Product Definition

What Is COM SS Stainless Steel Spherical Bearings?

COM SS Stainless Steel Spherical Bearings are spherical plain bearings made from an inner spherical ring and an outer race that permit controlled rotation, oscillation, and angular misalignment. These bearings are commonly installed in rod eyes, cylinder ends, suspension links, lifting equipment, agricultural machinery, and other slow-moving pivot points. Confirm fit, race material, seals, lubrication, load direction, and edge support before installation.

Typical Applications

Applications for COM SS Stainless Steel Spherical Bearings

Hydraulic Cylinders & Lifting Equipment

Hydraulic Cylinders & Lifting Equipment

Spherical plain bearings accommodate angular misalignment and oscillating motion at cylinder eyes, lifting arms, and other pivot connections. Select the race, seals, lubrication, and load direction for the duty cycle.

Construction, Agricultural & Material-Handling Pivots

Construction, Agricultural & Material-Handling Pivots

These bearings are commonly used at heavily loaded pivot points in construction, forestry, agricultural, and material-handling machinery where slow oscillation, shock, contamination, and service access influence the bearing choice.

Automotive Suspension & Structural Linkages

Automotive Suspension & Structural Linkages

The spherical inner and outer surfaces support controlled angular movement in suspension links, axle connections, and fabricated mechanisms. Confirm bore fit, housing support, edge loading, and required misalignment before installation.

Industrial Machinery

Industrial Machinery

Used in industrial mechanisms, fixtures, and fabricated assemblies where compact stainless spherical-bearing geometry and radial support are both required.

Marine & Harsh Environments

Marine & Harsh Environments

Chosen where corrosion resistance, stainless materials, and PTFE-lined articulation help improve service life in marine or washdown conditions.

OEM Mechanical Assemblies

OEM Mechanical Assemblies

Frequently specified for OEM builds that need repeatable stainless spherical-bearing geometry, compact packaging, and low-maintenance lined construction.

Product FAQ

Frequently Asked Questions

What is COM-SS used for?

COM-SS is used in articulated joints and spherical-bearing positions where stainless construction, PTFE-lined movement, and corrosion resistance are preferred.

What makes COM-SS different from standard COM series bearings?

COM-SS uses heat-treated stainless steel components with PTFE-lined construction, making it better suited to corrosive environments and low-maintenance bearing applications.

Does COM-SS use a PTFE liner?

Yes. COM-SS is supplied as a PTFE-lined spherical bearing, combining corrosion-resistant stainless components with low-friction lined articulation.

What materials are used in COM-SS spherical bearings?

COM-SS uses a 440C stainless steel ball, heat treated and precision ground with hard chrome plating, together with a heat-treated stainless steel race and PTFE-lined construction.

Are other stainless race materials available?

Yes. Optional race materials can include 420SS, 304SS, 316SS, and 17-4SS depending on the application requirement.

How do I choose the right COM-SS size?

Start with the required bore, outer diameter, width, ball size, and radial load shown in the size chart, then confirm that stainless PTFE-lined construction fits the environment and duty cycle.
