Thrust Roller Bearings

Tapered 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.

Tolerance

The tolerance of Sinofou 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.

Radial Clearance

Cage

Sinofou 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.

Code description

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
