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.
Selecting the correct product from our website is a simple process, just pick the dimensions you want from the drop-down menus shown at the top of the product category page. If you need more detail on a specific product you can click on the Technical tab from its page to see a full list of dimensions along with a sectioned drawing which should give you all the information you need to make sure you're getting the right item. If there are any questions that the website doesn't answer, you can always give our customer services team a call, or drop them an email and they'll be happy to help with your query.
When you're ready to buy, ordering from our website is fast and secure, or you can give us a call and buy over the phone if you prefer.
