Key Features

  • Single row, deep-groove clamp-type collar bearing supports both axial and radial loads
  • Two-piece collar allows for easier installation and disassembly than standard bearings
  • Buna-n rubber seal on both sides of the bearing keeps lubricant in and contaminants out
  • AISI 52100 chrome steel for durability and resistance to deformity under heavy loads
  • Stainless steel cage evenly spaces balls for reduced friction, vibration, and noise

Product Description

This Dynaroll clamp-type collar bearing is double shielded, has a flanged outer ring, and is made of American Iron and Steel Institute (AISI) 52100 chrome steel. This single-row, deep-groove clamp-type collar bearing supports both axial and radial loads. The clamp collar allows for easier installation and disassembly than standard bearings. The two-piece collar bearing has a split inner ring with a mounting collar that is secured to a shaft using a hex-type set screw, improving shaft support and simplifying installation by eliminating the need to press-fit the bearing onto the shaft. The ball bearing has deep inner and outer races that conform to the balls that run in them, allowing higher speeds and creating lower friction than bearings with comparable-sized roller bearings. The Buna-nitrile (Buna-n) seal on either side of the bearing fastens to the outside ring, extends over the rolling elements, and makes contact with the inside ring to keep out contaminants such as dirt and grime. The seals also hold in a lubricant applied during manufacturing that lasts the lifetime of the bearing. The inner and outer rings and balls are made of low-alloy, through-hardened AISI 52100 chrome steel for durability and resistance to deformity under heavy loads. This bearing has a stainless-steel cage to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise, and an external flange on the outer ring for easier mounting and axial positioning in the housing than straight bearings. It can be used to a maximum operating temperature of 121 degrees C/250 degrees F. The bearing has a CN (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 clamp-type collar bearing is for use in commercial and industrial applications including packaging machinery, food and beverage processing, conveyor equipment, paper and printing machinery, and pumps.

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.

Dynaroll Corporation manufactures miniature bearings and ball bearings that meet International Organization for Standardization (ISO), Occupational Health and Safety Assessment Series (OHSAS), Production Part Approval Process (PPAP), and U.S. Food and Drug Administration (FDA) Critical standards for quality assurance. Founded in 1988, Dynaroll is based in Sylmar, California.
