Actuators suit high payload and extended length applications.

Press Release Summary:

CKK and CKR Compact Module electromechanical actuators are available in 200 mm wide extrusion utilizing two size 25 Ball Rail® Systems for length, speed, and payload. Belt-drive CKR Module uses low-wear, steel-reinforced polyurethane belt with aluminum pulleys to deliver speeds up to 5 m/s over distances up to 10,000 mm. Ball screw drive version CKK offers stroke length of 5,500 mm. Load capacity for both models is 20,000 lb max.

Original Press Release:

New Size 25-200 CKK and CKR Compact Modules from Rexroth Bring Speed and Precision to Applications with High Payloads and Extended Lengths

Bosch Rexroth Corporation will display its size 25-200 CKK and CKR Compact Modules at the National Design Engineering Show, March 21-23, in Rosemont, IL, Booth # 18001

The proven performance of Rexroth CKK and CKR Compact Modules is now available in a 200mm wide extrusion utilizing two Size 25 Ball Rail Systems for the longest lengths, highest speeds, and highest payloads in the industry. Widely used for multi-axis pick-and-place systems in assembly environments, dispensing operations in the medical industry and material handling in the packaging industry, these electromechanical actuators now bring their trademark speed, precision and heavy payload capability to larger scale applications.

The dual Ball Rail® System linear guides, and in the case of the CKK, the Rexroth Ball Screw, ensure high system rigidity to move heavy payloads or complex end-of-axis tooling with extreme precision. 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-a best-in-class stroke length. Even the ball screw drive version CKK offers a stroke length of 5500 mm-outstanding when ballscrew precision is required. The maximum load capacity for both models is 9100 kg, or 20,000 lbs.

The low-profile, anodized aluminum extrusion fits many applications, and the rigidity designed into the extrusion minimizes deflection. The dual Ball Rail guides inside the modules produce extremely smooth travel along the length of the axis, and convenient clamping fixtures make the Compact Modules easy to mount to virtually any baseplate or surface. The combination of extended length and heavy load capacity makes these new modules ideal for heavy automotive handling applications, transport tasks over long distances, palletizing, box transfer and even pharmaceutical dispensing.
