Linear ball bushings designed for compact, reliable linear motion in small-scale mechanisms. Key benefits Save space: Works with a guide shaft to deliver smooth linear motion in a compact footprint, ideal where space is limited. Corrosion resistance: Outer cylinder is available in steel or stainless steel to resist rust and extend service life in demanding environments. Low-noise and durability options: Retainer choices include stainless steel for harsh conditions or a low-noise resin for quieter operation. High interchangeability: Compatible with standard guide shafts and can be combined with shafts interchangeably, simplifying replacement and design flexibility. Features and performance Function: Provides guided linear motion with low friction and stable rolling contact. Compatibility: Designed to operate together with standard guide shafts; suitable for small-scale mechanism design and equipment requiring precise linear movement. Materials: Outer cylinder in steel or stainless steel; retainer in stainless steel or low-noise resin depending on operating requirements. Performance: Reduces installation footprint, resists corrosion, and offers quiet operation when using the resin retainer option. Practical applications Compact automation and pick-and-place systems where equipment space is limited and reliable, repeatable motion is required. Laboratory and medical devices that need corrosion-resistant components and low-noise operation. Small machine tools, 3D printers, or precision fixtures where interchangeable linear bearings simplify maintenance and part replacement. Notes for selection and use Choose stainless steel outer cylinders and stainless retainers for harsh or corrosive environments. Choose low-noise resin retainers when quieter operation is a priority. Verify shaft diameter and tolerance compatibility to ensure proper fit and interchangeability with the guide shaft. This linear ball bushing solution provides space-efficient, corrosion-resistant, and interchangeable linear motion components for small-scale mechanism designs.
