Spherical Roller Bearings
Spherical roller bearings are available in bore sizes from
25 mm to over 1000 mm. The raceways in the outer ring of
this type bearing are designed with a spherical surface
whose center coincides with the bearing center.
roller bearings are of an improved design having a modified
line contact between the raceways and rollers. This construction
enables very high radial and impact-Ioad capacity. This
bearing type can carry a moderately-high level of bi-directional
axial load and is self-aligning.
This type is used extensively
for large machines where shaft deflection or mounting
error may occur . Spherical roller bearings are used
mill equipment, rolling machines, rolling stock, shaker
screens and general industrial machinery.
and dismounting of Spherical roller bearings is facilitated
through the use of tapered- bore bearings in conjunction
with tapered journals, or adapters or L-withdrawal
Internal clearance can also be precisely set
tapered- bore bearing. Pressed steel cages are
used for small- bore
bearings and machined, high- strength brass or
mild-steel cages are used for bearings with larger bores.
