Precision steel shafts with shaft support rails Bosch Rexroth

Ball bushing guides Bosch Rexroth

Bosch Rexroth precision steel shafts with shaft support rails are continuously supported shafts for ball bushing guides. The WU series support rail carries the shaft over its full length and absorbs deflection under load. The range covers sizes WU25, WU30 and WU80 in several versions (AF, AF1, AF2, AFH, AS2, SFRA) and lengths (600 and 1800 mm), each assigned by R part number.

📏 Continuous support - the support rail carries the shaft over its full length and limits deflection.
Sizes - WU25, WU30 and WU80 for the respective shaft diameters.
🔩 Versions - variants AF, AF1, AF2, AFH, AS2 and SFRA in the type key for mounting and interface.
🏭 Lengths - defined lengths such as 600 and 1800 mm from stock.

Typical applications: Continuously supported shafts are used for long travel and higher loads where an unsupported shaft would deflect too much, such as gantries, feeders and long handling axes. Selection follows shaft diameter (WU25, WU30, WU80), support version and length (600 or 1800 mm) according to load and travel. The matching ball bushing is found in the related category.
