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.)
Applications:
Heavy-duty gear drives
Various industrial configurations
TDO design bearings have a double row outer ring and two single inner rings that usually have an intermediate ring between them. Their roller sets are arranged back-to-back (O-arrangement), which enables them to accommodate tilting moments. Design variants include features such as a helical groove in the bore or lubrication grooves in the side faces of the bearing rings.
Features:
High radial load carrying capacity
Accommodate axial loads in both directions
Relatively high stiffness
Accommodate tilting moments
Many variants, including a helical groove in the bore or lubrication grooves in the side faces of the bearing rings
