Linear Flange Bearing LMK20LUU
- LMK20LUU nickel-plated bearings are used in combination with linear guide shafts to achieve infinite linear motion through the rolling of steel balls.
- The balls roll along the track grooves formed by the housing and cage, enabling the bearing to achieve continuous linear motion relative to the guide shaft. This linear flange bearing LMK20LUU ensures stable operation and reliable performance in precision applications.
Compared with plain bearings, they provide low-friction, high-precision linear motion and are widely used in various fields such as handling equipment and semiconductor machinery.
Specifications
Low Friction: Rolling design reduces energy consumption.
High Precision:
Ideal for precise positioning (e.g., CNC machines).
Long Service Life:
Wear-resistant materials (e.g., bearing steel) and sealed construction.
Lightweight:
Aluminum models suit low-load applications.
Interchangeability:
Standardized dimensions (e.g., LM series) for easy replacement.
