SKF 22218CCK30-W33 bearing
Spherical roller bearings are self-aligning bearings that are consequently insensitive to misalignment of the shaft, they have two rows of rollers so they are able to carry heavy radial loads, all sizes are available with cylindrical or tapered bores.
Optimized rolling elements:
SKF Explorer rolling elements are manufactured to such close tolerances that they optimize load distribution and provide a smoother running bearing with reduced vibration levels.
SKF Explorer cages have been enhanced to improve guidance of the rolling elements and optimize the effects of the lubricant. These improvements contribute to reduced operating temperatures and improved lubrication to extend grease life and bearing service life.
Advanced surface finish:
The surface topography of SKF Explorer rolling elements and raceways has been optimized, through advanced processes, to create an outstanding combination of properties that reduce friction and enhance the formation of a hydrodynamic film. This maximizes the effects of the lubricant, while reducing heat generation and wear.
Extremely clean steel:
With SKF Explorer bearings, quality starts at the most basic level, with steel that is extremely clean and has the lowest possible number of impurities. By using only steel that is highly homogeneous, SKF bearings have the same material strength throughout, without weak spots. It is this high-purity material that gives SKF Explorer bearings their exceptional strength and durability.
Unique heat treatment process:
SKF has developed a unique heat treatment process to better control the hardness, toughness and dimensional stability of SKF Explorer bearings; All critical factors in applications where operating temperatures are high. The SKF process creates the optimal combination of hardness and dimensional stability. The combination improves wear resistance and provides better control of clearance or preload during operation.
How to expand the lifetime of 22218CCK30-W33 spherical roller bearing:
1. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation.
2. Don't allow strong impact, such as hammer striking, transfer roller pressure
3. Use the accurate installation tool, avoid to use cloth kind and short fibers
4. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer
5. General inspection, such as the surrounding temperature, vibrate, noise inspection
6. Keep bearing cleaning from dirt, dust, pollutant, moisture.
7. Bearing should not be ultra cooled.
Spherical roller bearing design types
spherical roller retainer types EA, C, CD, CA,MB, E,K30, which 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.
An oil groove and holes are provided in the outer ring to supply lubricant and the bearing numbers are suffixed with E4.
To use bearings with oil grooves and holes, it is recommended to provide an oil groove in the housing bore, since the depth of the groove in the bearing is limited.
