Single row tapered roller bearings can withstand radial load and single direction axial load. When the bearing is subjected to a radial load, an axial force will be generated, so when another bearing is required that can withstand the axial force in the opposite direction to balance it.
♦ Separable design of single row tapered roller bearings.
♦ Partial taper design can provide 30 degrees of angle.
♦ The use of special bearing steel, bearing life longer, track surface treatment more precise, more smooth operation.

Width size range： 15mm～240mm
♦ ZWZ metric tapered roller bearings have general grade tolerance, also provide P6X, P6, P5, P4, P2 grade tolerance products, all with GB307.1.
ZWZ single row tapered roller bearings only after the installation of clearance, and after there is another bearing positioned in the opposite direction for adjustment to determine.
Tapered roller bearings generally use steel plate stamping, basket-shaped cage, but the size is larger, also use the car system entity pillar cage.
1. When the bearing outside diameter D ≤ 650mm, the use of steel plate stamping cage, cage after the code are not sign
2. when the bearing outer diameter D>650mm, using steel solid pillar cage, cage after the code does not sign
A: internal structure change
B：Increased contact angle
X：Outline dimensions using international standards
CD：Double outer ring with oil hole or oil groove
TD: Double inner ring with tapered bore.
