Tapered roller bearing
NSK Taper Roller Bearings support high radial loads and axial loads in a single direction and are available in two and four row versions which are capable of taking axial loads in either direction. Tapers can be supplied with high strength cages (optimized designs) and in a range of advanced special materials for more arduous applications.
Product Features:
Material Technology: Hardened high carbon chromium steel
Advanced Materials: Patented materials including High TF and Super TF are available for more arduous conditions
Patented NSK HR taper roller bearings offer higher load ratings
NSK cage optimized for large taper roller bearings installed in planetary carriers
Segmented plastic cage for inner diameters of more than 1000 mm
Metric and imperial dimensions
Outer diameters up to 2500 mm
Product Benefits:
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.
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 and more.

Type,Structure and Characteristics
Tapered roller bearings are designed such that their conical rollers and raceways are arranged so that all elements of the rollerand race way cones meet at a common apex on the bearing axis.The rolling elements perform the real rotating movement on
the raceway;the synthesized force from the inner and outer ring raceways guides the rollers,pressing them to the large rib on
the inner ring.Metric and inch series are considered standard and both systems are widely used.
The inner ring,rollers and cage can be separated as a unit,or the CONE,from the outer ing,or the CUP.The CUP and cone are
called sub-units,Sub-unit dimension for the nominal cup small inside diameter and bearing contact angle,are standardized
by ISO and ABMA and are compatible between sun-units,Double row and four row bearings are available in addition to single row in addition to single row bearings.
Function
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.
Application
Mainly used in metallurgy, mining, rolling mills, automobiles, machines, plastics and other industries
