Product Features:
Large load capacity: The rolling groove of the ball is precisely ground and formed, and the Gothic 40° angle contact is adopted. Due to the large contact angle, it has a large load capacity in both radial and torque directions.
Zero gap in the rotation direction: By adopting 2~4 rows of balls with a contact angle of 40°, the spline shaft and the spline outer cylinder are combined, and the gap in the rotation direction can be zero by adjusting the preload method.
The clearance between the shaft and the ball is -3~+8μm (reference value), which can achieve rolling motion with very small clearance.
High sensitivity: Due to the special design of the steel ball contact point, in addition to high rigidity, it is more sensitive and can reduce energy waste.
High rigidity: Due to the large contact angle, it has high rigidity, and appropriate preload can be applied according to the situation, so higher torque rigidity and moment rigidity can be obtained.
Simple assembly: Due to the special design, even if the spline outer cylinder is separated from the spline shaft, the steel ball will not fall off. Therefore, assembly, maintenance and inspection are easy to carry out.
