40mm Double Row Tapered Roller Bearing , High Precision Tapered Roller Bearings

Taper Roller Bearing Single Row 32008, 40mm Bore

Introdution

Tapered roller bearings mainly bear radial diameter, axial joint load. Load bearing capacity depends on the outer ring raceway angle, angle the greater carrying capacity. These bearings are separable bearings, according to the number of columns bearing rolling elements into single row, double row and four row tapered roller bearings. Single row tapered roller bearing clearance to be user adjusted during installation; double row and four row tapered roller bearing clearance in the factory based on the given user requirements, users do not need to adjust.
Tapered roller bearings have tapered inner and outer ring raceways, tapered rollers are arranged between the two. All conical surface projection lines are a little get together with the bearing axis. This design makes tapered roller bearings particularly suitable for the accommodation of combined (radial and axial) loads. Most of axial load bearing capacity is determined by the contact angle ; greater the angle, the higher the axial load capacity. Angle size to calculate the coefficient e; e value, the greater the contact angle, the bearing axial load greater applicability.

Precision Tapered Roller Bearings

The product adopts CAD design and adopts advanced processing equipment and manufacturing processes including intermediate frequency hot forging and expansion forging, numerical control multi-knife, and profiling turning, heat treatment for protection atmosphere, numerical control grinding, and automatic grinding processing line production; the detection means are complete. Dynamic and non-destructive testing of the product's shape profile, roundness, roughness, vibration, noise, cracks, life, etc., and the effective operation of the TS16949:2002 and ISO9001:2000 quality systems ensure that the entire process quality is controlled.

Feature:

High load carrying capacity
The large number of rollers, which have an optimum conformity with the washer raceways, enables the bearings to accommodate heavy axial and simultaneously acting radial loads.

Amisalignment
Tapered roller bearings are self-aligning and can accommodate misalignment .

Separable design
Tapered roller bearings are separable, making it possible to mount and dismount the housing washer separately from the shaft washer and roller and cage assembly. In addition this facilitates maintenance inspections.

High speed capability
The cage designs and the optimum conformity of the rollers with the washer raceways make the bearings suitable for relatively high speeds.

Long service life
The tapered roller profile reduces edge stresses at the roller/raceway contact.

Low friction
The optimized roller end / flange contact keeps frictional heat at low level, even at high speeds.
