Module 3 Helical Rack Linear Guide Rack

Rack and pinion is the logical choice when your machine’s precision motion drive exceeds what can quickly and economically be achieved via ball screws. Our products are precision ground and meet AGMA 9 specs. Best of all, our gear rack comes with indexing holes and mounting holes pre-bored. That saves you lots of time, hassle, and expense. Just bolt it to your frame.

Helical Rack and Pinion Vs Ball Screw

Ball screws can swing and vibrate over longer lengths as they hang between the ends. The spiral rack is mounted directly on the precision-machined steel frame/resting on the machined ledges and therefore does not vibrate. Helical rack and pinion drives offer our customers the best of both worlds – high precision, minimal wear for long-term reliability, no vibration, high speed and easy maintenance.

Ball screws can become a place of maintenance issues – as the ball nut rotates and moves along the ball screw, any dirt, dust and debris on the screw can collect inside the ball nut and affect the circulating ball bearing (see example picture for correct). If not cleaned regularly and correctly, ball bearings will begin to wear and stick, leading to problems in the operation of the machine.

We recommend helical rack and pinion drives for better long-term performance and easier maintenance. If the pinion wears out, it is easier and cheaper to replace than expensive ball nuts.
