Description
Carries radial loads while keeping a compact cross-section, using full needle complement guided by a standard cage. Outside diameter is 85.0 mm and net mass is 0.27 kg, with a limiting speed of 6600.0 1/min and a reference speed of 4450.0 1/min for the NK70/25-XL execution. This needle roller bearing suits mounting positions where radial space is restricted and the shaft seat itself acts as the inner raceway, since no inner ring is included. The standard cage keeps the needles evenly spaced for smooth running up to the stated reference speed, and the given limiting speed marks the mechanical upper bound for the design.
