INA Drawn Cup Needle Roller Bearing, 28mm ID x 35mm OD, 20mm Width, Steel Cage, Open End, HK2820-B

The INA HK2820-B is a premium drawn cup needle roller bearing engineered for applications where minimizing radial section height is critical. With an inside diameter of 28mm, an outside diameter of 35mm, and a 20mm race width, this bearing meets the demands of compact rotary installations.

Constructed with a robust steel cage, it delivers excellent load-bearing capacity and ensures consistent performance in demanding conditions. The drawn cup construction makes the bearing lighter and more space-efficient compared to machined alternatives, allowing for higher speeds and compact assembly, which is particularly useful in automotive transmissions and industrial gearboxes.

An open end design facilitates easy lubrication access and supports higher operational speeds by reducing friction and heat generation. The bearing typically runs directly on the shaft without requiring an inner ring, simplifying shaft design and further reducing system mass and envelope.

The parallel bore type ensures straightforward mounting, while the steel cage maintains needle roller alignment, minimizing wear and extending operational life. Capable of supporting high static and dynamic radial loads, this bearing is ideal for pure radial load scenarios in industrial, manufacturing, agriculture, and mechanical equipment.

Thanks to its precise manufacturing and compact profile, the INA HK2820-B is essential for cost-effective and reliable bearing arrangements in power transmission, motors, and general machinery. Engineers value its ease of installation, ability to permit high speeds, and its suitability for use when the housing bore cannot serve as a raceway.

Typical use cases include industrial gear assemblies, conveyor rollers, packaging machinery, injection molding equipment, and portable power tools where space savings and efficient radial load support are necessary. The open-ended, compact design makes it easy to integrate into tight assemblies, supporting both performance and economic requirements.
