- 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:Taper roller bearings are used on my motor. Serious damage occurred during use. Please help me analyze the possible causes of damage! Thank you
- But it is worth noting that you must control your parts tolerances, affect the tolerance of your variables clearance values are 11, 1 respectively -- bearing outer ring end face of large tolerances; 1 large end bearing inner ring outer ring end face 2 large tolerances; tolerances of bearings; 2 large end face of the inner face of tolerance between the two bearings, bearing; the small ring thickness tolerances; spacer ring tolerances; axial length tolerances; and two bearing diameter tolerances, and the corresponding axis tolerances (same axis but not at the same time processing is considered as two independent variables), consider the last four variables is because of you this application should be tightly matched with the inner ring, it will affect the clearance.
- 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:How does the roller of tapered roller bearings fit in?
- Tapered roller bearings are made up of outer rings, inner rings, rollers, and cages. The outer ring is a single body, and the inner ring, roller and cage are assembled together. They are called inner components. Tapered roller bearings belong to separable bearings, and when installed, the two components (inner and outer rings) can be fitted together.

- 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: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:There is a slot in the inner ring of tapered roller bearings, right? Is the roller in the slot?
- There is a slot in the cone... The ball is placed in the slot. Handan, north, LiAskIs there a gap between the roller and the slot?Can I move axially?Chasing the answerThere is a certain clearance between them. It is not very large. It is caused by the force...
- Q:What are the E and Y values of the 30209 bearings of tapered roller bearings?
- According to its role, it can be divided into the locating shaft shoulder and the transition shaft shoulder.
- Q:What are the conditions for the normal and reverse loading of tapered roller bearings?
- Hello, I'm Camry KMR bearingsTapered roller bearings are generally used in pairs, according to the adjustment, installation and use of different occasions, there are two following arrangement. The 1. suits (outer ring relatively narrow end) corner contact ball bearing or tapered roller bearing pressure center distance is less than two bearing mid span, called dress. The shafting of this method is simple in structure, easy to assemble, disassemble and adjust, but the heating elongation of the shaft will reduce the axial clearance of the bearing and even die.
- Q:What items should be inspected for tapered bearings?
- 2, tapered roller bearings are not allowed to have an electric drill pattern, vibration patterns, yin and Yang face and polished traces, did not promise to emerge supporting construction and obvious measurement traces, did not agree to knock bumps and obvious color difference.3, the name of the whole machine did not promise to have oxide skin.
