Description
Self-Lubricating Linear Bronze Bushings (LM Series)
A standard LM and an extended LM-L oilless linear bronze bushing.
Upgrade your linear motion system with our LM Series Graphite Bronze Bushings—a high-performance, maintenance-free, drop-in replacement for conventional LM linear ball bearings. By replacing recirculating balls with a solid bronze body and embedded graphite lubricant, these oilless bearings deliver superior durability and reliability, especially in harsh operating conditions.
Eliminate the need for constant greasing and the risk of failure from contamination. Our self-lubricating linear bushings are designed to fit standard metric linear bearing blocks and housings, making them the perfect upgrade for applications in dusty, high-temperature, or wash-down environments.
Complete Linear Bearing Solutions
LM Series (Standard)
The standard length bushing is a direct replacement for the most common LM..UU type linear ball bearings. It provides a robust, general-purpose solution for a wide range of linear motion applications.
LM-L Series (Long Type)
The extended length “L” series offers a larger contact surface, resulting in significantly higher load capacity and improved stability. It is ideal for applications with heavy loads or large overhanging moments.
LM-OP Series (Open Type)
The open “OP” series is designed for use with fully supported shafts. The opening in the bushing allows it to pass over shaft support rails, preventing shaft deflection over long spans and ensuring maximum precision.
Key Advantages Over Ball Bearings
- Zero Maintenance: Self-lubricating design requires no grease or oil, ever.
- High Load Capacity: Solid bronze construction offers a much larger contact area, supporting significantly higher loads than ball bearings.
- Impervious to Contamination: No recirculating ball tracks to jam with dust, dirt, or debris.
- Silent, Smooth Operation: Glides silently along the shaft without the noise of rolling elements.
- Wide Temperature Range: Operates effectively in extreme heat or cold where grease would fail.
