Z1 Z2 Z3 ZV1 ZV2 ZV3 Level , Single Row Or Double Row Tapered Roller Bearings
Taper roller bearings have tapered inner and outer ring raceways
between which tapered rollers are arranged. The projection lines of
all the tapered surfaces meet at a common point on the bearing
axis. Their design makes taper roller bearings particularly
suitable for the accommodation of combined (radial and axial)
loads.
Single-row Tapered roller bearings are the most basic and widely
used tapered bearing .And they have tapered inner and outer ring
raceways between which tapered rollers are arranged. This type of
bearings is particularly suitable for carrying of combined (radial
and axial) loads. The axial load carrying capacity of the bearings
is largely determined by the contact angle; the larger contact
angle, the higher the axial load carrying capacity.
It is usually fitted as one of an opposing pair. When assembled,
single-row tapered roller bearings can be set to the required
clearance or preload condition to optimize performance.
Double row tapered roller bearings can carry heavy loads and are
stiff. They are suitable for the accommodation of combined (radial
and axial) loads. And they can locate a shaft axially in both
directions with a given axial clearance or a given preload.
inch taper roller bearings are big demanded in many industries,
like steel industry, mining & construction, automotive, machine
tools, motorcycles, papermaking machinery, pump & compressor,
railways, wind turbines, printing, power tools and so on. Inch
taper roller bearing type like as follows:
