Key Features

  • Single-row, unground ball bearing for applications supporting moderate loads and low speeds
  • Full ball complement for a higher radial load carrying capacity than a standard caged ball bearing
  • Open configuration for lubrication applied in place
  • Flanged outer ring for easier mounting and positioning than straight bearings
  • Normal radial internal clearance for applications where thermal expansion is not a factor

Product Description

This The General 30000 Unground Flanged series single-row ball bearing is an open bearing, and has a full-ball complement, flange, and normal clearance rating. It is suitable for applications supporting moderate loads and speeds of up to 1,500 revolutions per minute (RPM). The raceways are filled with a full complement of precision steel balls to provide a higher radial load carrying capacity than ball bearings with standard cages. Its open design facilitates lubricating the bearing in place and dissipating heat. An external flange on the outer ring provides easier mounting and axial positioning in the housing than straight bearings. The bearing has a normal radial internal clearance designation, making it suitable for applications where the load and speeds do not result in thermal expansion. This clearance provides latitude for self-realignment and compensates for static and dynamic alignment errors. This unground flanged ball bearing is for use in commercial and industrial applications including appliances, displays, business machine, toys, and conveyor rollers, among others.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.

General Bearing Corporation (GBC) manufactures ball bearings, roller bearings, and other bearing components under the Hyatt and The General brands. The company, founded in 1958, is headquartered in West Nyack, NY, and meets International Organization for Standardization (ISO) standards for quality assurance.
