The INA cylindrical roller thrust bearing, series K81136-M, is built to handle high axial loads in a single direction. With cylindrical rollers and a brass cage, it delivers precise operation where axial rigidity and load capacity are critical. Typical uses include industrial machinery, transmission equipment, and assemblies with dominant axial thrust.

The part number follows a simple pattern: the K prefix, a numeric size code, and the -M suffix for the brass cage. For instance, K81136-M identifies a bearing with a specific bore diameter. The same logic applies to K81138-M, K81140-M, K81144-M, K81148-M, K81152-M, K81156-M, and K81160-M. Each number marks a distinct size, not a generic series.

These bearings suit applications where axial forces dominate and high load capacity is needed. You will find them in presses, extruders, cranes, lifting equipment, and machine tools. They also appear in gearboxes and transmission systems that endure significant axial thrust. Industries such as metallurgy, cement, mining, and heavy machinery manufacturing rely on them.

Selecting the right bearing requires knowing the axial load, rotational speed, and environmental conditions. Because these bearings are not self-aligning, check the alignment of the support surfaces. Proper lubrication and sealing against contaminants help extend service life. Use suitable tools during mounting to avoid damaging the rollers and raceways.

For equivalents, INA cylindrical roller thrust bearings can be interchanged with other brands that follow the same standardized dimensions. Always verify tolerances and load capacity before replacing a component. Interchangeability depends on matching dimensions and cage design. Our team can help validate compatibility.
