1 9 Bosch Rexroth Corporation R310A 40 (1.11) MLR Product Description Characteristic features MLR...: with Cam Roller Guide and Toothed Belt Drive for high-speed applications (up to 10 m/s) with Cam Roller Guide to be lubricated with oil only! The MLR... comprise: a compact, anodized aluminum profile frame the integrated Rexroth Cam Roller Guide system with internal cam rollers cam rollers, clearance-free adjusted via eccentric shafts a carriage with one-point oil lubrication for all cam rollers the pre-tensioned toothed belt mountable switches an AC servo motor with control units gear unit a cover provided by the toothed belt For mounting and maintenance, see the relevant Instructions. MLR Linear Module with Cam Roller Guide and Toothed Belt Drive The special design of the integrated zero-clearance Rexroth Cam Roller Guide makes it ideal for very high speeds (up to 10 m/s).

3 94 Bosch Rexroth Corporation R310A 40 (1.11) MLR Technical Data Deflection A particular feature of is that they can be installed as cantilevered axes. Deflection must, however, be taken into consideration, because it limits the possible load. If the maximum permissible deflection is exceeded, additional supports must be provided. f max L/ L F Maximum permissible deflection f max The maximum permissible deflection f max depends on the length L and the load F. f max must not be exceeded! If high system dynamics are required, supports must be provided every 300 to 600 mm. Example Linear Module MLR 10-80: L = 3000 mm F = 500 N From chart 10-80: f = 0.9 mm f max = 3.4 mm The deflection f lies well below the maximum permissible deflection f max, so no additional supports are required.
