Product Description

TNASW/TNASWE

Design attributes:
          

           * Double cup and two single cones
          

           * Internal bearing clearance controlled by extending the front faces of the cones so they contact each other 
         

           * SW variation features chamfers in the bores at the front faces of the two single  cones to form a lubrication groove
          

           * SE variation features a backface rib design to accommodate radial lip seals or stamped closure

Potential applications: sheaves, crane sheaves, oil-field drilling rig sheaves and applications where two-row preset bearings are required
