FAG Needle Roller Bearings Guide

Product Description

The K75×83×40-ZW FAG needle roller and cage assembly consists of two rows of needle rollers and a cage, without separate inner or outer rings. The needle rollers run directly on suitable shaft and housing raceways, providing a very small radial cross-section and high radial load capacity. The ZW double-row design accommodates more rolling elements across a wider bearing arrangement, increasing radial load capacity and rigidity while maintaining a compact radial design. The cage guides and separates the needle rollers, reducing friction and supporting high-speed operation.

The K75×83×40-ZW bearing is suitable for automotive, industrial transmissions, agricultural machinery, construction machinery, material handling, mechanical engineering, and industrial gearboxes. Its double-row structure is well suited to applications requiring higher radial load capacity within limited radial installation space. Meanwhile, the cage-guided design combines high radial load capacity, compact dimensions, and high-speed capability, supporting efficient operation in demanding mechanical systems.
