Needle Roller Inner Rings
Used in situations where a larger width is needed but run out tolerances are less important, needle roller inner rings are an economical answer that can be used in conjunction with a range of cage type and needle roller bearings.
Here at Simply Bearings, we supply needle roller inner rings made from hardened carbon chromium steel. They have a ground bore and outer diameter with sides and edges that are only smoothed. We stock needle roller inner rings with inside diameters from 5mm up to 440mm and outside diameters from 7mm to 490mm, plus widths from 9.75mm up to 160mm. The rings are produced by major brands including IKO and economy versions are available too, for those on a tight budget.
