It is a rolling-element bearing that permits rotation with low friction,and permits angular misalignment. Typically spherical roller bearings support a rotating shaft in the bore of the inner ring that
may be misaligned in respect to the outer ring. The misalignment is possible due to the spherical internal shape of the outer ring and spherical rollers.Most spherical roller bearing is designed with two rows of rollers,
allowing them to take very heavy radial loads and heavy axial loads. There are also designs with one row of rollers, suitable for lower radial loads and virtually no axial load.
1. Accommodate misalignment Spherical roller bearings can self-aligning like self-aligning ball bearings or CARB bearings
2. High load carrying capacity Spherical roller bearings are designed to accommodate both heavy radial loads and axial loads in both directions.
3. Long service life The rollers are manufactured to such tight dimensional and geometrical tolerances that they are practically identical in a roller set. The symmetrical rollers self-adjust , providing optimal load distribution along the roller length and together with the special profile prevent stress peaks at the roller ends
4. Low friction Self-guiding rollers keep friction and frictional heat at low levels . A floating guide ring guides unloaded rollers so that they enter the load zone in the optimal position.
Application of spherical roller bearing 22230MB:
Spherical roller bearing are used in a variety of applications. Examples include mining, petroleum production, power generation, power transmission, cement processing, aggregate crushing, and metal recycling. Some spherical roller bearings are used in briquetting machines, rubber mixing equipment, rolling mills, rotary dryers, or pulp and paper machinery. Others are used in construction equipment, crushers, electric motors, blowers and fans, gears and drives, plastics machinery, machine tools and traction motors and pumps.
