Timken RCJ1 Flange Unit, 4 Bolt Holes, Industrial-Duty, Relubricatable, Non-Expansion, Cast Iron, Eccentric Locking Collar, Inch, 1" Bore Diameter

This Timken RCJ series cast iron flanged cartridge bearing unit is composed of a cast iron flanged housing equipped with four bolt holes for use in industrial field applications. Within the housing is a double rubber sealed single row ball bearing that has a wide, extended inner ring for increased support to the shaft and can accommodate additional lubrication. The bearing locks to the shaft with an eccentric (asymmetric) self-locking collar that is secured with a setscrew. The housing has a stainless steel grease fitting for lubricating the bearing unit. As a general purpose unit for high contaminant applications, the bearing comes assembled and prelubricated. RCJ series cast iron flanged cartridge bearing units are used in industrial field applications where excessive moisture and contaminants are common, such as agriculture, fisheries, mining, and logging, among many other applications.

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.
