Drawn Cup Needle Bearings

Hartford Technologies is a leading worldwide manufacturer of Drawn Cup Needle Roller Bearings.

These bearings typically consist of three types of components.  The first is a “cup”, which is formed from flat sheet stock via metal stamping and forming operations into a housing which functions as an outer race.  In addition to the cup, there is a cage or separator which is also formed from a metal sheet. Rollers are typically produced from bearing grade chrome steel.

Drawn Cup Needle Roller Bearings are similar to standard roller bearings except for their much smaller diameter-to-length ratio. They are a very popular bearing style due to their small cross-section (distance between ID and OD).  In most cases, a hardened shaft or pin acts as the inner race. Also, rollers are kept parallel to the axis of the shaft by controlling the clearance between the rollers.

Furthermore, the low cross section design of Hartford drawn cup needle bearings provides excellent load carrying capacity, increases power density, and maximizes product life. Thus, minimizing the space required.
