INA Needle Roller Bearing 40 mm ID, 50 mm OD, 20 mm Width, Plastic Cage, Parallel Bore, NK40/20-TV-XL

INA NK40/20-TV-XL Needle Roller Bearing is engineered for precision and reliability in demanding mechanical applications. With an inside diameter of 40 mm and an outside diameter of 50 mm, the bearing fits a wide range of shaft sizes and housings. The race width of 20 mm ensures compatibility in compact machinery and assemblies, while its parallel bore type optimizes performance under both dynamic and static load conditions.

Its plastic cage minimizes friction and overall bearing weight, making it suitable for installations where reduced mass is crucial. This cage also contributes to efficient motion and supports longevity by allowing for improved lubrication. The open end type design enables easy access for lubricants, reducing maintenance intervention and promoting extended service life.

The bearing's dynamic load rating of 33.5 kN equips it for operational reliability in automated systems and rotating equipment, while a static load rating of 56 kN supports heavy loads at rest. The single row construction ensures precise motion transfer and reduces complexity, which is especially important in mechanical, automation, and commercial machinery.

With a needle-type design, this bearing is commonly used in automotive drivetrain assemblies, industrial automation equipment, and mechanical systems requiring efficient linear motion transfer. It is also suited for space-constrained and weight-sensitive applications where its compact form factor and plastic cage add value.

Practical uses include installation in manufacturing lines, conveyor mechanisms, robotics, industrial machine tools, and any setup demanding low friction and durable bearing solutions.
