Thrust tapered roller bearings

ZGWRT Full-filling Thrust Tapered Roller Bearings are designed for the pressing part of rolling mills. It doesn't have retainer, and its raceway is full of rollers, so it can bear heavy single axial load.
To meet the special requirement of the rolling mills parts, the top ring of the bearing are machining TTSX and TTSV shape and evenly contact with matching parts, so getting even load.
Because of its bad exchange of rollers, please don't mix mounting the rollers and filling the inner with grease.
The taper rollers (with larger spherical end) of these bearings are guided precisely by the integral flanges of the washers (shaft washer and housing washer) with raceways.

When extended, the design makes the tapered raceway surfaces of the shaft washer and housing washer and the sliding surface of the rollers converge towards to the same single point on the bearing axle.
Single-direction bearings can carry axial load in one direction.
Double-direction bearings can carry axial load in two directions.
The middle washer of double-direction bearings is connected with the shaft, but due to the clearance inside, a sleeve must be used to fix the middle washer in the axial direction.

Applications of single-direction bearings are mainly found in crane hooks and rotational platform for oil drilling, and double-direction bearings in the mill roll necks.
