An Overview of Cam Roller Technology

In this video, we offer a brief synopsis of the Cam Roller Technology (CRT) family of bearing systems, as well as their specific linear motion solutions within industry applications. The CRT family has products based on ball and roller bearings that ride within a linear guide rail. The mix of products covers applications from commercial precision, low load and duty cycles to systems with adjustability, high precision high load capacity, and long-life performance. Below is an outline of the five product families that make up the PBC Linear CRT line.

Hardened Crown Rollers

One size fits many needs! These pre-assembled rollers are easy to install and offer low cost, no-nonsense, point-to-point linear motion where low precision is appropriate.

• Pre-assembled rolling element bearing with polymide 6/6 seals
• Angle brackets and end-stops
• Cooper B-Line series rail
• 9/16˝ Hex head

Commercial Rail

Start your search here for sturdy, low-cost linear motion solutions where corrosion-resistance and medium to high load capacities are requested. 

• 3 sizes (45 mm, 30 mm, 20 mm)
• Machined and anodized aluminum alloy slider body for corrosion resistance
• Sealed chrome steel or 440C stainless steel rollers for corrosion resistance
• Zinc-plated or stainless rails for corrosion resistance
• Adjustable center roller to remove play from the system

V-Guide Wheels and Rails

Get the low-cost, high-load advantage! These cam roller components offer customers with a low-cost alternative to profile rail, where lower precision travel is recommended.

• 4 sizes (20 mm, 30 mm, 45 mm, 60 mm)
• Interchangeable with industry-standard sizes.
• Dual row angular contact V-Wheels provide low friction guidance, high speed operation, and high load capacities along all planes of operation.
• Bearings permanently sealed and lubricated for minimal maintenance and long life.
• V-Guide Rail shoulder offers simple mounting and alignment for quick and easy installation.
• Available in either steel or 400 series stainless steel.
• Fixed and eccentric bushings to mount the wheels available in both inch and metric.

Redi-Rail^® 

This combination of precision rails and hardened gothic arch rollers provide the practical precision required in many profile rail applications, but with the added benefits of fewer componenets, easy installation, and a much higher performance within harsh conditions.

• Metric Redi-Rail is available in 3-, 4-, and 5-wheel carriages (inch version is 3 wheels only).
• Low profile version with low height of 19 mm.
• Patented side adjustment feature for preloaded condition.
• Hardened steel raceways embedded in a qualified aluminum rail ensure precision (+/- 0.002˝ per foot straightness).
• Sealed double row ball bearings provide high load capacity and reliable operation within contaminated environments.
• Spring loaded oil filled polymer wipers apply optimal lubrication to the rail to ensure reliable low maintenance operation.
• Speeds up to 10 m/sec (32.8 ft/sec).

Hevi-Rail^® combined bearings and U-channel profiles

Utilize the linear might in motion of Hevi-Rail for a cost effective, high-load capacity linear bearing system. This product is ideal for industrial strength handling applications requiring low to medium precision.

• High radial and axial load capacity systematically handles loads up to 60 tons.
• Combined axial/radial bearing design allows bearings to float within the rail, eliminating the need for precise alignment, reducing installation time.
• Fixed or adjustable eccentric bearings can be adjusted to easily eliminate side-to-side play in a system.
• Case-hardened steel design with internal roller bearings handles heavy loads in dirty environments.
• Bearing pre-welded flange plate offers easy mounting and installation.
