Product Description

INA HK1512-AS1-B drawn cup needle roller bearing features a sealed single-row design with 15 mm inside diameter and 21 mm outside diameter, tailored for demanding radial load support in compact and high-speed assemblies.

This bearing incorporates a steel cage that provides excellent dimensional stability even at elevated operating speeds, while the sealed construction effectively retains grease lubrication and minimizes contamination ingress, thus lengthening maintenance intervals.

With a dynamic load rating of 7.9 kN and static load rating of 9.4 kN, the HK1512-AS1-B is capable of enduring sustained radial forces and peak loads during equipment stoppages.

The bearing supports a limiting speed of up to 16,300 rpm, with a recommended maximum grease-lubricated speed of 9,800 rpm for continuous operation, ensuring reliable performance in high-speed textile machinery, power tools, and automotive auxiliary drive applications.

Its slim profile and sealed lubrication make it ideal for compact gearboxes and rotary actuators where radial space is restricted. Precise installation requires a parallel bore and accurate cylindrical shaft to maintain correct radial support and uniform roller distribution.

Sealed design reduces contamination and maintenance frequency. Steel cage supports dimensional stability and heat dissipation. High dynamic and static load ratings ensure reliable performance. Supports high limiting and grease-lubricated speeds.

Tailored for compact and high-speed rotary applications. Ideal in textile machinery, automotive drive components, and power tools. Requires accurate parallel bore shaft for optimal fit. Extends lubrication intervals by retaining grease efficiently.

Designed in the HK series for durability and performance. This product is a dependable choice for industrial, manufacturing, automotive, and mechanical applications demanding thin-section, high-performance needle roller bearings.
