SKF taper roller bearings:

SKF Tapered roller bearings have tapered inner and outer ring raceways and tapered rollers. They 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 SKF taper roller bearing axis to provide true rolling and low friction. The axial load carrying capacity of skf tapered roller bearings increases with increasing contact angle a. The size of the angle is related to the calculation factor e: the larger the value of e, the larger the contact angle. skf single row tapered roller bearing is typically adjusted against a second tapered roller bearing. SKF Single row tapered roller bearings are separable i.e. the inner ring with roller and cage assembly (cone) can be mounted separately from the outer ring (cup). The factors that influence SKF bearing performance and service life include but are not limited to the following: Roller end / flange contact area; Raceway profiles; Consistency of profiles and roller size.

SKF tapered roller bearings are fitted with stamped steel cages as standard. Bearings with polymer cages are available on request

High radial and axial loads in one direction
Axial loads in both directions when arranged in pairs
Medium speeds
Small clearance range when bearing pairs are adjusted during mounting
Higher permissible speeds by improved raceway surface roughness
High accuracy pressed steel cage controls roller position resulting in low heat generation and reduced wear properties

Suitable for heavy loads

SKF Taper roller bearings are designed for heavy combined axial and radial loads.

Offer longer life and higher reliability

SKF’s latest state-of-the-art taper roller bearing design is less sensitive to misalignment (up to two minutes of arc) and offers long life, high reliability and low operating temperatures.

CL7C design offers high running accuracy and low friction torque

SKF taper roller bearings operate under full load without any running-in risk or temperature peaks.

Large product assortment

Available in a wide range of sizes including 15 to 320 mm inside diameter

\t Quiet running

The outstanding running and dimensional accuracy allows for extremely silent running conditions.

Application flexibility

Depending on application needs, SKF has the possibility to provide either case-carburized or thru-hardened in some sizes. Typical applications are gearboxes, construction equipment, wheel hubs, and mining bulk conveyors.

Low friction

The optimized roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction.

Long service life

The crowned raceway profiles of basic design bearings and the logarithmic raceway profiles of SKF Explorer bearings optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends , and reduce the sensitivity to misalignment and shaft deflection compared with conventional straight raceway profiles
