Hartford Technologies is the world's leading manufacturer of pressed outer ring needle roller bearings.

These bearings usually consist of three types of components. The first is the "cup", which is made of a flat blank through metal stamping and molding operations to form a shell, which is used as an outer ring. In addition to the cup, there is a cage or separator, which is also made of metal plate. The rollers are usually made of bearing grade chromium steel.

Stamped outer ring needle roller bearings are similar to standard roller bearings, but their diameter and length are much smaller. Because of their small cross section (distance between inner diameter and outer diameter), they are a very popular bearing type. In most cases, hardened shafts or pins are used as inner rings. In addition, by controlling the clearance between the rollers, the rollers are parallel to the axis of the shaft.

In addition, the low section design of Hartford stamped outer ring needle roller bearing provides excellent bearing capacity, increases power density and maximizes product life. Therefore, the required space is minimized.

Sealing and stamping outer ring needle roller bearing

Stamped outer ring needle roller bearings are usually open at both ends. One end of the sealed stamping outer ring needle roller bearing is closed (sealed), which is often used for shaft end installation. The seal prevents the migration of lubricant or non-pressurized oil. In addition, this can also prevent pollution of the raceway area.

Stamped outer ring full needle bearing

The stamped outer ring full needle roller bearing is similar to the standard needle roller bearing. The difference is that the design uses as many rollers as possible, and there is no spacing retainer ("cage") separating the rollers. Because of the larger contact area, higher bearing capacity can be achieved.

Application of Stamped Outer Ring Needle Roller Bearing

Hartford Technologies has designed a needle bearing for a leading hospital bed manufacturer to replace the ball bearing and easily meet higher load requirements. This improved design allows easier loading and reduced labor.

Hartford Technologies is a multinational supplier of stamped outer ring needle roller bearings for various industrial applications. These applications include gear box and pulley, valve train, electric tool and shaft support of transfer case.
