Tapered Roller Bearings, according to the row number of rollers, are
defined as single row, double row and four row. The single row tapered roller
bearings clearance should be adjusted when they are mounted. For double row and
four row tapered roller bearings, the clearance can be provided when
assembling them according to national standards, customers don't need to adjust
it.
The tapered roller bearings mainly carry radial, axial combined load with
radial load in the main. The capacity of axial load carrying depends on the
contact angle of outer rings' raceway. The bigger the contact angle is, the
greater the capacity will be.The bearings are mainly used in metallurgy, mining,
rolling mills, automobiles, machines, plastics and other industries.
Combined cylindrical roller/tapered roller bearings, also referred to as
"Kombi" bearings, have been developed by SKF. They comprise two single row
cylindrical roller bearings and one double row
tapered roller bearing, and support radial loads and axial loads separately. The
outer cylindrical roller bearings have high load carrying capacity and are only
subjected to radial loads. The cylindrical rollers are guided between two
integral flanges on the inner ring, whilst the low flange on the inboard side of
the outer ring serves to hold the bearing together until it is mounted. The
tapered roller bearing with steep contact angle positioned between the two
cylindrical roller bearings has two rows of rollers in a face-to-face
arrangement and takes the axial load.
These "Kombi" bearings are employed as work roll bearings on four-high
stands of both hot and cold rolling mills and of cold sheet rolling mills.
Increased demands with respect to the quality and accuracy of the rolled product
as well as further developments in the production process for sheet steel
involving the introduction of contra-bending and axial displacement of the rolls
have meant that work roll bearing loads have been considerably increased. This
means that the four-row tapered roller fag
bearings normally used as work roll bearings can often not meet the
requisite life demands because of the much heavier radial and axial loads
applied.
NSK Taper Roller Bearings can support high radial loads and axial loads in
a single direction. Also available in two and four row versions which are
capable of taking axial loads in either direction. These bearings can be
supplied with high strength cages (optimised designs) and in a range of advanced
special materials for arduous applications.NSK range of Taper Roller Bearings
include: single row taper roller bearings, double row taper roller bearings,
four row taper roller bearings, Molded-OilTM bearings, etc.
Tapered roller koyo bearings are
generally used to support combined load mainly consisting of radial load.Their
cups are separable for easy assembling.During mounting and using,radial
clearance and axial clearance can be adjusted and preloaded mounting can be
made.
