Product Name Notes
Angular contact bearings (as shown in Figure 7) are best suited for applications with single direction, thrust load. When thrust load reverses, angular contact bearing will separate. Therefore, for applications...
For application requiring extra load carrying capacity, NPB offers heavy duty spherical plain bearings. With the same bore diameter options as our standard series, the heavy duty series has larger...
For applications requiring additional axial space, NPB offers extended inner ring spherical plain bearings (as shown in Figure 5). This type of bearing eliminates the need for an extra spacer...
National Precision Bearing offers sealed spherical plain bearings to minimize the ingress of contaminants on to the bearing rotating surface and to help keep lubricant within the bearing (as shown...
Rod End Bearings offered as self-lubricating with TFE liners for reduced friction. Also can be supplied as metal to metal types. They are recommended for applications requiring considerable oscillation and...
Self-Lubricating bearings (as shown in Figure 6) do not require grease or oil for lubrication. Instead, they utilize a liner system bonded to the inside diameter of the outer ring.
Spherical plain bearings are designed to provide rotational motion in omni-direction. There are primarily two types of spherical plain bearings, radial and angular contact. Spherical plain radial bearings offer high...
The unique two piece design of the slotted-entry bearing features a ball (inner ring) which has a spherical race to accommodate misalignment. The outer ring/rod end has an entry window...
