This needle roller bearing carries full complement of needle rollers in a single row, without an inner ring, machined to DIN 617/ISO 1206. Outside diameter is 80.0 mm, width 25.0 mm, and net mass 0.265 kg. The cage is of standard design, limiting speed reaches 7200 1/min, while the reference speed is set at 4150 1/min. The bearing has no sealing, so lubricant must be supplied and retained by the surrounding housing, and grease or oil relubrication intervals should be planned accordingly. The absence of an inner ring allows the needle rollers to run directly on a hardened and ground shaft, which keeps radial dimensions compact for the given load capacity. Standard cage design guides the needle rollers evenly, supporting reliable operation up to the stated limiting speed.
