Cast in carbon steel (CS), this long slimline runner block is size 25 and features four rows in an O-arrangement with integrated sealing for reliable operation in dusty or oily environments. Built for high-load linear motion where transverse space is limited, it provides recirculating ball bearing guidance with low-friction travel and precise guidance. The block ships without a ball chain and is part of Rexroth’s B.RUNNER BLOCK family, offering standard accuracy (N) on a compact form factor optimized for tight machine layouts. Typical applications include compact axes in CNC machines, automation equipment, and precision positioning systems where a robust, durable carriage is required on Rexroth rails; the combination of CS material, sealed design, and four-row guidance supports long service life and repeatable positioning in demanding industrial environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Rexroth","offers":[{"title":"New","offer_id":46284723224810,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-023.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/bosch-rexroth-r162321420-ball-runner","provider":"GTG Hardware","version":"1.0","type":"link"}
