SKF KA11950-Z Tapered Roller Bearings

Description

Product Overview

The SKF KA11950-Z tapered roller bearing represents a blend of precision engineering and robust construction, designed to meet the rigorous demands of modern industrial power transmission. Manufactured by SKF USA, a global leader in bearing technology, this component features a tapered cup and cone set that is ground to match, ensuring optimal concentricity and load distribution. With dimensions of 4.56 x 4.56 x 1.25 inches and a weight of 1.92 pounds, the bearing fits compact spaces while delivering the strength required for high‑torque applications. The bearing is greased for lubrication, providing consistent friction reduction and extended service intervals. Its material composition includes high‑grade steel alloys that resist wear, corrosion, and fatigue, delivering a long operational lifespan even under harsh conditions.

Usage

Designed for a wide range of industrial environments, the KA11950-Z excels in applications such as gearboxes, conveyors, and heavy‑duty machinery where precise shaft alignment and high radial and axial load handling are critical. The tapered design efficiently transfers loads between rotating shafts, making it ideal for automotive‑type power trains, mining equipment, and manufacturing lines that require reliable torque transmission. Its grease‑lubricated system simplifies maintenance, allowing technicians to perform routine checks without disassembly of the entire assembly. The bearing’s compact footprint enables integration into space‑constrained designs, while its robust construction ensures performance stability in temperature‑extreme and high‑vibration settings.

FAQ

What type of lubricant should be used with the KA11950-Z bearing?

The bearing is designed for grease lubrication. Use a high‑quality, high‑temperature grease that meets SKF’s specifications to ensure optimal performance and longevity.

Can this bearing be used in high‑temperature environments?

Yes. The steel alloy and grease formulation are selected to operate reliably in elevated temperature ranges typical of industrial machinery, provided the correct grease is applied.

What is the recommended installation procedure?

Install the bearing on a clean, dry shaft with proper fit tolerances. Apply a thin layer of grease to the rolling elements before assembly, and avoid excessive force that could damage the tapered surfaces.

Is there a warranty or after‑sales support for this product?

SKF offers a standard warranty covering material and workmanship defects, along with access to technical support, replacement parts, and engineering assistance through its global service network.

How does the tapered design benefit my equipment?

The tapered geometry efficiently handles combined radial and axial loads, providing smoother power transmission and reducing wear on mating components, which translates to longer equipment life and reduced maintenance costs.
