High Load Capacity | Plain bearings can withstand substantial loads, making them suitable for demanding applications such as heavy equipment and construction machinery. |
Adaptability | Plain bearings can accommodate misalignment and shock loads, providing resilience in dynamic operating environments. |
Cost-Effective | Plain bearings are generally more affordable than other bearing types, offering a cost-effective solution for various applications. |
Industry | Applications |
---|---|
Automotive | Engine bearings, suspension components, pumps |
Aerospace | Landing gear, flight control systems, turbines |
Industrial | Conveyors, gearboxes, machine tools |
Power Generation | Turbines, generators, pumps |
Medical | Surgical instruments, prosthetics, implants |
Q: What is the difference between sleeve and flanged bearings?
A: Sleeve bearings have a cylindrical shape, while flanged bearings have a flange on one end to prevent axial movement.
Q: How do plain bearings handle misalignment?
A: Plain bearings can accommodate misalignment due to their conforming surfaces. However, excessive misalignment can reduce bearing life.
Q: What are the factors that affect the lifespan of plain bearings?
A: Load, speed, lubrication, temperature, and surface treatment all impact the lifespan of plain bearings. Proper maintenance can extend their service life.
