CNC High-Precision Linear Bearing Block. High Rigidity and High Load Capacity: Four-row arc-groove structure with a 45 contact angle, capable of withstanding loads in four directions: radial, reverse radial, and left and right lateral. High-precision operation: Precision-ground raceways paired with carefully selected steel balls ensure micron-level straight-line tracking, making them suitable for precision positioning. Low Noise and Low Vibration: Optimised retainer design ensures smooth ball circulation, with operating noise below 60 dB. Long Service Life: High-quality bearing steel combined with precision heat treatment ensures a service life of over 50,000 km under rated dynamic loads. High Interchangeability: Manufactured strictly to industry standard dimensions, allowing direct interchangeability with standard guide rails of the same specifications. Self-lubricating option: Sliders feature built-in oil-retaining cotton or graphite lubrication blocks, enabling long-term maintenance-free operation.
