What is a Bearing?

Sleeve bearings (sometimes called bushings, journal bearings or plain bearings) facilitate linear movement between two parts.

Sleeve bearings consist of a metal, plastic or fiber-reinforced composite sleeves that reduce vibrations and noise by absorbing friction between two moving parts using a sliding motion.

Sleeve bearings advantages, including lower cost, less maintenance, greatly reduce noise at low speeds and easier installation.

Hydrostatic bearings fluid film bearings that rely on a film of oil or air to create a clearance between the moving and stationary elements.

Employs a positive pressure supply that maintains clearance between the rotating and stationary elements. With a hydrostatically-lubricated bearing, the lubrication is introduced under pressure between the moving surfaces.

Hydrostatic bearing spindles feature high stiffness and long bearing life, and are often used for fine machining and finishing.

Hydraulic bearings drive system is a quasi-hydrostatic drive or transmission system that uses pressurized hydraulic fluid to power hydraulic machinery.

Hydraulic bearings advantages, long lifetime, high stability, good lubrication effect ect.

Ball bearings is a type of bearing that contains a ball to maintain the clearance between the bearing races. The motion of the ball reduces the friction compared to flat surfaces sliding against each other.
The main function of the ball bearing is to support axial and radial loads and decrease rotational friction. It uses at least two races to support the ball and transfer the load through the ball.

Ball bearings advantages

1. The bearing uses grease with higher dripping point (195 degree)

2. Large operating range temperature ( -40 ~ 180 degree)

3. Better sealing shield to prevent leaking of lubricant and avoid foreign.

4. particles entering the casing

5. Easy bearing replacement.

6. Increase motor performance (less motor friction)

7. Bearing is easy available in the market.

8. Less precaution during assembly

9. Cheaper cost for replacement

Magnetic bearing is a type of bearing that uses a magnetic force to support machinery parts without having any actual contact with the part itself while the machine is turned on.

The magnetic force is strong enough that it lifts the small piece of the machine and allows it to move while it is suspended in the air.

This eliminates the friction between the piece and the machine itself.

No friction, no limits: magnetic bearings not only increase service life, they also enable oil-free operation in a vacuum at maximum speeds. allows to reach 500,000 RPM and more.
