Wghb NTN K/K30/M/2RS/TV Cylindrical Hole and Conical Hole Retainer 1204 1307 2308 1217 Self-Aligning Ball Bearing

Self Aligning Ball Bearings

Self aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. Self aligning ball bearings are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection or housing deformations. Self aligning ball bearings are suitable for applications where the shaft relative to the housing bore is prone to angular misalignments. Under normal loads, depending on the dimensional series, the maximum permissible angular misalignment is approximately 2°to 4°. These bearings are available in open and sealed versions and inner rings with a cylindrical or tapered bore.

There are two types of structures for self-aligning ball bearings: cylindrical hole and conical hole. The material of the retainer includes steel plate, synthetic resin, etc. Its characteristic is that the outer ring raceway is spherical in shape and has automatic centering, which can compensate for errors caused by different centricity and shaft deflection, but the relative inclination of the inner and outer rings should not exceed 3 degrees. 
self-aligning ball bearing with two rows of ballspivoting inner ring, misalignments and shaft deflections can be compensatedsuitable for high radial loads and light axial loads in both directions

cage material: sheet steel, high load-bearing capacity and high strength; suitable for continuous high temperatures
seal: open (without seal); for higher speeds than with sealed ball bearings and easy relubrication.good fixed bearing property, but can also be used as a floating bearing, each in both directions

Product features: mainly bear radial load, at the same time can bear small axial load. The axial displacement of the shaft (shell) is limited within the clearance limit, with automatic self-aligning performance, allowing the normal work under the condition of relatively small inclination inside and outside, suitable for supporting seat holes can not strictly ensure the coaxiality of the parts.

The type of bearing component materials used will determine the life span, reliability and performance of the bearings. However, there are many factors affecting the performance of the bearings which include the selection of the load carrying capacity, the rolling contact conditions, and the cleanliness of the operating environment and the dimensional stability of the bearing components.

Application:
Self aligning ball bearings are suitable for bearing heavy loads and impact loads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mines, petroleum, papermaking, cement, sugar squeezing and other industries, as well as general machinery
