  Tapered roller bearings that can withstand challenges and extreme conditions

Tapered roller bearings have tapered inner and outer ring raceways and tapered rollers. Tapered roller bearings can withstand combined loads, that is, radial and axial loads acting simultaneously. The extension of the raceway intersects the same point on the bearing axis, Figure 1) to achieve true rolling, and therefore has a low friction torque during operation. The axial load capacity of tapered roller bearings increases as the contact angle α increases. The size of the contact angle is usually between 10° and 30°. The size of the angle is related to the calculation factor e (→ product table): The larger the value of e, the greater the contact angle.

Bearing characteristics

  Low friction
The optimized roller design on the rib and the surface finish of the rib (Figure 2) can promote the formation of a lubricant film, thereby reducing friction. This also reduces the heat generated by friction and flange wear. In addition, the bearing can better maintain the preload and reduce the noise level during operation.

  long lasting
The basic design of the SKF Explorer bearing. The shape of the logarithmic raceway of the cambered raceway optimizes the load distribution along the contact surface, reduces the peak stress at the roller end (Figure 4), and reduces the sensitivity to misalignment and shaft deflection. Regular straight line (Figure 3).
Improve operational reliability
The optimized surface treatment of the roller and raceway contact surface is conducive to the formation of hydrodynamic lubricant film.

  Consistency of roller profile and dimensions
The manufacturing tolerances and dimensional accuracy of the rollers integrated in SKF tapered roller bearings are so precise that they are almost identical. This provides optimal load distribution to reduce noise and vibration levels, and enables more accurate preloading.

  Rigid bearing applications
A single row tapered roller bearing usually needs to be adjusted together with another tapered roller bearing. By applying preload, rigid bearing applications can be achieved.

  Run-in phase of peak temperature drop 
Tapered roller bearings usually have a running-in period, during which conventionally designed tapered roller bearings experience a lot of friction, resulting in wear. This effect is noted as the peak temperature (Figure 1). Under the premise of accurate bearing installation and lubrication, the use of SKF tapered roller bearings can greatly reduce friction, wear and friction heat.

  Separable and interchangeable 
Depending on the design, tapered roller bearings are separable, and parts of the same size bearings can be completely interchanged. For example, single-row tapered roller bearings are separate (Figure 5), that is, the inner ring (conical inner ring) with roller and cage assembly can be installed separately from the outer ring (conical outer ring). This facilitates installation, disassembly and maintenance inspection procedures.
