SKF Plain Bearing, Polyoxymethylene Material, 45mm Bore, 50mm Outside Diameter, 440 kN Static Load Rating PCM 455040 M

SKF PCM 455040 M plain bearing is engineered for robust shaft support in demanding applications. It has a 45mm bore and 50mm outside diameter, with a 40mm width, providing structural integrity and precise fitment. Constructed from polyoxymethylene (POM) composite, this bearing offers outstanding wear resistance and durability under dynamic mechanical loads.

The plain bearing sustains a static radial load rating of 440 kN, capable of tolerating oscillating, linear, and rotating forces commonly encountered in automotive, textiles manufacturing, and heavy engineering sectors. Internal pores distribute lubricant evenly, minimizing friction and enhancing reliability.

This bearing includes a sintered tin and bronze layer that reduces friction and guarantees smooth running. The steel backing provides impact resistance, while the POM cover layer allows minor misalignments to be tolerated, easing installation and operational accuracy. The convenient relubrication hole facilitates hassle-free maintenance, thereby extending the bearing life significantly.

The modest wall thickness of 2.5mm enables this bearing to fit into compact spaces where installation space is limited. Its design supports efficient load transfer and stable machine performance over extended operating durations.

Typical applications include automotive components, textile machinery, heavy engineering equipment, and other industrial contexts requiring high-quality rotary bearing solutions. SKF’s PCM series combines reliability with ease of maintenance, ensuring smooth operation in various mechanical systems.

The bearing is constructed from durable polyoxymethylene material ensuring wear resistance. It features a 40mm width and a steel backing to withstand impacts effectively. Sintered tin and bronze layers within minimize friction and ensure smooth operation.
