Description
Spherical roller bearings use rollers that are thicker in the
middle and thinner at the ends; the race is shaped to match.
Spherical roller bearings can thus adjust to support misaligned
loads. However, spherical rollers are difficult to produce and thus
expensive, and the bearings have higher friction than a comparable
ball bearing since different parts of the spherical rollers run at
different speeds on the rounded race and thus there are opposing
forces along the bearing/race contact.
Features :
1) Spherical roller bearings are principally provided with two rows
of symmetrical spherical rollers and a common sphere raceway in out
ring, the two inner ring raceways are included at an angle to the
bearing axis
2) The bearings have good self-aligning ability and can operate
when the shaft deflection under load or the shaft misaligning in
mounting, and their permissible aligning angle is 1 to 2.5
degree
3) This type of bearings has heavy load carrying capacity and
anti-impact ability, in addition to radial loads, they also can
carry axial loads in two directions
4)In general, this type of bearings permits a low limiting
speed.
Application: paper mill equipment, rolling machines, rolling stock,
shaker screens and general industrial machinery.
