R165111320 Bosch Rexroth Ball Runner Block
The Bosch Rexroth R165111320 is a premium Size 15 Ball Runner Block designed for ultra-smooth linear motion and high structural precision in automation and machining systems. Featuring a Flanged design in Normal length and Standard height (FNS), this block is crafted from high-strength carbon steel. Rexroth's global manufacturing footprint ensures that pieces marked or made in facilities like China maintain identical strict tolerances, quality control standards, and geometric cross-compatibility as European productions.
Part of the high-performance BSHP series, it is configured with a C1 Preload Class (low/moderate preload) and an H Accuracy Class (High). This provides excellent rigidity and load-bearing properties across all four main directions of force, allowing the use of individual blocks on single-rail structures without losing dynamic alignment. Outfitted with comprehensive standard end-seals, it is factory pre-lubricated with Dynalub 510 grease to reduce initial installation friction and provide instant resistance to factory dust, metal chips, and particulate debris.
