Even for the condition of high load, it fully maintains bearing function either. In addition, with the large grease-storage capacity, it is unnecessary to add grease for a long-term operation.
Since one end of the close-end bearing is sealed, it is suitable for the end of shaft with bearing the small axial sliding force.

Needle Roller Bearing Delivery
The installation of full complement needle roller bearings is usually carried out using auxiliary sleeves. At this time, the auxiliary roller or auxiliary sleeve supports the needle roller to prevent it from falling out, and the journal lifts the needle roller with its own chamfer. As the needle bearing moves slowly inward on the journal, the auxiliary roller Or the auxiliary sleeve will slowly withdraw until it is installed in the working position.
The outer diameter of the auxiliary roller and auxiliary sleeve should be 0.1-0.3mm smaller than the shaft diameter. When installing, first apply grease to the inner surface of the outer ring of the bearing, and put the needle close to the inner surface (a gap should be left when the last needle is inserted).
