Needle Roller Bearings with machined rings made of carbon chromium bearing steel have a low sectional height and a very high load carrying capacity for their size. They may be used with or without an inner ring, depending on the demands of the application.

Needle roller bearings without an inner ring are ideal for compact bearing arrangements if the shaft can be hardened and ground. Eliminating the need for a separate inner ring enables a larger shaft diameter and a stiffer arrangement.

Alternatively needle roller bearings with an inner ring are an excellent choice for arrangements where it is not possible or uneconomical to harden and grind the shaft. We can provide needle roller bearings with machined rings in many designs and sizes to suit. If the permissible axial displacement provided by a standard inner ring is insufficient, it is possible to use an extended inner ring. Extended inner rings can also provide an excellent counterface for the lips of external G or SD seals.
