NIPPON BEARINGS - SPR 25A

Details

Nippon Bearing (NB) Rotary Ball Spline series, the SPR type. These rotary ball splines are designed to handle both linear and rotational motion, making them suitable for applications like SCARA robots, vertical shafts in assembly equipment, and loaders. The SPR type uses balls and cross rollers within its structure to achieve accurate positioning in both linear and rotational directions. The SPR-A, like other SPR type rotary ball splines, is designed to transfer torque and enable precise positioning in both linear and rotational movements. It consists of a spline nut and a rotating portion, which utilizes either balls (for SPB type) or cross rollers (for SPR type). Nippon Bearing's product documentation notes that the SPR type offers high accuracy in both linear and rotational movements.
