Drawn Cup Needle Roller Bearings

Drawn Cup Needle Roller Bearings

Drawn cup needle roller bearings are needle bearings that have a small cross-sectional length between the inner diameter (ID) and outer diameter (OD) of the bearing. This makes them the ideal needle bearing for applications with a reduced radial envelope. Drawn cup needle roller bearings consist of a thin-walled outer ring (commonly referred to as a raceway), a cage assembly, and multiple needle rollers.

We can manufacture controlled profile needles and assemble them into thin shells. We currently supply planetary gears, motors, high-performance engine rocker bearings, engine rocker bearings and transfer case bearings. Standard material for cups is AISI 1012, case hardened and tempered HRC 58 min. We also have a full complement of needle rollers that are grease retained or held in place with plastic plug. We can also supply these bearings with plastic cage to retain needles in a thin shell race.

Benefits

• High-Load Bearing Capacity: Our drawn cup needle roller bearing’s small radial envelope allows it to withstand high loads and extreme stresses.
• Excellent Stiffness: Our standard drawn cup design allows for a high volume of needle rollers. The high number of rollers makes this assembly extremely durable, with high strength and excellent stiffness.
• Low Coefficient of Friction: Drawn cup roller bearings reduce the friction between mating surfaces and parts. Aside from their high load-bearing capacity, our needle roller bearings allow for high running speeds.
• Easy-to-Install: These are the ideal needle roller bearings for applications with limited radial space. Their small, compact design and cross-sectional height mean they can easily be installed in tight-fitting areas.
• Simplifies End-User Designs: End-users and customers designing integrated assemblies, engine, and mechanical assemblies can create tight-fitting and compact designs with drawn cup roller bearings.
