Factory Price Rolling Mill Bearing 22218 CAK/W33 Self Aligning Roller Bearing
Material
Standard bearing's material is chrome steel (GCr15). It is also called bearing steel. The material can become oxidized and rust after prolonged exposure to humid air, so we filled them with oil or grease to prevend rusting.
Stainless steel bearing material. We usually use 440 stainless steel to produce the bearing. It has stronger rust and corrosion resistance, so generally do not need to add lubricating oil or lubricant. Relative to bearing steel, stainless steel quality is better, the price is more expensive.
To reduce the cost and avoide rusting, buyers can also choose the cheap carbon steel material and zinc coated on bearing surface.
The best fit is the best, not the most expensive.And it mainly depends on where the bearing will be used and buyer's requirement.
22218CA/W33 manufacturer spherical roller bearing
Spherical roller bearings are bearings with drum rollers assembled between an inner ring with two raceways and an outer ring with spherical raceways. Spherical roller bearings have two rows of rollers, which mainly bear radial loads and can also withstand axial loads in either direction. With high radial load capacity, it is especially suitable for work under heavy load or vibration load, but can not bear pure axial load. The raceway of the outer ring of this type of bearing is spherical, so its self-aligning performance is good, and it can compensate the coaxiality error.
