Low Libration Self Aligning Ball Bearing (1209)

Self-aligning ball bearings are mainly used to carry radial loads and light axial loads.
The cages are produced with cold rolling steel strap.
It has two rows of balls and a common concave sphered raceway in the outer ring.
The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing.
It is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected.
Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.
The internal radial clearance of the bearings can be adjusted by adapter sleeve.
VISTA mainly offer 12xx/13xx, 22xx/23xx series self-aligning ball bearings.

self-aligning ball bearings product characteristic:

self-aligning ball bearings has the cylinder bore and the cone bore two kinds of structure, the material that keeps contain steel plate, synthetic resin...etc...Its characteristics is the outside turn rolls a way to present the surface of sphere form, having an au to adjust disposition, can compensate the different heart degree and stalk degree error margin for result in, but it inside, outside turn the opposite inclination degree can not more than 3 degrees.

self-aligning ball bearings structure form:

Take the dust palliative cover and take the deep ditch ball bearings of seal completely the turn assemble have already stuffed with just the right amount of lubrication fat, install the front shouldn't heat to need not clean, either, use and do not need to be lubricate again in the process, adapting movement the temperature - 30 degree go to+120.

main use:
Be applicable to the precise appearance, low noise electrical engineering, automobile, motorcycle and general machine etc., is a machine to use the most extensive bearings in the industry
