TSF Type - Single row bearing with a flange
• The flange is used for axial positioning in the bearing housing.
• Through-hole bearing housing can ensure alignment.
• The flange is not clamped and installed in the usual way.
• The flanged outer ring can be matching with the same series of single row the inner ring.
Following are the common items listed.

• TDO type bearings consist of an integral (double) outer ring and two independent inner rings.
• This kind of bearing structure widens the effective support spacing of the bearing, which is beneficial to bear the load caused by the overturning moment.
• The bearing can be used as a fixed end or a floating end to float in the bearing housing hole to compensate for the thermal expansion of the shaft.
• TDO series bearings usually provide an inner ring spacer, which forms a pre-adjusted assembly with the inner and outer rings.

TS series bearings are the most widely used tapered roller bearings.
• This series of bearing fully cover a variety of metric (ISO and "J" prefix) and inch sizes for selection.
