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 gap between the shaft and the ball is -3~+8μm (reference value), which can achieve rolling motion with very small gap.
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 it can obtain higher torque rigidity and moment rigidity.
It is widely used in CNC machine tools, industrial robots, automation equipment, semiconductor manufacturing and other fields, significantly improving the dynamic response and positioning accuracy of the system. It supports customized design (such as shaft diameter, lead, preload level) to meet diverse needs, and is the core transmission component of high-end mechatronic systems.
