Linear Plain Bearing LM4UU 4mm Optical Axis
The ZLV Linear Plain Bearing LM4UU 4mm Optical Axis is an innovative product that provides smooth and precise linear motion. This bearing is built with a high degree of precision and is comprised of an outer cylinder, a series of steel balls, a ball retainer, and retaining rings at both ends.
The ball retainer is situated within the outer cylinder and is held in place by the retaining rings, allowing the steel balls to repetitively circulate on the raceway without falling out. The outer cylinder is heat-treated to attain sufficient hardness, ensuring safety and longevity during operation. The ball retainer is made from resin to reduce noise and wear between it and the steel balls. This linear bearing is suitable for usage within a temperature range up to 80℃.

Features and Advantages
- High Precision, High Rigidity, and Low Noise: The ZLV linear bearing has a high hardness outer cylinder and steel balls due to strict manufacturing requirements, resulting in high precision. The usage of high tensile strength resin retainers reduces the noise level.
- Easy Assembly: The bearing can withstand loads from any direction. The standardization and uniformity of the product, along with the ease of machining the associated components, make it simple to meet assembly requirements.
- Variety of Product Forms: ZLV offers standard type, clearance adjustment type, open type, extended type, and flange type linear bearings to cater to different design needs.
Applications
This linear bearing has been designed for a wide array of applications due to its superior features and benefits. These include:
- Corrosion and Rust Resistance: The bearing block and shaft support are made from aluminum alloy, which, after surface electroplating, not only looks aesthetically pleasing but also provides excellent corrosion resistance. The chromed hard shaft does not rust, providing outstanding rust prevention.
- Easy Assembly and Interchangeability: The bearing block is standardized and has strict precision requirements, making it easy to meet assembly or repair interchangeability requirements.
- Smooth Operation and Low Noise: SC, SME series contact the linear bearing and shaft sliding, resulting in minimal friction resistance. Hence, operation is extremely smooth and quiet.
- Economic Benefits: Lightweight, corrosion-resistant, interchangeable, and low-cost, these bearings can bring out the maximum performance in various machines, achieving maximum labor-saving and automation benefits. Compared to other types of rails, they have a lower cost and a competitive price advantage.
