- Double row tapered roller bearings
Double row tapered roller bearings can only bear radial load at the same time it can be
subject to bi-directional load. It can be in bearing axial clearance range limit shaft or shell
two-way axial movement.
★Product features
The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surfaces of the
raceways and the roller axes if projected, would all meet at a common point on the main axis of the bearing. The rollers are guided by a
flange on the inner ring. This stops the rollers from sliding out at high speed due to their momentum. The larger the half angles of these
cones the larger the axial force that the bearing can sustain.
★Product application
In many applications tapered roller bearings are used in back-to-back pairs so that axial
forces can be supported equally in either direction.
Pairs of tapered roller bearings are used in:
- car and vehicle wheel
- mining equipment
- moderate speed
- engine motors
- axle systems
- construction
- agriculture
- reducers
- gear box
★Horton tapered roller bearings Basic size
- Single row tapered roller bearings:
Inner ring size: 20mm ~ 1270mm Outer ring size: 40mm ~ 1460mm Width size: 15mm ~ 240mm
- Double row tapered roller bearings:
Inner ring size: 38mm ~ 1560mm Outer ring size: 70mm ~ 1800mm Width size: 50mm ~ 460mm
- Four row tapered roller bearings:
Inner ring size: 130mm ~ 1600mm Outer ring size: 200mm ~ 2000mm Width size: 510mm ~ 1150mm
★Tolerance:
Horton tapered roller bearing with common
tolerance, and also provides P6X, P6, P5, P4,
★Radial clearance
Horton single row tapered roller bearings only
in after installation have clearance, and in
★Cage
Tapered roller bearing general ues the steel plate stamping, basket shape cage, but when the size is bigger, we
also adopts entity cage.
1. Outside diameter D ≤ 650mm, use the steel plate stamping cage, cage postposition without code mark.
2. Outside diameter D > 650 mm, use the steel entity prop cage, cage postposition without code mark.
★Dynamic equivalent load
P = Fr [KN], Fa / Fr ≤ e;
P = 0.4Fr + YFa [KN], Fa / Fr > e.
The single row tapered roller bearings used in pairs (basic physical size can be different), when calculation the
equivalent dynamic load of the bearing, must be included in the radial load cause additional axial force. The single
row tapered roller bearing additional axial force S, can approximate formula: S = Fr / 2y
★Static equivalent load
Single row tapered roller bearings
P0 = 0.5Fr + Y0Fa [KN] P0 < Fr, then P0 = Fr
Double row tapered roller bearings
P = 0Fr + Y1Fa [KN],Fa/Fre ≤ｅ P = 0.67Fr + Y2Fa [KN], Fa/Fre > e
- Q: What is the size of tapered roller bearings 352214?
- Bearing type: tapered roller bearingNew model: 352214Old model: 97514EInternal diameter (mm):70Outside diameter (mm):125Width (mm):75
- Q: What are the conditions for the normal and reverse loading of tapered roller bearings?
- 2. anti loaded (outer ring width relative end) horns contact ball bearing or tapered roller bearing pressure center distance is greater than two at the midpoint of the bearing span, known as anti loading, obviously, axial thermal expansion will increase the axial clearance of bearing. In addition, the structure of reverse loading is more complicated, and it is inconvenient to assemble, disassemble and adjust.Stiffness analysis of positive and negative when the transmission parts of cantilever installation, shaft reverse mounting stiffness ratio of forward shafting high, this is because the distance from the center of pressure bearing with large, maximum bending moment of the bearing force, deformation and axial deformation and are less formal.
- Q: The roller of tapered roller bearings is cylindrical or cylindrical body? Why roller drawing method of drawing section for the rectangular (here I want to add: I have seen the N version, some of the paintings is rectangular, trapezoidal and some paintings, 2 versions, a few of my book is that the proportion is A/2 the roller projection) it indicates that the real roller should be a cylinder or a cylindrical body roller is... What master?
- Tapered roller bearing roller must have certain taper roller and raceway, inside and outside the vertebral vertebral vertex vertex must be of the same point and in the shaft center line (similar to bevel), or when the roller bearing motion reducer and raceway for angular velocity, linear velocity will be the same for different sliding friction and rolling bearing becomes sliding bearing.
- Q: What items should be inspected for tapered bearings?
- 4, tapered roller bearing ring after the whole machine after pickling, there should be no scald, the name of cooperation should not be a pickling visible traces of burns, and no response angle detection.Tapered roller bearing appearance should be smooth, lubrication, no plants, no scratches, no rust and no obviously difference, promised to pressure injury, damage, deformation and defects such as trachoma vipassana.
- Q: Tapered roller bearing: Bearing expert why burned or locked
- Shaft tolerance is relatively small and fine head, the inner shell inside and nose has obvious signs of friction. If there are traces of friction on one side or on both sides of the inner shell, there is an abnormal contact with the inner shell of the bearing and the friction of the inner shell of the bearing.2, the inner shell shell burning marks are not serious, roller black even deformation, generally is the inner shell or casing tolerance, Ambassador bearing gap smaller, and even negative tolerance caused by burning. Or in the maintenance of the bearing selection is not correct, you can use large clearance bearings.3, the shell burned seriously, the inner shell, roller are no obvious changes, you can observe whether the shell has traces of friction. There are traces of friction on the outside, and it can be considered that the tolerance between the bearing shell and the shaft is insufficient, which results in abnormal friction caused by the slipping of the housing. If there are traces of friction on one side or on both sides of the shell, there is an abnormal contact between the component relative to the bearing housing and the bearing housing, and the heat generated by friction will be burned out.
- Q: Taper roller bearings limit speed, according to what to calculate, there is no formula for what?
- There's a manual to find itThe ultimate speed of each model is differentWhich model are you talking about?I can check it for you
- Q: you master good! Ask a question about the use of tapered roller bearings: a mechanism using a double row tapered roller bearings, but did not buy this model, can use two single row tapered roller bearing together instead of double row?
- 3, load and life usually do not vary greatly, this is a personal opinion. I hope I can help you!
- Q: that is to say, the taper head is the face and the back is the back
- The bearings do not have to distinguish between the front and back, and there is no positive and negative said, only in accordance with your actual use to identify the installation direction.
- Q: Tapered roller bearings, 70 in diameter, please tell me the model number

- Q: Turbine turbo rod reduction box, tapered roller bearing at both ends of wormGap measuring method, tapered roller bearingsThe gap is +-0.03, so how do I know the gap is in the range?.
- You can measure the oil gap with a drop bar, that is, a soft drop ruler, which can be purchased without measuring the instrument of the bearing
