Product Overview: The HK 4012 Drawn Cup Needle Roller Bearing
The HK 4012 is a high-performance drawn cup needle roller bearing featuring a 40mm bore diameter, 47mm outer diameter, and 12mm width. This bearing is a key component in our Needle Roller Bearings range, specifically designed for applications requiring high radial load capacity within a compact, space-saving footprint. Its unique construction includes a thin-walled, drawn outer cup that acts as a raceway for the needle rollers, which are securely held by a cage. This design is ideal for arrangements where the housing bore cannot be used as a raceway but a very compact and economical bearing solution is needed.
As a leading supplier of industrial components, we ensure our HK 4012 bearings meet stringent quality standards for reliable and efficient operation. This bearing is typically press-fitted into the housing, making installation straightforward. It is an excellent choice for a wide array of industrial and automotive applications where performance and minimal cross-section are critical.
