Koyo Drawn Cup Closed End Needle Bearing
Koyo Closed End Drawn Cup Needle Roller Bearings are full complement bearings, where the needles touch each other, maximizing capacity and cost-efficiency with a drawn outer ring. The inward turned lips retain the rollers, ensuring positive radial retention, even when the shaft is repeatedly removed for servicing.
Installation: The installation tool, similar to that used for open end bearings, features a spring-loaded pilot. The pressing tool's angled shoulder should bear against the closed end, holding the bearing on the pilot to start it true in the housing.
Koyo Closed End Drawn Cup Needle Roller Bearing These bearings are full complement needle roller bearings. Full complement means the needles are touching each other. The original drawn cup needle roller bearing, as invented and introduced by Torrington, employs a full complement of rollers. The complement drawn cup bearing combines maximum capacity and low cost with the advantages of the drawn outer ring. The inward turned lips of the cup are used to mechanically retain the full complement of needle rollers to provide positive radial retention of the rollers even though it may be necessary to remove the shaft repeatedly during the servicing of the mechanism employing the bearing. Installation of Closed End Bearings The installation tool combines all the features of the tool used to install open end bearings.But the pilot is spring loaded and is part of the press bed. The angled shoulder of the pressing tool should bear against the closed end, with the bearing held on the pilot, to aid in starting the bearing true in the housing.
