1.Description:
Spherical roller bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The inner rings with cylindrical or tapered bores.
Types EA, C, CD, CA, these are designed for high load capacity, are available. Types EA, C, and CD have pressed steel cages; and type CA has machined brass cages. Type EA has especially high load capacity, features low torque, and has a high-strength cage.
2.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 axia
2) The bearings have good self-aligning ability and can operate when the shaft deflection under load or 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.
