– Key Features
• Gothic Arch Groove Configuration — Absorbs vertical shock loads and distributes forces evenly for extended component life
• Ball Retainer System (S1) — Retaining piece prevents ball scattering, ensures uniform nut load distribution, and enhances durability under moment loads
• High Load Capacity & Rigidity — Engineered for significant loads with super-high capacity options available for short-stroke, high-load applications
• K1 Maintenance-Free Lubrication — Integrated lubrication unit delivers long-term efficiency without scheduled relubrication; maximum operating temperature 50°C (122°F)
• Compact Design — Low-profile options with space-saving dimensions for integrated positioning systems
• Corrosion-Resistant Options — Stainless steel construction for light-load and corrosive-environment applications
• Standard Grease Fitting — M5 × 0.8 port; A1 seal design optimizes grease retention and minimizes splattering
– Typical Applications
Precision linear positioning in machine tools, automation equipment, and test systems requiring repeatable accuracy with minimal maintenance.
– Compatibility & Integration
Part of NSK’s broader linear guide ecosystem, including LH15 and LW17 series offerings for modular system design.
