These bearing shells are wrapped in cold pressed uniform bronze (CuSn8), which can achieve exceptional material properties. According to different lubrication conditions, we can provide diamond-shaped lubricating recesses (lubrication) and include holes (oil), these designs can quickly create a lubricating film at the beginning of movement and, therefore, reduce friction during movement.

VIIPLUS specialized in research and development, production and sale of self-lubricating bearings. The main Bronze Wrapped Plain Bearings products are metallic polymer composite bearings, bimetallic composite bearings, bronze coated bearings, self-lubricating monometallic bearings and other bearings.
090 is made from high quality alloyed, hot rolled phosphorus tin bronze. The plain bearings are specially designed for high loads and are shockproof. The entire sliding surface of the bearing consists of lubrication pockets that form a lubricating film that reduces friction both at start up and during operation. FB090 is intended for radial, oscillating and axial movements and is particularly suitable for medium to high loads.

090 bronze bearing, using special formula of high density copper alloy strip as the substrate, the surface can be rolled according to user requirements rhomboid or hemispherical oil hole, oil groove. It has the advantages of high density, large bearing capacity, good wear resistance and long service life, etc., which can replace the traditional casting copper sleeve, reduce the mechanical volume and reduce the cost.
It has been widely used in lifting machinery, construction machinery, automobile and tractor chassis, machine tool industry and mining machinery, but also can be made into bearing bush, flanged bushing, thrust gasket and ball bowl and other forms.

To the H9 tolerance of the slide bearing we recommend shafts with tolerance e7 or f7. If h-shafts are used, the bearing inner diameter should be machined up to tolerance F7.
The bearings are wrapped in a homogeneous cold stamped bronze (CuSn8) with exceptional material properties. Standard sizes have diamond-shaped lubrication recesses in the bearing surface. These indentations serve as lubricant reservoirs to quickly create a lubrication film at the beginning of the movement and subsequently reduce running friction. The material is suitable for building applications and agricultural machines.

Depending on the lubrication conditions, we can provide diamond-shaped lubricating pins (grease) and include holes (oil), a self-lubricating cylindrical bushing with a thin-walled bronze bushing, coated with CuSn8, with a bronze support and a cylindrical bushing, which can quickly build up a lubricating film . movement, and then reduce working friction.
The thin wall design is made by rolling, which can meet the requirements of low precision and cost sensitive occasions. Rhomboid oil hole design for grease lubrication, through the initial lubrication quickly establish oil film to reduce adhesive wear, the inner hole can be processed according to the need, the copper alloy substrate has a good corrosion resistance and thermal conductivity. Regular oil feeding is recommended for medium and low load conditions.
