SKF Roller Bearing 81111 TN, Cylindrical Thrust, 55mm Bore, 78mm OD, 16mm Width, 1 Row

The SKF 81111 TN is a high-performance cylindrical roller thrust bearing engineered for reliable operation in industrial environments where high axial loads and impact loads are present. With a 55mm inner diameter and 78mm outer diameter, this single-row bearing offers an efficient design that provides outstanding stiffness while occupying minimal axial space in machinery.

Unlike conventional bearings, the 81111 TN is specifically designed to handle axial loads exclusively and must not be subjected to radial forces. Its separable design lets the shaft washer, housing washer, cylindrical roller, and cage thrust assembly be installed independently, simplifying maintenance, handling, and installation. This modularity is particularly beneficial in applications where regular servicing or component replacement is necessary.

The bearing benefits from an optimized cage design and slightly relieved roller ends, a feature that prevents stress peaks by modifying the line contact between the rollers and raceways. This construction enhances overall bearing life and ensures reliable long-term performance even under high load conditions.

With a parallel bore and closed end structure, the SKF 81111 TN delivers secure mounting and reduces risk of misalignment. Its dynamic load rating reaches 69.5 kN and static load rating is 285 kN, underlining its suitability for demanding use in heavy-duty machinery and equipment such as presses, industrial gearboxes, and drive units.

In operation, this bearing can reach a limiting speed of up to 3800 rpm, making it a strong choice for high-speed axial applications. The singular row configuration not only aids in achieving higher load ratings but also contributes to the robust and compact setup of the assembly.

Industries benefiting from such thrust bearings include manufacturing, mechanical engineering, automation, power generation, and renewable energy. The SKF 81111 TN is especially relevant where axial force transmission is critical, such as in screw shafts, vertical shafts, and press arrangements within production lines.
