Tapered Roller Bearing Introduction:
Tapered roller bearings are designed with outer ring, inner ring and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis. Along with metric series bearings, inch series bearings are also available. This type of bearing is suitable for applications that involve heavy or impact loading.
2).Types of taper roller bearing :
1.Single-row tapered roller bearings
2.Double-row tapered roller bearings
3.Four-row tapered roller bearings
4.Double, four-row tapered roller bearings with multi-seal
Taper Roller Bearing Features:
1.With Less coefficient of friction
2.High limiting speed
3.Bear high load can be used in various automobiles
Bearing Application :
The widely use bearing is single row tapered roller bearings.;doule row bearing is widely used for front wheel hub for car, four row tapered roller bearings are used in heavy machinery such as large cold and hot rolling mills.
Such as Medium and large motors, generators, internal combustion engines, gas turbines, machine tool spindles, reduction gears, loading and unloading machinery and various industrial machinery all can be use with taper roller bearing .
We can prodive different type of taper roller bearings ,if you are interested ,pls feel free to contact with me ,here are some KOYO bearing number for your reference:
