Linear Plain Bearing LM25UU 25mm Optical Axis


The ZLV Linear Plain Bearing LM25UU 25mm Optical Axis is a high-precision, low-noise bearing component. It features an outer tube, ball bearings, and a resin retainer. With standard, clearance-adjustable, open, extended, and flanged options, it ensures smooth, efficient linear motion under 80°C.

Linear Plain Bearing LM25UU 25mm Optical Axis

The ZLV Linear Plain Bearing LM25UU 25mm Optical Axis is a top-quality component that forms part of the linear motion systems. It is made up of an outer tube, ball bearings, ball retainers, and securing rings at both ends. The retainer, fitted within the outer tube, is secured by the rings preventing the balls from dropping out of the track during the cyclic movement.

  • High Precision, Rigidity, and Low Noise: This linear bearing is made with high rigidity outer tubes and balls, which along with strict manufacturing standards, result in high precision. The use of a high tensile strength resin retainer further minimizes noise.
  • Easy Assembly: The ZLV linear bearing can withstand loads from any direction. Its standardization and specification allow for easy processing of complementary components, making assembly efficient and effective.
  • Product Variety: We produce various types of linear bearings including standard, clearance-adjustable, open, extended, and flanged bearings, catering to diverse design requirements of customers.

Linear Bearing Housing Features

  • Corrosion and Rust Resistance: The linear bearing housing and the shaft support seat are made of aluminium alloy and undergo electroplating after processing. This not only enhances the aesthetic appeal but also increases its resistance to corrosion. The chrome-plated shaft also has excellent rust prevention.
  • Easy Assembly and Interchangeability: The standardization and specification of our product, coupled with strict precision requirements, make assembly or repair interchangeability easy, meeting customer requirements.
  • Smooth Operation and Low Noise: The SC, SME series feature linear bearing and shaft contact sliding, resulting in extremely low friction resistance, ensuring smooth operation and low noise.
  • Cost-Effective: With its lightweight, corrosion resistance, interchangeability, and low cost, it offers an excellent performance to price ratio. When compared to other types of slide rails, it is more cost-effective, providing a competitive edge in pricing.
