NIPPON BEARINGS - SPR 40

Details

NB rotary ball spline, designated as SPR type. These splines combine linear and rotational motion, featuring a spline nut and rotary cross roller bearings. They are designed for applications requiring both types of motion, such as in SCARA robots and assembly machines. This type of NB bearing allows for both linear (sliding) and rotational movement. NB's rotary ball spline product line, characterized by its compact size and high rigidity. They utilize a combination of spline nut and rotary cross roller bearings within a structure featuring arch-shaped grooves on both the shaft and the spline nut. This design allows for higher load capacity and longer travel life compared to conventional ball bushings. These splines are suitable for SCARA robots, vertical shafts in assembly machines, loaders, and other applications needing both linear and rotational movement.
