Needle roller bearings feature small, cylindrical rollers with a "spindle" shape. They are especially useful for applications with limited radial space, due to their low cross-section and high load-bearing capabilities.
The ends of needle rollers are slightly relieved to manage line contact between raceways and the rollers. This prolongs the useful life of needle bearings because it prevents stress peaking at the roller ends.
Needle roller bearings may be classified as either "radial" or "thrust". This naming convention depends on the direction of the supported load. They carry higher loads than other bearings, but cannot handle high speeds. This speed limitation is due to high-speed roller skewing.
Needle roller bearings feature a smaller cross-section than other bearings. Their greater rigidity and smaller size helps to cut down on the weight and size of your overall equipment and systems. Needle bearings also have lower inertia forces, handle oscillation better, are interchangeable with sliding bearings, and can perform under severe conditions.
You can order needle roller bearings in single or double row styles. Their cage assemblies may be solid or split. You can choose needle bearings in metric and inch sizes. They are also available with or without connecting rod bearings, ribs, and inner rings. If necessary, you can order needle bearings in yoke and stud types, as well.
If you require cam followers or rotor followers, let your Hoffmeyer representative help you find the solution you need. You may also need drawn-cup or solid radial bearings, as well as the appropriate adapters, couplings, and attachments. Let us help you every step of the way!
Hoffmeyer's thrust and radial needle bearings work well in a wide variety of applications. Our bearings are held in place by a cage (or full complement case) and display excellent load-bearing characteristics.
With over 90 years experience, our skilled and trusted Hoffmeyer staff can help you choose the right needle roller bearings for your application.
