Product Description

Product Description

SKF double row tapered roller bearings are ready-to-mount units, manufactured with a predetermined axial clearance or preload. 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.

• 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
• Ready to mount
