Structure of inch tapered roller bearing 94649/94114CD
Product Description
Tapered roller bearings numbering system
The new five-part number consisting of letters and numbers:
The first part of the prefix letter ---
Prefix letter from one to two letters for the representation of the design conditions bearing level.
EL: ultralight
LL: add light
L: Lightweight
LM: in the light
M: Medium
HM: heavy-duty
H: Heavy
HH: heavier type
EH: super-heavy
T: thrust bearing special
The second part --- angle code
The first digit prefix letters on behalf of the back of the outer contact angle code.
Part III --- Basic Series Number
Second, three or four digits corresponding basic series after a prefix letter.
Part IV --- Part No.
Prefix letter back 5 or 6 digits, the last two digits indicate the actual number of the bearing member.
The outer ring number is represented by 10-19 in any number (including 10 and 19).
Comfort number is represented by 30-49 German any number (including 30 and 49). For any series of bearings, minimum cross section of the first inner ring are 49 numbers.
Part V --- suffix
Single tapered roller bearings have a outer ring, the inner ring and a set of tapered roller cover from the box-type cage into an inner component. Outer and inner components separated according to ISO tapered roller bearings dimensions standards, tapered roller bearing outer or inner components of any standard model and the same model should be able to outer or inner components to achieve international interchangeable. That same model except that the Department of outer dimensions, tolerances must comply with ISO492 (GB307) provided, the inner components of the cone angle, cone diameter components must also comply with the relevant provisions interchangeable.
Typically, single row tapered roller bearing outer ring raceway of the cone angle at 10 ° ~ 19 ° before, be able to withstand the combined effects of bearing the load and radial load. The larger cone angle, the axial load bearing capacity is also greater. Large cone angle of the bearing, post code plus B, cone angle between 25 ° ~ 29 °, it can withstand greater axial load. In addition, single row tapered roller bearings can be resized clearance during installation.
Double row tapered roller bearing outer ring (or inner) as a whole. Two inner (or outer) face similar small, middle spacer, clearance by the spacer thickness is adjusted, it can also be used to adjust the thickness of the spacer double row tapered roller bearings preloaded.
Four-row tapered roller bearings
Timken Bearing TIMKEN four tapered roller bearings are divided into:
Timken TQO (Straight Bore four combination) bearing,
Timken TQOW (with Cone Face Lubrication Slots TQO) Bearings
Timken TQITS (four tapered bore combinations) Bearings
Timken TQITSE (TQIT, with epitaxial inner) bearings.
This kind of bearing has four rows of rollers, it can withstand extreme radial loads and withstand the bidirectional axial load, lower speed limit. On the hot and cold rolling mill which is widely used. Bearing bore and the roll diameter using transition fit. The size of the axial clearance of tapered roller bearing can work in it is great, clearance is too small, the higher temperature; clearance is large, bearing easily damaged, so special attention should be installed in three of the outer ring factory two inner ring, two outer spacer, an inner spacer typing numbers refrain installed wrong.
Four-row tapered roller bearings are one of the main roller bearings, bearing radial and axial load capacity are large, single row radial load capacity of about 3 times, can bear a greater two-way axial load, but lower speed limit. It can limit the shaft (or shell) axial displacement in both directions within the bearing axial clearance range, it can be used as two-way axial positioning. By internal changes spacers to adjust the thickness of the outer ring of the bearing radial and axial clearance.
Four-row tapered roller bearings are mainly used in the hot rolling mill and cold rolling mill work rolls, as well as cogging mill rolls and the like. Due to the requirements of easy handling, usually with a gap with the roll neck. Tapered roller bearings generally use pressed steel cage, larger size, the use of pillars cage.
