Description
This needle roller bearing carries a full complement of needle rollers guided by a TV cage, with an outside diameter of 40.0 mm and a net mass of 60.2 g. It belongs to the light series (XL), which keeps the radial cross-section compact while retaining a high number of rolling elements for the given envelope. The limiting speed is rated at 14800 1/min, with a reference speed of 8500 1/min, giving a working range for continuous operation under adequate lubrication. The TV cage guides the needle rollers axially and reduces friction compared to a full-complement arrangement, allowing steady operation up to the reference speed without excessive heat generation. As an NK-type needle roller bearing, it requires a hardened and ground shaft to serve as the inner raceway, so the mounting surface must be prepared to the tolerance and surface finish needed for direct rolling contact. The compact radial size makes it suitable where installation space is limited but a defined radial load-carrying capacity at the stated speeds is still required.
