Heavy Load Ball Spline LBST15 Ball Spline Bearing LBST20 LBST80 Ball Spline Manufacturer

High rigidity and high load：Three rolling protrusions are evenly distributed around the outer circumference of the spline at a 120 ° angle, each of which is clamped by two rows of steel balls on the left and right sides. Pre pressure is applied through a single flower key nut to eliminate rotational clearance, greatly improving rigidity.

Zero clearance high precision: The preloading structure achieves zero clearance in the rotation direction, ensuring high positioning accuracy.

Multi directional load capacity: It can simultaneously withstand radial and axial loads and moments, with outstanding resistance to cantilever loads.

High speed stability: The retainer design prevents steel balls from falling off, and the optimized lubrication structure supports high-speed movement and rotation.

Compact and space saving: Single axis can replace traditional dual parallel axis design, simplifying mechanical layout.

Heavy duty machinery: engineering equipment cantilever structure, large stamping machine transmission system.

High torque space: Compact robot joints, precision machine tool rotating table.

Special environment: Optional metal retainer model (temperature resistance of 100 ℃), suitable for high temperature working conditions.
