Self aligning roller bearing 22217E
Double row rollers, there is a shared spherical raceway in the outer ring and raceways within the inner ring that's inclined to an angle relative to the bearing axis. this inventive creation makes it have automated aligning performance.
Spherical roller bearing 22217 SKF technology
Spherical Roller Bearing mainly used to:
Papermaking machinery, discount gear, railway, Rolling mill roller, Crusher, vibrating screen, printing machinery, woodworking machinery, all sorts of industrial discount gear.
Spherical roller bearings have two rows of symmetrical rollers, a frequent sphered outer ring raceway and two internal ring raceways inclined at an perspective to the bearing axis. The centre factor of the sphere in the outer ring raceway is at the bearing axis. And its features:
1.Accommodate misalignment
Spherical roller bearings are self-aligning like self-aligning ball bearings or CARB bearings.
2.High load carrying capacity
Spherical roller bearings are designed to accommodate each heavy radial masses and axial masses in each directions.
3.Long carrier life
The rollers are manufactured to such tight dimensional and geometrical tolerances that they are virtually same in a curler set. The symmetrical rollers self-adjust, imparting most appropriate load distribution alongside the curler size and collectively with the extraordinary profile forestall stress peaks at the curler ends.
4.Low friction
Self-guiding rollers maintain friction and frictional warmth at low stages ( fig. 5 ). A floating information ring courses unloaded rollers so that they enter the load area in the superior position.
