Timken ER Industrial Series Wide Inner Ring Ball Bearing, With Snap Ring, Double Sealed

This Timken ER Industrial Series double sealed wide inner ring ball bearing with a snap ring is for applications that require starting and running at low torque. It has an extended inner ring equipped with setscrews for securing the bearing to the shaft. The bearing is coated with black oxide to make it resistant to corrosion, and the balls are evenly spaced on the raceways with a nylon retainer for reduced friction, vibration, and noise. It has a snap ring on one side for holding the bearing in place, such as to a bearing housing, and has rubber seals on either side that keep out contaminants such as dirt and grime and hold in a high quality lubricant applied at manufacture. ER Industrial Series double sealed wide inner ring ball bearings are designed for use in low torque applications such as heavy industrial machinery.

Specifications

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.

The Timken Company manufactures a variety of bearings, alloy steels, and related components and assemblies that meet International Organization for Standardization (ISO) standards for quality assurance. Founded in 1899, the Timken Company is based in Canton, Ohio.
