- Single row Tapered roller bearings
Single row roller bearings can only bear the shaft or shell of a direction of the axial
displacement and a direction of the axial load. So we need the two bearing face to face or
back to back to use.
★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: 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?
- Cylindrical rollers are used only when the raceway is a cylinder.Mechanical drawing clearly stipulates the simplified drawing method of tapered roller bearings. Rollers are drawn into cylinders.
- Q: How does the roller of tapered roller bearings fit in?
- Tapered roller bearings in the production of equipment, it is the first roller and cage assembly, and then into the inner ring, composed of components. Tapered roller bearings as long as the assembly, even if completed the inner ring, because the outer ring is only one ring.I don't know if you'll understand.
- Q: There is a slot in the inner ring of tapered roller bearings, right? Is the roller in the slot?
- Yes.AskIs there a gap between the roller and the slot when the roller is placed in the slot?Chasing the answerNo
- 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: 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?
- Not so simple, please consider the following: 1, clearance of double row bearings generally have clearance design, and no single, you need to set in the middle of every lap, with good clearance, clearance or big or small, or no clearance, you miserable;
- Q: The installation of tapered roller bearings
- 3, bearing ring roller contact surface is cone surface or cylindrical surface?Cone surface, in order to be able to bear both axial force and radial force
- Q: What does "tapered roller bearing" suffix "A" mean?
- Tapered roller bearing suffix AA - angular contact ball bearings with a contact angle of 30 degreesA5 - angular contact ball bearings with a contact angle of 25 degrees
- Q: There are many kinds of tapered roller bearings, because of work requirements, test the external size is qualified, I want to make a test, to test the bearing is qualified, mainly inside and outside diameter and inside and outside the ring height tolerances, diameter ranging from 50mm--80mm, score less, look forward to your help, I thank you there are 322163311532215 main bearings, 313113002
- This is not easy yet. Do you think it's possible to make a standard check instrument yourself?!
- Q: Online cylinder cones are GB/T4663, what do you mean?
- Which size do you want, eldest brother? How do I make so much?GB/T: recommended national standards; GB: mandatory national standards4663: taper roller national standard codeThere is a missing release year later!It should be: GB/T 4663-1994
- Q: What is the 30207 judgment coefficient e of tapered roller bearings?
- What do you need to see for yourself?:Tapered roller bearings: 30207Internal diameter d:35mmOutside diameter D:72mmInner ring height B:17mmOuter ring height C:15mmTotal height (assembly height) T: 18.25mm
