For engineers, mechanics, or anyone dealing with heavy machinery, this Koyo B-1412 needle roller bearing is a high-performance component. It's a full complement drawn cup bearing, which means it's packed with rollers (no cage) to provide a higher radial load capacity than caged designs. The dimensions are in inches: the inner diameter (ID) is 7/8\, the outer diameter (OD) is 1-1/8\, and the width is 3/4\. It has a smaller cross-section than machined bearings, making it ideal for applications where space is tight. The rollers are made from through-hardened, high-carbon chromium steel with contoured ends to distribute contact stress evenly, ensuring durability and heat tolerance. It can handle a maximum rotational speed of 4800 RPM, a static load capacity of 10,200 lbf, and a dynamic load capacity of 5,370 lbf. This bearing meets the ASTM F2162 standard for quality assurance. It's commonly used in automotive and truck transmissions, agricultural and construction equipment, pumps, compressors, two-cycle engines, and various industrial machinery. Koyo Bearings is a reputable manufacturer headquartered in the USA, meeting ISO quality standards. If you're replacing a worn bearing or need a reliable component for a high-load, high-speed application in a confined space, this Koyo bearing is a top-tier choice. Make sure to check your specifications before ordering to ensure it's the right fit for your project.
