Model RG Linear Drive / Actuator Specifications
Simple design and operation make Uhing RG linear drives less costly to operate and maintain. RG linear drives accuracy is to within ± 0.005".

Two styles of RG linear drives - RG3 and RG4 - offer either three or four rolling rings inside the housing. Adding a fourth ring doubles the axial thrust without going to a larger size drive.

Rate of linear movement

Each size Uhing Model RG linear drive has a different maximum linear pitch – the linear distance the drive travels per one shaft revolution. The higher the motor RPMs, the faster the drive will travel its maximum linear pitch.

The pitch dial on the Model RG drive enables a 10:1 turndown on linear pitch. This is accomplished without changing gears or adjusting motor speed.

For example, the Model RG3-15-2 has a maximum linear pitch of 11.4 mm. With the pitch dial set at number 10, the drive will travel 11.4 mm with each shaft revolution. By turning the pitch dial to number 1, users reduce the travel distance (and therefore linear speed) per shaft revolution to 1.14 mm – regardless of motor speed.

The following chart lists Uhing drives with their respective maximum linear pitch ratings.

NOTE: When using a Model RG rolling ring drive, if the linear speed exceeds .25 M/sec (meters per second), special modifications are needed to the reversal mechanism. Please contact Amacoil for information: 1-800-252-2645.
