RM-8 Extended Temperature Range Rotary Stage

This version of the RM-8 is designed to operate from -50°C to 80°C. To achieve this low temperature range, we use a specially designed stepper motor, Molykote 33 grease on all bearings and worm gear, and the housing is also modified to allow proper bearing fit at -50°C. The RM-8 design takes advantage of a single preloaded crossed roller bearing for the table movement. This design approach eliminates the use of a dual bearing configuration thus improving on axial runout and wobble. This rotary table utilizes a worm gear drive with a gear ratio of 80:1. The RM-8 is available with an optional home switch and 4000 CPR rotary encoder mounted to the rear of the motor.

An Envirotronics thermal chamber is used to verify operation of each stage at the temperature extremes.[/vc_column_text][vc_column_text][/vc_column_text][/vc_column][/vc_row][vc_row row_type=”2″ blox_padding_top=”45″ blox_padding_bottom=”45″ blox_bgcolor=”#ffffff”][vc_column][vc_column_text]
