R165181320 Bosch Rexroth Ball Runner Block
The Bosch Rexroth R165181320 is a high-precision, standard Ball Runner Block (BSHP series) designed for industrial linear motion applications where high rigidity, extreme load capacity, and smooth dynamic movement are critical. Featuring a Flanged configuration in Normal length and Standard height (FNS), this Size 20 runner block is manufactured from premium carbon steel (CS) to ensure maximum mechanical structural integrity.
This model is engineered with a C1 Preload Class (low/moderate preload) and an H Accuracy Class (High), optimizing travel accuracy by up to six times through Rexroth's patented entry zone layout.Built to deliver identical load ratings in all four major directions of force, it permits high torque resistance even when utilizing a single runner block per rail setup.It comes factory pre-lubricated with Dynalub 510 grease and is equipped with a standard comprehensive all-around sealing mechanism to block dirt and contaminants in harsh workshop or CNC routing environments.
