2. Category:
• Single-Row tapered roller bearings
• Double-Row tapered roller bearings
• Four-Row tapered roller bearings

We can provide other taper roller bearings with special structures such as sealed taper roller bearing, bearings without inner ring or outer ring etc.
We also design and manufacture other types of taper roller bearings for customers with special requirements.

3. Cages:
Cages of taper roller bearings are pressed steel cages, machined solid cages, glass fiber reinforced polyamide 66 cages and etc. For taper roller bearings with comparable big size and solid cages can be welded with steel stanchions.

4. Specification:
Single-Row tapered roller bearings:
• Inner diameter：20～1270mm
• Outer diameter：40～1465mm
• Width：15～240mm

Double-Row tapered roller bearings
• Inner diameter：38～1560mm
• Outer diameter：70～1800mm
• Width：50～460mm

Four-Row tapered roller bearings
• Inner diameter：130～1600mm

• Width：150～1150mm

5. Applications:
Tapered roller bearings are mainly used in front wheel, back wheel, transmission, differential mechanism,
pinion shaft of car, the main shaft of machine tool, constructional machine, large agricultural machinery, mechanical reduction gear of railway vehicle, and small graduating device of roll neck of rolling mill.
