short-circuit which reduces the retaining power byas much as 15 %. To avoid this effect, the spacings k2 between brassjacket and steel component should be observed. These spacings shouldalso be maintained if the retaining magnet is shortened.View on adhesive surfacek1dBrass housingIron poleshRetaining magnets24 SpecificationRod-shaped, smooth finish.Housing brass.
