For higher requirements – e.g. higher temperature ranges – different materials are available in this category.
Bronze is a versatile and commonly used material because it is available in many alloys and compositions. Bronze bushings (also called bronze bearings or solid bronze bushings) are tough and robust, unlike softer brass bushings. The bronze bushings have a long life and resist shocks, knocks, wear and corrosion. They require an external lubricant, such as grease or oil, during installation and during operation to reduce friction and wear.

Specially Manufacturing Bushings
The manufacturing process starts with cutting the sheet to the correct rectangular shape. Then the plate will be rolled and calibrated to the final size and finished with chamfering the edges.
Range Of Application
Agriculture machinery, truck cranes & construction machinery, suitable for impact loads
Tolerances
Bushings are manufactured according to DIN 1494/ ISO 3574 with standard sizes for H7 housing tolerances and f7 or h8 shaft tolerances.
Request:
It is used in conditions of increased load, but low speed, for example, on agricultural, construction and engineering vehicles.
It is widely used in hoisting machines, construction machines, automobiles, tractors, trucks, machine tools and some mineral engines.
