timken roller bearings

Front faces of single cones and both faces of double cone are extended to contact each other.
Lubrication delivered through three cup spacers.

Two double cones, two single cups and a double cup with a cone spacer and two cup spacers.
Spacers have slots or holes for lubrication.

Slots in the inner race spacer permit lubricant to flow from the bearing chamber to the roll neck.The inner race spacers are hardened to minimize face

Double Row-TDO Tapered Roller Bearings
ID 25.400 mm to 1200.150 mm (1.0000 in. to 47.2500 in.)
OD 30.480 mm to 2460.000 mm (1.2000 in. to 96.8504

Double Row Tapered Roller Bearings
1. RATED LOAD: Cr= 1227 KN, Cor= 2538 KN;
2. AXIAL INTERNAL CLEARANCE: 1.118±0.10 ;

Single row bearings can be "adjusted" to the status that has required clearance(axial clearance) or pre-load for to enable it to achieve optimal perfo

This seating force prevents the rollers from skewing off apex, thereby keeping them positively aligned and located against the cone large rib.

Four-row tapered roller bearings
Their main application is on the roll necks of rolling mill equipment.

Cone spacers are hardened to reduce face wear.
Numbered serially to assure correct installation sequence.
