Family specifications and selection conditions
| Product description | SKF double row tapered roller bearings are ready-to-mount units, manufactured with a predetermined axial clearance or preload. TDI design bearings have a double row inner ring and two outer rings that usually have an intermediate ring between them. Their roller sets are arranged face-to-face (X-arrangement). Design variants include features such as a helical groove in the bore, locating slots in the inner ring, or seals on both sides. Also available on request with special sized bore and/or outside diameters, suitable for reworked shafts and housings. |
|---|---|
| Manufacturer features | High radial load carrying capacity • Accommodate axial loads in both directions • Relatively high stiffness • Many variants, including shields, seals, a helical groove in the bore, or locating slots • Ready to mount |
