SKF Single Row Tapered Roller Bearing, 20 mm ID, 43 mm OD, Steel Rollers, Sheet Metal Cage, Model 639177

The SKF 639177 is a robust single row Tapered Roller Bearing engineered for industrial mechanical applications where combined radial and axial load handling is essential. Featuring a 20 mm inside diameter and a 43 mm outside diameter, this bearing uses steel rollers and a sheet metal cage, offering high durability and low friction operation.

This bearing design ensures that the projection lines of the raceways intersect at the bearing axis, yielding a true rolling action and reducing frictional moments during operation. The tapered bore type allows the axial load capacity to increase with contact angle, typically between 10° and 30°, providing enhanced load handling performance.

The bearing is constructed with a cone width of 13.25 mm and a cup width of 11 mm, arranged in a single row configuration. Its dynamic and static load ratings are 16.5 kN and 16 kN respectively, which support demanding industrial environments with high load requirements.

With a limiting speed rating of 18,000 rpm and grooved race types, it offers reliable performance for applications requiring rigid bearing adjustments and proper preload settings. SKF’s 639177 bearing is precision manufactured in Germany, adhering to high-quality standards.

Steel rollers with sheet metal cage ensure longevity. Tapered bore type aids in combined radial and axial load capacity. Single row arrangement with cone and cup widths precisely balancing load. High limiting speed rating of 18,000 rpm supports fast-operating machinery.

Grooved raceways optimize true rolling motion and reduce friction. Suitable for heavy-duty industrial, manufacturing, and mechanical applications.

This bearing is ideal for industries such as automotive, heavy machinery, HVAC, manufacturing plants, and other settings requiring dependable bearing solutions. For additional SKF products, explore the Industrial Tools & Equipment category at EnvMart.
