Description
This needle roller bearing carries needle rollers guided in a drawn cup with one closed end, providing a two-row arrangement in a single housing bore of 32.0 mm outside diameter. The design corresponds to DIN 618/ISO 3245. Net mass is 67.486 g, with a limiting speed of 10200.0 1/min and a reference speed of 7300.0 1/min. The closed end blocks the bore from one side, so the housing seat needs only a through-hole on the open side, simplifying installation and preventing dirt ingress from the closed end during operation. The two-row design increases radial load capacity compared to a single-row cup within the same envelope, while the thin-walled drawn construction keeps radial space requirements low. The stated limiting and reference speeds define the operating range for continuous use, and shaft fit tolerance should be selected to match the running clearance intended for this cup type.
