INA Roller Bearing Needle 20 mm ID × 32 mm OD, Steel Cage, Open End, Limiting Speed 18500 rpm, NKI20/20-XL

INA NKI20/20-XL Roller Bearing Needle is engineered for precision and durability in mechanical systems requiring compact form and high load capacity. With an inside diameter of 20 mm and an outside diameter of 32 mm, it is suitable for various industrial configurations while maintaining minimal spatial footprint. The parallel bore type combined with an open end design allows for optimized lubrication access and maintenance throughout its service life.

The bearing features a single-row needle roller configuration, which significantly reduces friction and promotes energy-efficient rotation even under demanding operational conditions. The sheet steel cage is robustly constructed for additional structural integrity and lighter weight, which enhances the overall efficiency and mechanical reliability.

Designed for critical automation systems, electrical machinery, and industrial production environments, the bearing offers a dynamic load rating of 21.4 kN and a static load rating of 30.5 kN. Its fatigue limit load is 5.4 kN, enabling extended operation under repetitive stress. Its high limiting speed of 18500 rpm makes it suitable for high-speed requirements without compromising stability or performance.

Applications include automation, high-performance mechanical assemblies, construction equipment, water treatment systems, manufacturing plants, and commercial machines where reliable load support, compact dimensions, and efficient rotation are essential. The open end type makes routine lubrication straightforward, maintaining smooth operation and longevity.

Features a parallel bore and open end for easy lubrication maintenance. One-row needle roller design decreases friction and enhances efficiency. Manufactured with a durable sheet steel cage for structural strength. Supports high-speed operation with a limiting speed of up to 18500 rpm.
