Product Description

Product Description

 

TNA bearings are similar to the TDO, but the inner race narrow faces are extended to abut and eliminate the need for a separate inner race spacer.  Supplied with an in-built clearance to give a standard setting range, these bearings provide a solution for many fixed or floating bearing applications where simplicity of assembly is required.
TNA TDO ,.,.

Size range:

ID 25.400 mm to 1200.150 mm (1.0000 in. to 47.2500 in.)

OD 30.480 mm to 2460.000 mm (1.2000 in. to 96.8504 in.)

 

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.
