CC CC CC3.Slide bearingsSlide bearingsPrefaceSlide bearings absorb the journals of axises or screws.We distinguish between radial bearings to transduce/absorb transverse forces and axial bearings to absorblongitudinal forces. Moreover, there are guide bearingswhich merely guide the screw in its position withoutabsorbing any definable forces.The journals rotate inside the bearing bushes subject tosliding friction with oil, grease, water or even withoutlubrication (i.e. in dry runs).3.1.Slide bearings made from plasticsContentsMaterialoverviewIn general, our slide bearings run smoother than antifrictionbearings and are also indifferent to edge pressure,impacts and vibrations, owing to the big contact surfaceof the slide bearings (between screw and slide bearingbushes) and its high polymer damping properties. Slidebearings do not require any sealings, for they are indifferentto dirt.Slide bearings are simply constructed and can also beproduced separately (ill. 9) without any difficulties.Running on pure liquid friction, they achieve an almostunlimited working life and are able to run with highestscrew speed.In general, they are cheaper than anti-friction bearings.3.1.1.Slide bearing materialsWe supply all slide bearing bushes itemized in thiscatalogue only made from plastics of the Wolf-ZEDEXseries- see chapter 2-.3.1.2.Slide bearing shape and dimensionsThe dimensions of the slide bearings made from plastics,which are offered in this brochure, correspond to thefollowing DIN-standards.This is to make sure, thatmetallic slide bearings according to DIN can be replacedby those made from plastics, without alterating thedimensions and tolerances of the connecting parts.- DIN 1850solid bushings used to insert into casings- DIN 1552used to press on journals- DIN 1494rolled bushings used as stuffing bushings- DIN 1498considerably thick-walled compared to stuffingbushingsThe bushings are supplied according to standard withoutlubricating grooves, lubricating bags, oil drilling rigs andwithout slit.In case these additives are required, you should enquireseparately.Wolf Kunststoff-Gleitlager GmbH • Heisenbergstr. 63 - 65 • 50169 Kerpen-Türnich • Tel. 02237/9749-0 • Fax. 02237/9749-20Index Slide bearings Slide bearings Conditions ofTribologyMathematical Design(with collar) (cylindrical) installationexample guidelines11
