This needle roller bearing carries radial loads within a thin-section drawn cup design, single row, fitted with a cage and open on both ends. Outside diameter is 58.0 mm, width 20.0 mm, and net mass 69.1 g. The limiting speed reaches 5300 1/min, with a reference speed of 4050 1/min. The open-end cup construction means the bearing has no closed end and no integrated sealing, so it must be mounted with a shaft that acts as the inner running surface or paired with a separate inner ring. The cage guides the needle rollers, keeping friction and heat generation low at the stated speed ratings. Without sealing, lubrication and contamination protection must be provided externally, and the housing bore needs to be machined to the tolerance required for correct roller support.
