30*40*30 Metal Sleeve Bearing Steel Sleeve

Main types of bushings
1. Sliding bearing liner (dry/oil-free)
Made of self-lubricating materials (such as graphite copper sleeve, engineering plastic POM, PTFE), it does not require external lubricating oil and has good wear resistance.
Door and window hinges, agricultural machinery, food machinery, and situations where refueling is not possible.
2. Rolled lining
Made of rolled steel plates with oil grooves, lightweight, and low cost.
Light load support for general machinery, such as conveyor rollers.
3. Ball joint bushing/spherical bearing
The inner ring is a spherical structure that can swing within a certain angle to compensate for centering errors. Very common in truck/car suspension systems.
Truck/car suspension control arm, steering rod ball joint, allowing the wheels to bounce up and down and turn.
4. Hydraulic liner
The interior is filled with oil, which attenuates and absorbs vibrations through the flow of oil between the internal chambers. Advanced suspension components.
The engine mount and subframe connection points of luxury cars/trucks provide excellent vibration reduction and sound insulation effects.
5. Rubber lining
Made of a metal jacket and vulcanized internal rubber, utilizing the elasticity of rubber to reduce vibration, noise, and allow for small deformations.
Almost all suspension connection points of vehicles, such as stabilizer bar linkages, spring bushings, and mechanical equipment bases.
6. Olisai liner
A special type of metal rubber liner, formed by vulcanization of metal wire mesh, can not only reduce vibration but also withstand high and low temperatures, used in extreme environments.
Aircraft engines, high-performance racing cars.
