Needle roller bearings provide an antifriction solution when supporting rotating shafts with radial loads, and ProSource is happy to help you with acquiring them! Needle roller bearings, manufactured from bearing quality steel, use crowned or end-relieved rollers to help reduce end stresses and allow for greater misalignment. The rollers are separated by a steel retainer (cage) to also help reach higher speeds and provide a lubricant reservoir.
ProSource is Chattanooga's Needle Roller Bearings Distributor
Needle roller bearings are available in a variety of designs and a wide range of sizes, leading them to be suitable for an array of applications and operating environments. These are the needle roller bearings we offer here at ProSource:
Radial Needle Roller and Cage Assemblies– These types feature a steel cage that provides inward and outward retention for the needle rollers, providing maximum cage strength consistent with the high load ratings of needle roller bearings.
Drawn Cup Bearings– With drawn cup bearings, the outer ring is in the form of a cup and accurately drawn. They are available in open-ended as well as single closed-end designs.
Machined Needle Roller Bearings– Available in a range of both inch and metric sizes, these bearings come with various features such as integral seals, side flanges, inner rings, oil holes, and single or double-caged sets of rollers.
Track Rollers– Track rollers are designed with outer rings of large radial cross-section designed to withstand heavy rolling and shock loads on track-type and cam-controlled equipment. Some have profiled outer diameters and others have cylindrical.
Thrust Bearings– Thrust needle roller bearings and cage assemblies also come in a variety of sizes, both inches and metric. All types feature very small cross-sections and are available with either needle rollers, or with heavier cylindrical rollers intended for higher carrying loads.
Combined Bearings– Combined radial and thrust bearings consist of a radial bearing, or needle roller bearing, and a thrust bearing, or a ball/roller bearing.

In comparison to other roller bearing types, needle roller bearings have a greater surface area in contact with the races, meaning they are able to support greater carrying loads. They’re also thinner by design and require less clearance between the axle and surrounding components. Other needle roller bearings features include:
- The Machined Outer Race
- The Steel Cage
- The Needle Rollers with End Relief
- The Annular Lubrication Groove
