LM12UU-OP Linear Motion Ball Bearings for Robot 12*21*30
Product Description:
Metal linear bearing is a linear motion system produced at low cost for use with a cylindrical shaft with an infinite stroke. Since the bearing ball is in point contact with the shaft, the load is small. The steel ball rotates with very little frictional resistance, so that high-precision and smooth motion can be obtained.
Linear Motion Bearings consists of an outer cylinder, ball retainer, balls and two end rings. It has high precision and rigidity, ease of assembly, and ease of replacement.
Application of linear bearing:
- Linear Bearing is widely used in precision equipments, like electronic equipment, tension tester, etc.
- Linear Bearing is also widely used in automatic cutting machine, printer, card sorting machine, etc.
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.
