Description

Wrapped bushing, bronze, filled graphite lubrication pockets, maintenance-free

The diamond-shaped lubrication pockets are filled with graphite, a solid lubricant.The dimensions of viiplus® bronze graphite thin walled bearings are according to DIN 1494 / ISO 3547.

STRUCTURE AND COMPOSITION

Bronze Bearings and Bronze Sleeve Bushings made of CuSn8 ROHS are filled with graphite

MICROSECTION

CuSn8 with
composition
Sn 8 %
P < 0.05 %
Cu Rest

Bronze Bearing material made of solid bronze strip with indents for lubrication,Material Bronze (CuSn8).Bearing forms available in standard dimensions.
Industry Standards/Compliant Restriction of Hazardous Substances (RoHS) Compliant.

During the installation, grease must be filled in the lubricating chamber on the sliding surface. Lubrication during operation can extend service life.Plain bearing bushing can also provide lubrication slots and holes.The length of the standard bushing can be shortened.We also roll the bushing according to the size you define.

Bronze Bearings Application

Bronze bearing for agricultural machinery, brakes and certain construction machinery.

The plain bearing bushing is made to DIN ISO 3547.092 bronze bushing is based on bronze CUSN8 and evenly distributed drilling oil hole on its sliding surface. When in assembly, oil or grease should be stored in the holes before bushing is sealed form both ends. 092 bronze CuSn8 material has the advantage of abundant oil storage, easy-to-assembly ,machine the compactness etc. It can replace the conventional whole copper middle load, low speed such as in convey machine, hoisting machine, windlass, aligning machine etc.
