Bearings • Spherical Bearings

Spherical bearings are self-aligning bearings designed to manage high radial loads when misalignment, poor lubrication, contamination, extreme speeds or critical application stresses are present. The bearings are able to handle high loads because they utilize two rows of rollers that are thicker in the middle and thinner at the ends. The bearings also have higher friction than a comparable ball bearing, as different parts of the spherical rollers run at different speeds. Spherical roller bearings can feature brass cage or steel cage, and can be window type or finger type. Some can also handle axial loads.

  • Hirschmann Engineering

    Hirschmann is a manufacturer of spherical bearing products, including relubricatable heavy-duty, maintenance free heavy-duty, heavy duty requiring maintenance, and sealed spherical bearings. Relubricatable heavy-duty and maintenance-free heavy-duty spherical bearing types offer friction pairing steel on heavy-duty bronze. Downloadable CAD files are offered. Inch size spherical bearings offer friction pairing steel on PTFE stainless steel supporting  fabric. CAD files are downloadable for these as well. Sealed spherical bearings can be provided with relubricatable and maintenance-free rod ends.

  • Aurora Bearing Co.

    Aurora Bearing Company is a manufacturer of spherical inch and metric bearings and rod ends. All of these bearing types are available in an Aerospace Series and a Mil Spec Series, as well as for the commercial and industrial markets. Aurora's spherical inch bearings provide ball-to-race conformity and race materials are low carbon, heat treated alloy, or stainless steel. A self lubricating PTFE to metal interface may be optionally specified. Aurora Bearing also produces three lines of metric spherical bearings. All feature one-piece steel raceways. Their rod ends come in inch or metric sizes as well, and feature steel raceway construction and a low friction, high wear resistance molded liner.

  • WD Bearing

    WD Ball & Roller Bearings is a manufacturer of spherical plain bearings, rod ends, and spherical roller  bearings with symmetrical double row spherical rollers self aligning in the groove of the outer ring. They also offer thrust spherical roller bearing products. Spherical plain bearings and rod ends come in radial, angular contact, thrust, rod end, and ball joint types. Also offered are spherical plain radial bearings with a fitting crack, maintenance-free spherical plain radial bearings, spherical plain radial bearings with a fitting crack and wide inner ring, and maintenance-free rod ends with a female thread.

  • Taylor Hobson Limited

    Taylor Hobson is a manufacturer of spherical roller bearings. Most have an outer raceway that is a portion of a sphere for self aligning qualities. Each roller  has a curved form at right angles to the direction of rotation. This provides a high radial load carrying capacity. Other bearing products offered by Taylor Hobson include cylindrical and tapered roller bearings, and angular contact ball bearings.

  • NTN Bearing Corp. of America

    NTN is a manufacturer of self aligning spherical roller bearings designed for heavy radial loads, automatically compensating for large angular errors. Standard Type B spherical roller bearings perform well under high speeds. Their EA Series works well at high temperatures. The EM Series features a solid copper alloy cage for high impact and high speed applications. Other bearing products include radial, miniature and angular contact ball bearings, cylindrical, tapered and needle roller bearings, and ball and roller bearing mounted units.

  • Aetna Screw Products Co.

    Aetna Screw Products is a manufacturer of spherical ball bearings. The COM and COM-T Series spherical ball is made of 52100 steel, while the bearing body is made of low carbon steel. These spherical ball bearings incorporate a permanently bonded Teflon liner to the inner diameter of the race. Other products available include spherical rod ends, metric rod ends, ball joints, and threaded ball studs.
