single row tapered roller bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The projection lines of the raceways meet at a common point on the bearing axis to provide a true rolling action and therefore low frictional moments during operation. The axial load carrying capacity of tapered roller bearings increases with increasing contact angle α. The size of the contact angle.
 
Single-row conical bearings are demountable, the inner ring with a cage and roller elements and the outer ring are assembled separately. They are manufactured in multiple series. They feature high rigidity, low friction and the ability to transmit high radial and single-direction axial load.
The intensity of the axial load transmitted depends on the size of the contact angle. Through suitable arrangement of a couple of bearings, dual axial load-carrying capacity can be achieved.
 
The single-row conical bearings are manufactured both in metric and inch dimensions.
The bearings are manufactured with normal accuracy, for seating more demanding in terms of accuracy, or seating with higher rpm frequency, bearings with higher running accuracy are used.

Single row tapered roller bearings feature angular raceways of inner and outer ring and a resulting force-transferring contact angle. Due to this, an axial load always induces a radial load and the other way around, which is why tapered roller bearings are always combined with a second bearing. Paired, they can in addition to radial forces also absorb axial and combined forces and are particularly suitable for medium to high speeds. Single row tapered roller bearings can be disassembled which facilitates a separate assembly of inner and outer ring.
 

Standards

 
The general dimensions of the single row tapered roller bearings are standardised by ISO 355 (Tapered roller bearings - Boundary dimensions and series designations) and DIN 720 (Rolling Bearings - Tapered roller bearings). Inch bearings conform to ANSI/ABMA Standard 19.2 (Tapered Roller Bearings - Radial Inch Design).
 

Speed


viiplus distinguishes between kinematic limiting speed nG and thermal reference speed nth. The kinematic limiting speed is a practical mechanical limit value and is based on the mechanical fatigue strength of the rolling bearing as a function of its installation situation and lubrication. The limit speed must not be exceeded even under optimum operating conditions without prior consultation with KRW.
The thermal reference speed represents the equilibrium between the heat generated in the bearing by friction and the heat flow dissipated. It is standardised in DIN ISO 15312 (Rolling bearings - Thermal reference speed).
 

Compensation of Angular Misalignments

 
Single row tapered roller bearings are of limited suitability for compensation of misalignments. The admissible misalignment between inner and outer ring depends on the bearing size, the internal bearing design, the clearance fit, and the acting of forces and moments. Misalignments cause harmful movement of the rolling elements and produce additional stresses in the bearing which reduce its operating life.
