Product Description

What is linear bearing? 

Metal linear bearing is a low-cost production of linear motion system for unlimited travel with the cylinder axis. Since the ball bearing point contact with the shaft, so use the load is small. Minimal friction ball rotation, thereby to obtain smooth movement precision. Plastic linear bearings are self-lubricating properties of a linear motion system, the biggest difference is that the metal in the metal linear bearings linear bearings are rolling friction, is the point contact between the bearing and the cylinder axis, so this suited for low load speed movement; while plastic linear bearings are sliding friction is between the bearing surface contact with the cylinder axis, so this low-speed movement for high loads.

Linear bearings are used in conjunction with hardened linear drive shaft. For infinite linear motion systems. Load the ball and quenching transmission shaft because it is the point contact, allowing the load is small, but linear motion, friction smallest, high precision, fast movement.


What's the feature of your linear ball bearings?

The linear ball bearing (also called ball bushing or shaft guiding) consists of a polymeric cage with raceway segments made of hardened steel to guide the ball sets within the complete system. Recirculating balls provide unlimited stroke at low friction movement.

1.Smooth movement,low friction,high rigidity and long life.

2.We can make non-standard linear bearing according to clients samples or drawings.

3.Prompt delivery and OEM service.

4.Nice appearance,complete product system.
