Double Row 22260CACK/W33 Spherical Roller Bearing With Two Grooves For Radial Loading
|Model||Old Model||Boundary dimensions (mm)||Basic load ratings Coa (KN)||Speed ratings (r/min)||Weight (KG)|
Spherical rollers are put between the
spherical raceway on the outer ring and the two grooves on the
inner ring for there bearings. Since the center of the arc raceway
on the outer ring is the same as the center of the whole bearing
arrangement, there bearings are self-aligned and automatically
adjust the bending of the shaft and housing and the eccentricity.
The bearings can carry radial load and axial load in double
directions. The especial radial load carrying capability makes
there bearings suitable for heavy load and shock load carrying.
Spherical roller bearings use cage of MB, CA, CC.
Why Spherical Roller Bearings ?
Spherical roller bearings offer an attractive combination of design
features, which are making them irreplaceable in many demanding
Spherical roller bearings accommodate misalignment between the
shaft and housing
without increasing friction or reducing bearing service life.
Very high load carrying capacity
Optimized internal geometry within the available cross section
provides maximum radial and axial load carrying capacity
Insensitive to misalignment caused by shaft or housing deflections
as a result of heavy
Easily fitted for loads in all directions
The bearings are non-separable and ready to install, having a
choice of mounting methods.
Simplify the application
The favourable design characteristics combined with simplified
mounting procedures enable more efficient and compact machine
Protect against contaminants
Sealed spherical roller bearings are especially suited for bearing
positions where space or cost considerations make external
A contact seal on both sides of the bearing retains the factory
grease fill where it is required: inside the bearing.
Minimized maintenance requirements
Under normal operating conditions, sealed spherical roller bearings
keeping service costs and grease
Radial internal clearance greater than Normal
Radial internal clearance greater than C3
Radial internal clearance greater than C4
