Drawn Cup Needle Bearings

Hartford Technologies' line of Drawn Cup Needle Bearings consist of a stamped outer shell, cage and needle rollers. Drawn Cup Needle Bearings are similar to standard roller bearings, except for a smaller diameter-to-length ratio, which allows them to fit tight envelopes. By controlling the clearance between the rollers, rollers are kept parallel to the axis of the shaft. The major advantage that needle bearings offer is that they operate with rolling motion, rather than sliding motion. As a result, friction is less, the torque required to rotate the shaft is lowered, less heat is generated and lubrication is simplified. The bearing wear is substantially reduced.

Hartford Drawn Cup Needle Bearings have a low cross section design and are manufactured in chrome steel and low carbon steel in sizes as small as 3 mm I.D by 6.5mm O.D. The bearings are typically open at both ends and Sealed Drawn Cup Needle Bearings are sealed at one end and are often used for shaft end mounting. The seal keeps the lubricant or non-pressurized oil from migrating, and prevents contamination of the raceway areas. Material options for Hartford bearings include chrome steel and low carbon steel; bearings can be supplied in lots as small as 500 pieces.

Applications are diverse and range from 2-stroke engines to towel dispensers. Other applications include automotive steering columns, outboard motors, power tools, appliances, office equipment and air compressors.
