Heavy Duty Sealed & Unsealed Spherical Plain Metric Bearing
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...
Standard Duty Extended Inner Race Sealed & Unsealed Spherical Plain Inch Bearing
Standard Duty Extended Inner Race Sealed Spherical Plain Metric Bearing
Standard Duty Extended Inner Race Unsealed Spherical Plain Metric Bearing
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...
Self Lubricating Sealed Spherical Plain Metric Bearing 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 & Spherical Bearing 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 Sealed Spherical Plain Inch Bearing 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.
Angular Contact (Thrust Type) Spherical Plain Inch Bearing
Standard Duty Sealed & Unsealed Spherical Plain Inch Bearing
Standard Duty Sealed & Unsealed Spherical Plain Metric Bearing
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...
Loader Slots Bearing 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...
