Product Features

  • Single row, deep-groove ball bearing for applications that support high speeds, axial loads in both directions, and radial loads
  • 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
  • CN (normal) radial clearance for applications where thermal expansion is not a factor

Product Description

This Dynaroll R-Series ball bearing is double sealed, has a flanged outer ring, and is made of American Iron and Steel Institute (AISI) 52100 chrome steel. The single-row, deep-groove ball bearing is suitable for applications that support high speeds, axial loads in both directions, and radial loads. It 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 ball bearing is for use in commercial and industrial applications including generators, pumps, original equipment or replacement parts in motors, office automation, farm equipment, and conveyor rollers.

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.

I was shipped 2 of these bearings. The packaging is OEM Dynaroll heat sealed bag. The package states that the product is a flanged bearing. Looking at the bearing through the packaging it is obvious that the bearing has no flanges. I will not buy Dynaroll again.

Although the picture and text describe a "flanged" bearing---IT IS NOT!

The sealed bag, the bearing is in, also states that it is flanged. I should have been more cautious as a previous reviewer had the same problem------thought surely they would have worked it out by now. Beware---Beware
