Linear Motion Module uses toothed belt drive.

Press Release Summary:




With lengths up to 5500 mm, CKR module achieves speeds up to 5 m/s with smooth running characteristics. External dimensions, accessories, and attachments are identical to company's CKK modules. Available motor mounting positions include front-mounted gear reducers and side drives with timing belt. Both options include various reduction ratios for adaptation of external mass to inertia of motor. Side drive with timing belt also acts as motor support.

CKR Compact Modules with toothed belt drive add speed, versatility



A New Compact Module, CKR, from the Linear Motion and Assembly Technologies division of Bosch Rexroth Corporation uses a toothed belt drive system to achieve high speeds and smooth performance

Rexroth has added a new model to its range of STAR Compact Modules. The new linear system is ideal for high travel speeds over long distances.

Ready-to-mount CKK versions of these new linear systems have long been available with internal Ball Rail® Systems and a Ball Screw drive (CKK). The new version, designated CKR, uses a highly dynamic toothed belt drive system to achieve speeds up to 5 m/s with smooth running characteristics. These modules will be available January 2003, in lengths up to 5500 mm.

In their external dimensions, accessories and attachments the CKR Modules are identical to their CKK counterparts. Two motor mounting positions are available: front-mounted gear reducers or side drives with timing belt - in both cases with various reduction ratios for optimal adaptation of the external mass to the inertia of the motor. The side drive with timing belt also acts as motor support. The motor can be mounted in three different directions on each drive side.

Bosch Rexroth Corporation is a wholly owned subsidiary of Robert Bosch GmbH. In the year 2001 the company had total revenues of approximately $3.42 billion (3.86 billion Euros) and a worldwide total of around 26,000 employees. Divisions include Industrial Hydraulics, Electric Drives and Controls, Linear Motion and Assembly Technologies, Pneumatics, Service Automation and Mobile Hydraulics. Bosch Rexroth - The Drive & Control Company - offers comprehensive solutions for drives and motion control in 80 countries around the world.
