The sbr25 linear rail represents a high-accuracy, heavy-duty rolling guidance system tailored for automated equipment, CNC machines, semiconductor manufacturing, and other industries. With a four-row circular arc groove structure and 45° contact angle steel balls, it achieves omnidirectional high rigidity support, ensuring smooth motion and precise positioning under heavy loads. The rail is made of 45# steel with quenched and hardened surface treatment, offering excellent wear resistance for harsh industrial environments.
product highlights
High-Precision Positioning
Adopts C3 precision standard with repeatability accuracy up to ±2μm, meeting the needs of precision machining.
Automatic self-aligning design compensates for installation surface deviations to ensure motion stability.
Heavy Load Capacity
Four rows of symmetrically distributed steel balls provide a maximum dynamic load of 12kN and static load of 25kN, suitable for heavy-duty applications.
Capable of withstanding combined loads in all four directions, ideal for complex mechanical structures.
Low Friction & Longevity
Rolling friction coefficient as low as 0.0015 reduces energy consumption and supports high-speed operation (up to 60m/min).
Self-lubricating design minimizes maintenance, extending service life by over 5 times compared to traditional sliding guides.
Modular Desig
Sliders and rails feature standardized dimensions for interchangeability, enabling quick replacement and maintenance.
Multiple mounting options (e.g., top-locking, side-locking) adapt to various equipment requirements.
