Redi-Rail Linear Guide Rails and Cam Roller Bearing Sliders

Linear guide rails and cam roller bearing sliders of the Redi-Rail line feature innovative carriage sliders that glide along hardened steel gothic arch raceways running continuously along the full length of the linear rail, supporting consistent motion and even load distribution from end to end.

These guides are an excellent alternative to profile rails for applications requiring high speeds, precision, and moderate load capacities. The carriage sliders, equipped with sealed double-row cam roller bearings, travel effectively over debris and particles, helping maintain operation in contaminated environments.

Redi-Rail provides robust strength, straightforward installation, and strong corrosion resistance, making it a dependable linear motion solution for applications such as automation, machine transfer, and material handling.

This is one of several articles that explores the properties and features of Redi-Rail linear guides. In this article we offer a brief overview with focus on our new 4- and 5-wheel carriage options and their implications on cantilevered loads and cost. Redi-Rail linear guides consist of a slider or carriage riding along an extruded aluminum rail. Aluminum rails are integrated with hardened steel races for a strong, yet lightweight design. They are also end joinable for long length applications, ensuring a sturdy design with rigidity and precision. Running parallelism is held to ±.001’’ (.025mm) for the length of the guide rail.

Red-Rail sliders or carriages consist of durable anodized aluminum with three, four, or five gothic arch rollers that are offset and trapped between the round inner races of the linear rail. They are sealed against contamination and engineered with double-row bearing rollers that glide over particulates along the rail. Redi-Rail linear guides are available in commercial-grade inch, or in higher precision metric systems that are equipped with wipers and patented side pre-load adjustment (wipers optional on inch series).

4- and 5-wheel Carriages Benefit Cantilevered Loads and Costs

Previously, a cantilevered load might require a second carriage on the same rail, or even a second rail in parallel with the first to properly address the resulting forces (fig. 2).

These additional components add material cost, as well as increased man-hour costs for assembly and installation time. By substituting a four- or five-roller carriage, designers may now be able to save by implementing a single, longer carriage and shorter rail and still achieve the same result.
