This needle roller bearing carries radial loads without an inner ring, requiring a hardened and ground shaft seat to serve as the running surface. The RNA6914-ZW-XL has an outside diameter of 100.0 mm and a net mass of 851.35 g, and is built with two rows of rollers (ZW) held in a standard cage. The limiting speed is 5700 1/min, with a reference speed of 3450 1/min, values that define the thermal and mechanical speed limits under standard operating conditions. The bearing has no seals, so lubrication and contamination protection must be provided by the surrounding housing design. The absence of an inner ring keeps radial section height low while the double-row configuration increases radial load capacity compared to a single-row design of the same width. The standard cage guides the needle rollers evenly, maintaining consistent spacing under load and supporting smooth operation up to the stated speed limits.
