Taper roller bearings are widely used in auto, rolling mill, mine, metallurgy, plastic machinery and so on.

Taper roller bearings can endure radial and axial combined load, mainly is radial load. The carrying capacity of bearings is decided by the angle of rolloway nest in outside track, the bigger contact angle, the greater amount of carrying capacity. Consumers need to adjust the clearance of single row taper roller bearings during installing, the clearance of double row and four row taper roller bearings already been booked according to consumers requirement when goods leave factory, so consumer no need to adjust it.
Roller bearings have tapered inside track and outside track rollaway nest, and the taper rollers are ranked between them. All the projection lines of taper surface are all gathering on one point on the axes of bearings. Because of such design, taper roller bearings are especially suitable to endure compound loads, including radial load and axial load. The carrying capacity of axial load of the bearings is mainly decided by the contact angle α, the bigger α, the higher capacity of axial load. The size of angle is showed by calculation factor e, the bigger e is, the bigger contact angle, the higher capacity of axial load. Taper roller bearings usually is divergence type, that is to say the taper inside track component, which is made up by inside track with rollers and retainer, can be installed separately wish taper outside track. |
