SAMICK LINEAR BUSHING: Structure and Special Features
SAMICK Linear Bushings are precision components designed for low-friction, high-precision linear motion in industrial automation systems, widely used in packaging machinery, medical equipment, and office automation devices.
Core Structure
Polymer Retainer: Guides recirculating steel balls along a cylindrical raceway, minimizing ball-to-ball friction and ensuring smooth, quiet operation. Steel retainers are available for high-temperature or vacuum applications.
SUJ2 Steel Balls: Provide point contact with the shaft and outer sleeve, reducing friction to enable speeds up to 3m/s.
Hardened Outer Sleeve: Made of high-carbon chromium bearing steel, precision-ground after heat treatment for rigidity and dimensional stability. Corrosion-resistant options (nickel-plated, stainless steel) are available for harsh environments.
NBR Seals (Optional): Prevent contamination ingress and lubricant leakage, extending service life in dusty conditions.
Key Features
Full Interchangeability: Standardized dimensions allow free combination with matching LM shafts, eliminating the need for custom fitting.
Low Friction & Noise: Recirculating ball design converts sliding friction to rolling friction, resulting in smooth, stick-slip-free motion with minimal noise.
Enhanced Load & Life: Optimized ball distribution delivers 3x higher load capacity and 27x longer travel life compared to standard linear bushings.
Easy Installation: Flanged variants (e.g., LMK series) can be mounted directly without additional housings, simplifying equipment design.
Applications & Notes
Suitable for light-to-medium load linear motion systems, including packaging lines, medical devices, and office equipment. Not recommended for rotational loads or heavy shock/vibration environments without additional damping measures.
