Radial support with needle rollers running directly against a drawn cup outer ring closed on one end, eliminating the need for a separate end cover and keeping grease or oil inside the housing bore on that side. Outside diameter is 47.0 mm, net mass 62.0 g, limiting speed 6600 1/min, reference speed 4900 1/min, manufactured to DIN 618/ISO 3245. The bearing has no seal, so lubricant retention depends on the closed end and the housing design, and access from the open side must be kept clean of contamination during mounting and relubrication. The closed-end design suits applications where the shaft does not pass through and axial space is limited, since the thin-walled drawn cup keeps radial section low while carrying the full needle roller complement. Running without a seal, the bearing needs lubrication through the open end and periodic replenishment appropriate to the given limiting and reference speeds; alignment must keep the shaft within the tolerances typical for needle roller bearings of this type, as no self-aligning capability is provided by the closed cup construction.
