Brass Cage Taper Roller Bearing 32304 20X52X21mm Taper Bore Size
20mm
Introdution
Tapered roller bearings mainly bear radial diameter, axial joint
load. Load bearing capacity depends on the outer ring raceway
angle, angle the greater carrying capacity. These bearings are
separable bearings, according to the number of columns bearing
rolling elements into single row, double row and four row tapered
roller bearings. Single row tapered roller bearing clearance to be
user adjusted during installation; double row and four row tapered
roller bearing clearance in the factory based on the given user
requirements, users do not need to adjust.
Tapered roller bearings have tapered inner and outer ring raceways,
tapered rollers are arranged between the two. All conical surface
projection lines are a little get together with the bearing axis.
This design makes tapered roller bearings particularly suitable for
the accommodation of combined (radial and axial) loads. Most of
axial load bearing capacity is determined by the contact angle ;
greater the angle, the higher the axial load capacity. Angle size
to calculate the coefficient e; e value, the greater the contact
angle, the bearing axial load greater applicability.
Features of roller bearing
The roller and the raceway are in line contact or underline
contact.
Large radial load, carrying capacity and friction coefficient is
small.
Suitable for high speed runing equipment.
nner ring and outer ring can be separated, easy to install and
remove.
