With an outer roller that runs directly on a flat surface, these covers can be used as track wheels and guide rollers and more. Bearing covers are designed to allow the inner diameter of the bearing to spin separately from the outer cover, reducing vibration, friction, noise, and wear of bearings.
Bearing wheel covers are offered in flat, crown, and radial cover types in a wide range of materials to fit your performance needs. Polymer materials include thermal/chemical resistant nylon, high strength PEEK, abrasion resistant 70D urethane and black polyacetal for general use. Wheel covers are also available in corrosion resistant 303 stainless and electroless plated 1045 steel.
PACK EXPO Las Vegas and Healthcare Packaging EXPO (Sept. 27-29, Las Vegas Convention Center) will reunite the packaging and processing community. With over 1400 exhibitors, no other event in 2021 will bring together a more comprehensive gathering of suppliers offering new products, technologies and solutions. Attendee registration is now open.
The versatile bearing wheel covers are offered in a straight bore or threaded stud version. The low-profile mounting stud is permanently swaged into the bearing, replacing the need for a nut, bolt and spacer. The bearing is retained by a snap ring.
Bearing wheel covers for radial ball bearings are available with a rubber sealed bearing or a shielded bearing made from steel or stainless and are offered in a wide range of sizes with outer (OD) wheel diameters ranging from ¾ in. to 1-1/2 in., bore diameters from 3/16 in. to ½ in., and wheel widths from 3/8 in. to 9/16 in.
