Product Description

The INA NK85/35-XL is a high-performance needle roller bearing engineered to deliver exceptional radial load capacity in a compact form factor. With an 85 mm inner diameter and a 35 mm race width, this bearing is suitable for various industrial and mechanical assemblies that demand reliable rotation and space optimization. Its open end design allows straightforward maintenance and efficient lubrication access, contributing to prolonged operational lifespan and minimal downtimes.

Designed for applications where drawn cup needle roller bearings are insufficient and the higher load capacities of cylindrical Roller Bearings are not yet required, this bearing fills a critical niche in mechanical systems. The parallel bore ensures a precise and secure fit on the shaft, reducing wear and maximizing consistency in performance over time. Given its capability to support only radial loads, it excels as a non-locating bearing, accommodating the necessary axial displacement between shaft and housing within the machinery.

The NK85/35-XL can support dynamic loads up to 111 kN and static loads up to 193 kN, with the needle roller construction providing an optimal balance between strength and compactness. This enables the bearing to perform at high speeds despite its line contact design, and to compensate for slight misalignments between shaft and housing. The open design also helps in reducing overall friction and allows for easy inspection during scheduled maintenance checks.

INA is recognized globally for precision engineering in bearings, and this model is no exception, providing consistent performance for critical rotating equipment in industries such as manufacturing, fluid power, mechanical machinery, conveyors, HVAC systems, and laboratory setups. Its specifically engineered housing and raceways contribute to a durable, compact, and cost-effective solution under heavy radial loading.

This needle roller bearing is ideal for use in demanding positions within industrial gearboxes, heavy-duty pumps, automotive systems, and machine tools. The product ensures minimal radial play and maximum operational efficiency, supporting long-term, trouble-free operation across a wide range of environments.
