RHP LRJ2.1/4J single-row cylindrical roller bearing, inch series, made in the United Kingdom. Design Units: Inch. Bore / Shaft Size: 2-1/4 in (57.15 mm). Outside Diameter: 4-1/2 in (114.3 mm). Overall Width: 7/8 in (22.225 mm). Number Of Rows: 1. Rolling Elements: Cylindrical rollers. Bearing Material: Steel. RHP is an NSK brand.
Series: LRJ — the RHP light inch cylindrical roller journal series. Base Number: LRJ2.1/4. The size token 2.1/4 is the bore in inches. Cage Type: Pressed. Cage Material: Steel. Internal Clearance: CN, the normal radial clearance class. The full order code is written LRJ2.1/4JCN and appears on cartons as LRJ-2.1/4-J-CN.
A cylindrical roller carries load on a line contact rather than a point, so radial capacity and rigidity are far higher than a ball bearing of the same envelope. Contact Angle: none — the rollers run parallel to the shaft axis and the bearing is a radial type. CN clearance is the standard fit for a bearing running on an interference-fitted shaft at ordinary temperature. The pressed steel cage keeps rotating mass low.
Bore Type: Straight. The rings are separable: the inner ring and the roller-and-cage assembly mount independently of the outer ring, so each ring can be fitted to its own seat and the two brought together on assembly. That suits an interference fit on both the shaft and the housing at once.
Unit Quantity: 1 Pc. One complete bearing, inner ring, roller and cage assembly and outer ring together.
The designation is also written LRJ2.1/4J, LRJ 2.1/4 J, LRJ2.1/4JCN and LRJ-2.1/4-J-CN. The RHP inch cylindrical range steps by bore: the LRJ2.1/2J on the next size up measures 2-1/2 x 5 x 15/16 in, so it is a related size rather than a substitute. Match the full 2-1/4 x 4-1/2 x 7/8 in envelope before substituting.
