SKF Thrust Ball Bearing 1 Row , 40 mm ID 90 mm OD Sheet Metal Cage Steel Balls Open End Parallel Bore CN Clearance 53408

The SKF 53408 Thrust Ball Bearing is a precision single-row bearing designed to handle axial loads efficiently in rotating assemblies, particularly for applications where high performance and reliability are required. It features a 40 mm internal diameter and 90 mm external diameter, making it suitable for medium-duty industrial installations. The open end construction facilitates inspection and maintenance, while the sheet metal cage ensures even distribution of the steel balls to reduce wear and extend operational lifespan.

This bearing is engineered for dynamic loads up to 95.6 kN and static loads up to 183 kN, making it ideal for demanding environments such as power transmission systems, rotary actuators, and various mechanical engineering applications. The 38.2 mm race width provides additional stability and precise shaft alignment. The bore is parallel for secure installation, minimizing the risk of vibration and misalignment.

SKF employs bearing-grade steel for the balls, guaranteeing consistent performance and durability. The internal clearance type CN ensures optimal running conditions in typical industrial setups, reducing the risk of excessive friction or thermal expansion issues. With a limiting speed of 3200 rpm, the 53408 is suitable for a range of moderate to high-speed applications wherever robust axial load capacity is needed.

Application fields include industrial machinery, manufacturing equipment, fluid power systems, and rotary actuators in automotive and general engineering. As a thrust ball bearing, it is not intended for radial loads but excels at managing axial forces in a single direction.

The bearing is manufactured in Germany and meets stringent performance standards. Its open-end configuration is favored in installations requiring regular inspection or lubrication access. With its combination of precise dimensions, durable build, and reliable load ratings, the SKF 53408 offers dependable operational life in industrial, construction, and laboratory environments.
