This aluminum runner block houses recirculating ball bearings in a precision housing and is designed to ride along a compatible Rexroth ball rail, forming a linear guidance unit. The part is intended for use in industrial robots and general machine construction where a compact, ball-bearing-mounted longitudinal guide is required. As a standard Rexroth component, it integrates with Rexroth ball rails to deliver controlled linear motion across the length of the installation, enabling accurate positioning of attached tooling or mechanisms in compact footprints.\u003c\/p\u003e\u003c\/div\u003e","brand":"Rexroth","offers":[{"title":"New","offer_id":46284703826154,"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-r163211420-runner-block-ball-rail","provider":"GTG Hardware","version":"1.0","type":"link"}
