Koyo Drawn Cup Closed End Needle Bearing

General Installation Requirements

• Drawn cup needle roller bearing must be pressed into its housing.
• An installation tool, like the ones shown, must be used in conjunction with a standard press.
• The bearing must not be hammered into its housing-even in conjunction with the proper assembly mandrel.
• The bearing must not be pressed tightly against a shoulder in the housing.
• If it is necessary to use shouldered housing, depth of the housing bore must be sufficient to ensure the housing shoulder fillet, and the shoulder face, clear the bearing.
• The installation tool must be coaxial with the housing bore.

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.
