With a bore size of 2.25 inches and an outer diameter of 3.563 inches, this bearing is engineered from heat-treated 52100 steel, ensuring exceptional durability and resistance to deformation. Its innovative lubrication system features grooves and holes that direct grease efficiently, making maintenance straightforward and effective. ## Description This RBC single-acting spherical plain bearing inner ring is unsealed and is suitable for use as a replacement ring for use with a corresponding RBC single-acting-style outer ring. This spherical plain bearing ring supports heavy radial and single-direction thrust loads for applications that provide high misalignment adjustment. The race is made of 52100 steel for durability and resistance to deformity under heavy loads and is heat-treated to Rockwell C-scale 57 hardness. Lubrication grooves and holes in the race direct grease into the bearing. This spherical plain bearing ring has an open configuration for lubrication in place and is intended for use in pivoting, high load bearing applications such as kingpin applications in farm machinery.Plain bearings provide low-friction sliding contact for relative motion between parts of a machine. They are the simplest type of bearing, with no rolling elements, and there are three basic types of plain bearings: radial plain bearings (also called sleeve bearings or bushings) to support rotating or reciprocating shafts, thrust bearings (also called washers) to support axial loads on shafts, and linear bearings to support and guide the motion of parts in a straight line. Flanged sleeve bearings have a flange on one end to support axial loads. Spherical plain bearings are radial bearings that allow for angular misalignment of the shaft. Plain bearings are made from durable, low-friction materials such as sintered or cast bronze alloys, plastic, or a combination of a metal shell and a plastic bearing surface. They can be lubricated externally or by a lubricant embedded in the bearing material. Plain bearings are used in automobiles, construction and mining equipment, textile manufacturing equipment, and robotics, among others.RBC Bearings manufactures bearings, pins, rollers, and shafts, and other products for industrial and aerospace applications under the RBC, Nice, Heim, Unibal, and Spherco brands. The company, founded in 1919 and headquartered in Oxford, CT, meets International Organization for Standardization (ISO) standards 9001:2008 and ISO/TS 16949:2009. ## Features - Replacement inner ring for use with RBC single-acting type outer bearing ring - Supports heavy radial and single-direction thrust loads - Heat-treated 52100 steel ring for durability and resistance to deformity under heavy loads - Lubrication grooves and holes in ring direct grease into bearing - Open bearing for lubrication in place ## Images ![RBC Bearings IRB36SA 2.25 " Bore x 3.563 " OD x 1.39 " Width Unsealed Spherical Plain Bearing - Image 1](https://m.media-amazon.com/images/I/818SNhk0RXL.jpg) ## Available Options This product comes in different **Bore Diameter String, Item Diameter String, Item Width String** options. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/6692698-rbc-bearings-irb36sa-2-25-bore-x-3-563-od](https://www.desertcart.com.cy/products/6692698-rbc-bearings-irb36sa-2-25-bore-x-3-563-od) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-23*
