Adjusting preload on Low Profile Redi-Rail Linear Guides

Adjusting preload on Low Profile Redi-Rail Linear Guides

Linear guides of the Low Profile Redi-Rail® product line feature a compact 19 mm profile, enabling seamless integration into tight spaces where other linear guides cannot fit. Constructed with a lightweight aluminum anodized rail and hardened steel races, Low Profile Redi-Rail guides support loads up to 110 lbs, ensuring durability and reliability. They excel in applications like automated beverage kiosks and small-scale cabinetry, providing smooth, low-friction motion for actuator systems requiring confined, precise linear movement.

While carriages come with a factory-set preload, you have the option of adjusting depending on your application needs. This video above demonstrates how to adjust your pre-load into our Low Profile Redi-Rail linear guide carriages in order to provide high performance travel specific to the customer’s application.

In this video, we join one of our knowledgeable product managers as he demonstrates how easy the LPRR carriage can be adjusted using the standard side-adjustable configuration. This video will soon be updated to show the now standard size profile carriage of 19 mm, but is still helpful in showing the process of adjusting pre-load without un-installing the linear guide from the application.
