Wrapped Bronze Bushes



These bearings are wrapped from a cold formed homogenous bronze (CuSn8), which can achieve exceptional material properties. According to various lubrication conditions, we can provide diamond shaped lubrication indents (grease) and incorporate holes (oil), these designs can rapidly build up a lubrication film at the start of movement and thereafter reduce the running friction.

Properties

Economic solution for bronze bearing application due to a thin wall thickness. High load capability and good stability with low abrasion. Suitable for rough working conditions, good corrosion resistance.

Range of application

Agriculture machinery, truck cranes & construction machinery, suitable for impact loads

Maintenance

It is 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, it 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.

The bearings are 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
