The main feature of these bearings is that the action line of the resulting load through the rollers forms an angle with the geometric axis of the bearing, which is why these bearings are especially suitable for supporting significant combined loads (in radial and axial directions).
Additionally, this design enables an authentic bearing movement without the rollers slipping on the tracks of the external and internal rings.
Another very important variable in this type of bearing is the angle of the contact on the roller tracks, given that based on this, the axial and radial load relations of the application can be compensated (e.g. a greater angle, greater capacity for withstanding axial loads)..
FERSA manufactures these types of bearings in two basic series: Metric and Inches.
When manufacturing bearings, FERSA uses the following International standards:
• The bearing steel complies with ISO 643, ISO 683 – 17, ISO 4967 and ISO 5949 standards.
• Load capabilities are in accordance with ISO 76, ISO 281 and ANSI / AFBMA Std 11 standards.
• The tapered roller bearing tolerances are in accordance with the ISO 492 standard.
• Other dimensions are subject to the ISO 582 standard
• For the metric type tapered roller bearings family, the standards and the series are in accordance with ISO 355, ANSI / AFBMA Std standards 19.2 and ISO 15.
• The inch tapered roller bearings are compliant with ANSI / AFBMA Std. 19.2.
• Bearing designations are subject to the ISO 10317 standard
Typical applications for these bearings are:
• Wheel axle boxes for cars and industrial vehicles
• Vehicle gear boxes, differentials and drive elements
• Public works vehicles (dumpers, excavators, concrete trucks, etc.)
• Train Boogies.
• Machine tool spindles.
