Drawn Cup Needle Bearings

Drawn Cup Needle Bearings are similar to standard roller bearings except
for their much smaller diameter-to-length ratio. In most cases, a hardened
shaft acts as the inner race. By controlling the clearance between the rollers,
rollers are kept parallel to the axis of the shaft.

The low cross section design of Hartford drawn cup needle bearings
provides excellent load carrying capacity, increases power density and
maximizes product life. It also minimizes the space required.

Hartford is a leading worldwide B2B manufacturer of Drawn Cup Needle
Bearings. With TS/ISO certified manufacturing facilities in the US and
China, Hartford supplies customers worldwide quickly and cost-effectively.

Hartford drawn cup needle bearings are widely specified for
applications that include:

• Automotive steering columns
• Outboard Motors
• Power/Hand Tools
• Appliances
• Office Equipment
• Compressors

Hartford significantly improved the torque requirements of a popular
hand tool. By using a Hartford needle bearing, the customer achieved
smoother rotation of the headset and eliminated the binding in
the application.

For a leading manufacturer of hospital beds, Hartford engineered a
needle bearing that replaced a ball bearing, and accommodated higher
loading requirements with ease. This improved design allowed for easier
loading and a reduction in labor.

To meet different application needs, Hartford produces needle bearings
that are sealed, retainer and full complement, and clutch style. In addition
to standard product, Hartford has extensive engineering and manufacturing
capabilities for high quantities of custom needle bearings.

Sealed Drawn Cup Needle Bearings

Drawn cup needle bearings are typically open at both ends.
Sealed Drawn Cup Needle Bearings are closed (sealed) at one end and
are often used for shaft end mounting. The seal keeps the lubricant
or non-pressurized oil from migrating. It also prevents contamination
of the raceway areas.

Standard Sizes (Specifications)
ID: 8mm through 50 mm

Minimum Orders
Up through 25mm: 1,000 qty.
Over 25mm: 500 qty.

Drawn Cup Full Complement
Needle Bearings

Drawn Cup Full Complement Needle Bearings are similar to standard
needle bearings, except the design uses the maximum number of rollers
possible and there is no spacing retainer ("cage") separating the rollers.
This enables higher load-carrying capability due to the greater contact area.

Standard Sizes (Specifications)
ID: 6mm through 60 mm

Minimum Orders
Up through 25mm: 1,000 qty.
Over 25mm: 500 qty.
