THRUST ROLLER BEARINGS
2. TAPER ROLLER THRUST BEARINGS
Thrust tapered roller bearings are equipped with cone-shaped rollers (the big end is spherical), and the rollers are accurately guided by the ribs of the raceway ring (shaft ring, seat ring). The design makes the vertices of the conical surfaces of the shaft ring and the seat ring, the raceway surface and the roller rolling surface intersect at a point on the center line of the bearing.
Product category
The Tapered Roller Thrust Bearings currently produced by ZWZ can be roughly divided into the following structural types：
Single Direction Tapered Roller Thrust Bearings
Double Direction Tapered Roller Thrust Bearings
Screw down Tapered Roller Thrust Bearings
Tolerance
The tolerance of ZWZ thrust tapered roller bearings is implemented in accordance with GB/T 307.4.ZWZ can provide products of general grade, 6, 5, and 4 grade.
Cage
ZWZ thrust tapered roller bearings mostly use brass solid cages or other turned solid cages. When a brass solid cage is used, the rear code of the cage is not marked, and the other marks are corresponding to the rear code.

Bearing Code
X1 Outer diameter is non-standard
X2 Width (height) is not standard
X3 Outer diameter, width (height) non-standard (standard inner diameter)
X4 The inner diameter is rounded off for non-standard bearings. When the inner diameter is a non-integer and has two or more decimal places, X4 is used to indicate rounding.
V Full complement of rolling elements (without cage)
/HG Rings and rolling elements or only the rings are made of other bearing steel（/HG-5GrMnMo；/HG1-55SiMoVA；/HG2-GCr18Mo；/HG3-42CrMo；/HG4-GCr15SiMn）
/W 281 Means special bearing for rolling mill (execute Q/W Z.J 14281 standard)
Q1 Aluminum iron manganese bronze
F1 Carbon steel
F3 Ductile iron
/HA Ring rolling element and cage or only the ring and rolling element are made of vacuum smelted bearing steel
/HC Rings and rolling elements or only the rings or only the rolling elements are made of carburized steel（/HC-20Cr2Ni4A；/HC1-20Cr2Mn2MoA；/HC2-15Mn；/HC3-G20CrMo）
M Brass solid cage
YA2 There is a difference between the bore of the inner ring and the standard design
YA3 The end face of the bearing ring is different from the standard design
YAD Bearings of the same type, with more than two changes in structure at the same time
