Rexroth CKK and CKR compact modules series designed for small handling applications to large loads and extended lengths.
Rexroth has introduced size ranges for its CKK and CKR families of compact modules, including size 9-70 and size 25-200. For the size 9-70, designed for smaller positioning tasks, users can choose between ball screw (CKK) and toothed belt (CKR) versions in customer-specified lengths up to 600 millimeters (CKK) and 1,500 millimeters (CKR). Each module consists of a rigid aluminum housing 70 millimeters wide and 32 millimeters high including the carriage plate and features two ball rail systems.
For longer lengths, higher speeds and larger payloads Rexroth CKK and CKR Compact Modules are available in a 200mm wide extrusion utilizing two Size 25 Ball Rail guides. The belt-drive CKR Compact Module uses a low-wear, steel-reinforced polyurethane belt with aluminum pulleys to deliver speeds up to 5 m/s over distances up to 10,000 mm. The ball screw drive version CKK offers a stroke length of 5500 mm. The maximum load capacity for both models is 9100 kg, or 20,000 lbs.
