Description

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.

Typical Applications

  1. The product’s inside the surface is full of diamond oil indention, which can stock grease.
  2. Minim oil lubrication can be applied in the water-lubrication environment
  3. Good anti-abrasion, low coefficient of friction, long operating life.
  4. Can work consecutively at 100℃~+200℃.
  5. Good mending, low-noise, non-pollution
  6. This wall, light, can reduce the volume of the machine
  7. High density, high load no alveoli
  8. The products now are applied in different machines, such as auto machines, pumps, plastic injection machines, auto industry, heavy equipment, etc.

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.

CuSn8 bronze bushings wrapped from a cold formed homogenous bronze (CuSn8) with exceptional material properties. The standard sizes are formed with diamond shaped lubrication indents in the bearing surface. The indents serve as lubricant reservoirs to rapidly build up a lubrication film at the start of movement and thereafter reduce the running friction. These materials are suitable for construction and agricultural machinery applications.

The bearing is wrapped of a cold form able homogenous bronze , which will obtain exceptional material properties. The standard bearing is fitted with diamond shaped lubrication indents on the bearing surface. These indents serve  as  lubricant reservoirs  to  rapidly build  up  a lubrication  film  in the start movement and there with reduce the start friction. Typical application:widely  applied  in hoisting  machines  and other  construction  machines, automobiles, tractor, trucks,  machines tools and some mineral engines
