Tapered Roller Bearings - an overview | ScienceDirect Topics

If a radial load is imposed on the bearing an axial load is induced and this must be counteracted by another bearing; it is normal therefore to employ two tapered roller bearings at each end of a shaft system to balance the loads or to use a bearing with two rows of rollers tapered in the opposite directions, as shown in Figure 10.20.

Shielded. Install these bearings for use with coined radial and thrust loads. They are often used in spindle appliions and can be coined with cylindrical roller bearings to better handle radial loads. Double-row bearings handle thrust loads in both directions. Open bearings dissipate heat more efficiently than shielded and sealed bearings.
