Gleitlager CuSn8
Discover our plain bearings: Flange bearings, sleeve bushings, and thrust washers. Customizable bushing materials available. Our products are wear-resistant, maintenance-free, and designed to withstand dirt, dust, and corrosion.
CuSn8 Wrapped sliding bearings, Bronze Bearings made of CuSn8 gleitlager with Lubrication Indents. Metric Size Made to order: For Example Flange Bushing.E92F5050 E92F 4040MM.
From solid bronze materials
with diamond-shaped lubrication pockets or with perforations in accordance with ISO 3547/DIN 1494.Custom parts with plugged graphite available upon customer request.
The bronze wrapped bushings are wrapped of a cold formable homogenous bronze (CuSn8), which will obtain exceptional material properties. The standard size is fitted with diamond-shaped lubrication indents on the surface of the bearing. These indents serve as lubricant reservoirs to rapidly build up a lubrication film in the start movement and therewith reduce the start friction.

Main Factors that Influence the Service life of the Bushing
1).PV Value
PV value is an effective criterion to calculate the service life of TCB900/TCB902. If there is need to prolong the service Life, PV value must be reduced.
2).Environment Temperature
Service life of the TCB900/TCB902 will shorten in higer ambient temperature .
3).Roughness
Service life of TCB900/TCB902 can be greatly improved if its mating axis is made of chrome-plated stainless steel with hardness more than 50HRC and surface roughness among 0.4~0.63.Structure
The bearings are wrapped from a cold-formed homogenous bronze (CuSn8) with exceptional material properties. The standard sizes are fitted with diamond-shaped lubrication indents on the bearing surface. These indents serve as lubricant reservoirs to rapidly build up a lubrication film at the start of the movement and thereafter reduce the running friction. The material is suitable for construction and agricultural machinery applications.

CuSn8 bronze bushings Maintenance
CuSn8 bronze bushings has a low maintenance bushing material. An initial greasing during installation is necessary, after that periodic greasing with oil or grease is mandatory. The diamond pockets are an excellent lubrication depot and keeping maintenance to a minimum.
Bronze rolling bearing, tin bronze alloy CuSn8as the material, the surface rolling rhombic oil hole, since the role of storage grease, CuSn8 bronze bushings has good fatigue strength and load-carrying capacity, corrosion resistance, wear resistance. Widely used in agricultural machinery, construction machinery, construction machinery and other high-load low-speed occasions.
