VIIPLUS rolled (wrapped) bushings is produced with diamond shaped lubrication indents on the bearing surface(s). These bushings are ideally suited for thin wall applications. The indents provide lubricant reservoirs that allow for excellent and prolonged service.
For applications that are sealed or difficult to maintain, we also manufacture this product with self-lubricating graphite filled diamond or circular indents.
They are light-weight and compact and are available as sleeve bushings, flange bearings, washers and plates. They are produced in both inch and metric sizes.

• Metric Flanges
Bronze rolling bearing, with tin bronze alloy CuSn8/ cusn6.5p as the material, the surface of the rolling diamond oil hole, plays the role of oil storage, it has good fatigue strength and bearing capacity, corrosion resistance, wear resistance.
Widely used in agricultural machinery, construction machinery, construction machinery and other high-load low-speed occasions.
(also called FB090)
1. Save a lot of copper material and time of copper sleeve manufacturing:
2. Light weight and low cost compared with axle sleeve and rolling bearing made by vehicle;
3. Various oil grooves can be processed on the friction surface, and oil holes can store certain grease, so that the time of oil filling is 5 times longer than that of copper sleeve;
4. Extremely high bearing capacity, especially suitable for rough friction surface;
5. High heat dissipation, small expansion coefficient, stable service condition and long service life.

it is a low-maintenance bronze sliding bearing. Primary lubrication is necessary. Oil or grease lubrication is possible. Due to lubrication pockets, clearances are reduced to a minimum.
