Dealing with very heavy radial and axial loads in applications prone to misalignment or shaft deflections? Meet the challenge with SKF spherical roller bearings, whose high load carrying capacity and ability to accommodate misalignment help you obtain low maintenance costs and long bearing service life. SKF invented this bearing type in 1919 and our range is the widest in the industry today – both open and sealed. Our assortment includes SKF Bearing 21311 E spherical roller bearings designed for many applications, including wind turbine main shafts, continuous casters, vibratory applications and high-speed applications, as well as bearings with Solid Oil, split bearings, SKF Concentric roller bearing units, and, for the harshest operating environments, our SKF three-barrier solution.
Spherical roller bearing with two rollers, the main path a load to bear, but also can withstand axial 1oad in either direction. With high radial 1oad capacity, especially for heavy load or vibration load, but can not withstand pure axial load. The raceway of the bearing outer race is spherical shape, so the self-aligning performance is good,and the coaxial error can be compensated. SKF Bearing 21311 E Spherical roller bearing has two columns of symmetrical spherical roller, the outer ring has a common spherical raceway,inner ring with two raceways inclined at an angle with the-axis of the bearing, has good aligning performance, the axial force bending or the installation of the bearing can be used not concentric, concentric tone with the size of bearing series vary. General allowed aligning angle is1 2.5 degrees, the bearing capacity is 1arge, the axial load can bear radial 1oad and the outer bearing can bear bidirectional effects, has good anti impact ability,
general spherical roller bearings allow 1ow working speed.
Spherical roller bearing is divided into symmetrical and non symmetrical spherical roller spherical roller two different structure according to roller shape,non symmetrical SKF Bearing 21311 E spherical roller bearing is the early products,mainly for the host service, the new design is rarely used host symmetrical spherical roller bearing, through the comprehensive improvement of internal structure design and parameter opt imitation, compared with early production of spherical roller bearings can withstand axial load.Spherical roller bearings are divided into: cylindrical .hole, tapered bore.
Hole taper cone respectively of 1:12 rear code for K
spherical roller bearing (153000 or 113000)
and the 1:30
rear code for K30 spherical roller bearing. When the bearings are matched with the conical shaft, the inner ring moves along the axial direction, so that the radial clearance of the bearing can be adjusted.
