What are the main advantages of using thin wall bearings in industrial applications?

Thin wall bearings offer a space-saving design, excellent load capacity, and low friction. Their single-piece construction and Babbitt lining make them ideal for environments where reliability and smooth operation are essential.

How do thin wall bearings differ from traditional rolling element bearings?

Unlike rolling element bearings, thin wall bearings (or plain bearings) provide a full-contact surface for better shock absorption and smoother operation, especially in high-load, low-speed, or oscillating applications.

Can Quad Industries produce custom sizes and materials for sleeve bearings?

Absolutely. As a specialized plain bearings manufacturer, we can custom-produce thin wall sleeve bearings in a wide range of diameters, thicknesses, and materials to meet your project’s unique requirements.

Small Engine Bearings

Built to Your Print

Quad Industries manufactures small engine bearings for compact engines where the part is small but the tolerances are not. We build them in Babbitt, aluminum, bronze, and tri-metal constructions, as straight or flanged half shells, plain or electroplated, in diameters from 0.750″ to 1.250″.

Materials, Finishes and Size Range

Small engine bearings need a good running surface in a small package. We offer backed Babbitt constructions for a conformable surface, solid bronze or aluminum when a single material does the job, and tri-metal when the load calls for it. A tin flash is available on several options.Available in:

Plain (non-plated)
Electroplated
Straight and flanged half shells

Materials:

Steel-backed Babbitt (tin flash available)
Steel-backed Aluminum (tin flash available)
Bronze-backed Babbitt

Solid Aluminum (tin flash available)
Legacy Tri-Metal (Steel / Bronze / Babbitt)
New Style Tri-Metal (Steel / Bronze / Electroplate)

Size range:

Wall thickness: 0.040″ and up
Diameter: 0.750″ up to 1.250″
