Fairlane Products, Inc. (Fraser, MI) offers a complete line of Covered Bearing rollers and Bearing Cover rollers. Although sounding similar, the primary difference between the two is that Covered Bearings have a smooth-only surface that is cast directly to a precision-sealed ball bearing, while the Bearing Covers have a bearing that is held in place by a snap ring.
CB-series Covered Bearing rollers (also commonly referred to as molded bearings) that have a smooth urethane or Neoprene surface that is cast directly to a precision sealed ball bearing. The main advantage with this covered bearing line is that users have a wider range of durometers to choose from, soft to hard, including 35 to 95 in Urethane and 60 or 80 in black Neoprene. Also, users have the option for a double bearing style which features a wider width roller.
CB-series Covered Bearings are available in a full range of sizes from 3/4" to 3" and 20 to 70 mm diameters with 3/4" to 1-1/8" and 5 to 12 mm widths in single or double bearing options. They are also available with or without mounting hardware. The stud mount style comes complete with a button head cap screw, lock nut and spacer.
Utilizing a different design than the CB Covered Bearing rollers, Bearing Cover rollers are not cast directly to a sealed bearing, but instead the bearings are held in place against the cover wheel by a snap ring. These Bearing Wheel Covers are available in a wider range of materials including nylon which provides thermal and chemical resistant, polyacetal for general use, UHMW and urethane for abrasion resistance, PEEK for high temperatures, steel for general use, and stainless steel for corrosion resistance.
The bearing wheel covers are offered in flat, crowned or radial styles to meet the specific application needs and are available with or without a threaded stud. For stud mount, the rollers come assembled with a low-profile stud permanently swaged into the bearing which replaces the need for a nut, bolt and spacer. They are available in sizes of 3/8" to 1/ 1/2" diameter and 3/4" to 1-1/2" widths.
Both types of rollers provide smooth, quiet and non-marring operation. They are designed to protect the delicate, the fragile, and the unusual. They are often used in material handling applications to guide, stop and support parts that are moved and transferred. They are an easy and economical solution to eliminate the need for custom engineered parts.
