Description
This needle roller bearing carries radial loads with a compact cross-section, featuring a double row of needle rollers (ZW) for increased load-carrying capacity within a given envelope. Bore diameter is 90.0 mm, outside diameter 125.0 mm, and width 63.0 mm, with a net mass of 2.405 kg. Limiting speed is rated at 4400.0 1/min, with a reference speed of 2550.0 1/min. Radial internal clearance falls within group CN (Group N), suitable for standard fit conditions without excessive preload or play. The standard cage design guides the needle rollers evenly across both rows, supporting stable operation at rated speeds. This bearing type is intended for applications requiring high radial load capacity in a limited radial space, where shaft and housing surfaces serve as the running tracks.
