Alves Needle Bearing Universal Joints...

These are the only repairable needle bearing joints on the market. Using the Alves Blue Block design, with modified and special hardened pins, and the highest quality pre-lubricated and sealed needle bearings in the hubs, they are easily repaired on site using the inexpensive, special repair kit available from your local distributor, or from Alves direct. They are physically interchangeable with competing units and provide the precision and reliability required for demanding applications requiring speeds to 6,000 rpm and operating angles to 25°. Greater angular operation can be achieved by utilizing a double universal joint.

Typical Applications Include:

• Outside Diameters from 3/4 inch to 2 inch
  
• Lengths from 2-11/16 inches to 6 inches
  
• Approximate Weights from .31 to 4.5 pounds.
