NKS40-XL Needle Roller Bearing

The INA NKS40-XL needle bearing is a precision-engineered component for demanding industrial applications. It features a single-row design with machined outer rings with ribs, a needle roller and cage assembly, as well as removable inner rings. As part of the X-life series, it benefits from optimized raceway surfaces, which enhance load capacity and operational lifespan. The open steel cage construction ensures efficient lubrication and heat dissipation.

Available in two versions: without an inner ring for compact radial dimensions, where a hardened and ground shaft serves as the raceway, suitable for shafts with approximately 40 mm diameter, and with an inner ring for use on shafts that are not designed as bearing raceways, typically for shafts with about 32 mm diameter.

This bearing is designed for high reliability in applications where space constraints and high load capacity are critical, such as in automotive transmissions, industrial machinery, and power tools. It effectively supports radial loads and is intended for use under demanding operating conditions, contributing to reduced maintenance intervals and consistent performance. The design emphasizes durability and precision, meeting industry standards for quality and functionality.
