This is a specific industrial bearing – a Koyo drawn cup needle roller bearing, part number JH-1412. If you need this, you probably know what you're looking for. But here are the key specs: The inner diameter (the hole) is 7/8 of an inch. The outer diameter is 1-3/16 inches. The width is 3/4 of an inch. Its maximum rotational speed is 15,000 RPM.
It's called a 'drawn cup' bearing, which means the outer shell is made from thin, stamped steel. This makes the whole bearing have a smaller cross-section, so it's perfect for tight spaces where you can't fit a bigger, bulkier bearing. The steel cage inside keeps the needle rollers evenly spaced, which reduces friction and noise, especially at high speeds. The rollers themselves are tough, hardened steel.
These are commonly used in things like automotive transmissions, power tools, industrial machinery, pumps, and gearboxes – anywhere you have a rotating shaft that needs support with high load capacity in a compact area. It's an open bearing (no seals on the ends), and it meets industry quality standards (ANSI/ABMA). Make sure the dimensions match your old part exactly.
