Double-row Bearings

TDO.Double row outer ring

This bearing composed by a double row cup and two single cones. The set usually has a spacer to pre-adjust the axial clearance. This structure provide sufficient effective span, therefore, when the incline moment become a major load, often use such bearings. TDO bearings can be used in a fixed position, or do aial movement in the hole of housings, for example to compensate axis expansion.

TDI. Double-row cone bearing

TDIT. Taper-shaped bore double row cone bearing

These two types of bearing composed by a integrative double-row cone and two single-row cups. The whole set usually has a cup spacer to pre-adjust clearance. TDI and TDIT bearings can be used on the fixed end of the swivel bearing housing. If uses the swivel bearing housing, TDI could be used on the free end of the shaft. When be used on the swivel bearings, sometimes need loose installation to facilitate disassembly. TDIT type has a tapered bore, when absolutely needs pressure fit, it heops disassembly, but still require the right order of disassembly.
