Single Row Inch Tapered Roller Bearings
Inch tapered roller bearings refer to tapered roller bearings whose dimensions are measured in inches, originating from British and American countries;
Structural form: single row double row four row
The new number consists of five parts of letters and numbers:
*** part --- prefix letters
The prefix letter consists of 1-2 letters and is used to indicate the service level of the designed bearing.
EL: Ultralight
LL: Plus light
L: light
LM: light to medium
M: Medium
HM: Medium and heavy
H: Heavy
HH: Heavy
EH: Extra Heavy
T: Thrust bearing***
***Part---Angle code
The first digit after the prefix letter represents the outer ring contact angle code.
Part 3---Basic Series Numbering
The ***, three or four digits following the prefix letter indicate the corresponding base series.
Part IV---Part Number
The 5th or 6th digit after the prefix letter, that is, the first two digits, indicates the actual number of the bearing part.
The outer ring number is represented by any number from 10 to 19 inclusive.
The inner circle number is represented by any number from 30 to 49 (including 30 and 49). For any series of bearings, the first inner ring of the smallest cross-section is numbered 49.
Part V---Suffix
Single tapered roller bearings have an outer ring, the inner ring and a set of tapered rollers are enclosed by a basket cage to form an inner ring assembly. The outer ring can be separated from the inner ring assembly. According to the ISO tapered roller bearing dimension standard, the outer ring or inner ring assembly of any standard type of tapered roller bearing should be able to achieve international performance with the same type of outer ring or inner ring assembly. exchange. That is to say, the outer ring of the same type must comply with the ISO492 (GB307) regulations in addition to the external dimensions and tolerances, and the cone angle of the inner ring component and the diameter of the component cone must also comply with the relevant regulations for interchangeability.
Usually, the taper angle of the outer ring raceway of a single-row tapered roller bearing is before 10°~19°, which can bear the combined action of bearing radial load and radial load at the same time. The larger the cone angle, the greater the ability to bear the axial load. Bearings with large taper angle, post code plus B, taper angle between 25°~29°, it can bear large axial load. In addition, single row tapered roller bearings can adjust the size of the clearance during installation.
The outer ring (or inner ring) of a double row tapered roller bearing is a single piece. The small end faces of the two inner rings (or outer rings) are similar, and there is a spacer in the middle. The clearance is adjusted by the thickness of the spacer. The thickness of the spacer can also be used to adjust the pre-interference of the double-row tapered roller bearing.
Four row tapered roller bearings
Timken Bearings TIMKEN four-row tapered roller bearings are divided into:
Timken TQO (straight hole four row combination) bearings,
Timken TQOW (with inner ring face lubrication groove TQO) bearings
Timken TQITS (four row tapered bore combination) bearings
Timken TQITSE (TQIT, with extended inner ring) bearings.
This kind of bearing has four rows of rollers, which can bear great radial load, and can bear bidirectional axial load, and the limit speed is low. It is very suitable for various hot and cold rolling mills. The inner diameter of the bearing and the roll diameter adopt a transition fit. The size of the axial clearance has a great relationship with whether the tapered roller bearing can work normally. If the clearance is too small, the temperature rise will be high; when the clearance is large, the bearing is easily damaged, so special attention should be paid to the three outer rings during installation. , The factory typing numbers of two inner rings, two outer spacers, and one inner spacer must not be wrongly installed.
Four-row tapered roller bearing is one of the main roller bearings. This type of bearing has large radial and axial load capacity, and the radial load capacity is about 3 times that of a single row. The limit speed is low. It can limit the axial displacement of the shaft (or housing) in both directions within the range of the bearing axial clearance, so it can be used for bidirectional axial positioning. The diameter and axial clearance of the bearing can be adjusted by changing the thickness of the spacer between the inner and outer rings.
Four-row tapered roller bearings are mainly used for work rolls of hot and cold rolling mills, as well as rolls of billet mills. Due to the requirement of easy loading and unloading, it is usually a clearance fit with the roll neck. Tapered roller bearings generally use a steel stamping cage, and when the size is larger, a strut cage is used.
