Product Overview: The IR 20x25x30 Needle Bearing Inner Ring
The IR 20x25x30 is a high-precision inner ring designed specifically for use with Needle Roller Bearings. With a bore diameter of 20mm, an outer diameter of 25mm, and a width of 30mm, this component provides a hardened and precision-ground raceway surface for needle rollers. It is an essential part in applications where the shaft cannot be hardened and ground to the required specifications. By using an inner ring, engineers can use softer, more economical shaft materials without compromising the performance or lifespan of the bearing assembly.
As a key component in many industrial and automotive systems, the IR 20x25x30 ensures smooth, low-friction operation and optimal load distribution. It is typically paired with drawn cup needle roller bearings or needle roller and cage assemblies. Explore our full range of Inner Rings to find the perfect solution for your mechanical application.
