KGI 22213 CCKW33 Spherical Roller Bearing
The 22213 CCKW33 spherical roller bearing by KGI solves this challenge. Instead of small balls, it features barrel-shaped rollers that provide a much wider contact surface (line contact instead of point contact). This distributes the weight load across a larger area, allowing the bearing to easily handle massive radial loads without crushing or deforming.

Why is the 22213 Bearing a Critical Choice?
In heavy industries, when dealing with extreme weights and continuous vibration, standard components simply cannot keep up. Standard ball bearings rely on point-contact balls that quickly suffer from metal fatigue and fail under the heavy shocks of industrial crushers or long conveyor systems.
The 22213 CCKW33 spherical roller bearing by KGI solves this challenge. Instead of small balls, it features barrel-shaped rollers that provide a much wider contact surface (line contact instead of point contact). This distributes the weight load across a larger area, allowing the bearing to easily handle massive radial loads without crushing or deforming.
In addition to heavy load capacity, its self-aligning feature makes it a powerhouse in harsh environments. Over time, heavy machinery shafts can bend slightly under load or face minor misalignment during setup. KGI's spherical roller bearings compensate for these angles naturally, keeping operations smooth without placing extra stress on the housing.
Tangible Advantages of KGI 22213
- Exceptional Load Capacity: Engineered for continuous pressure, its robust rollers prevent flattening or deformation under extreme weights.
- Vibration Dampening: Built with a sturdy CC-design steel cage, it absorbs severe shocks and prevents heavy impacts from damaging machine frames.
- Extended Service Life: KGI's precision manufacturing minimizes internal friction and heat generation, resulting in a much longer lifespan compared to generic brands.
- Easy Maintenance: The built-in lubrication groove and holes (W33) allow for quick grease replenishment without dismantling the machinery.
How to Read the 22213 CCKW33 Code
Bearing designations might look complicated at first glance, but each segment acts as an exact identification card:
- 222: Indicates the heavy-duty spherical roller bearing series.
- 13: Specifies the size code, which corresponds to a 65mm inner diameter (bore).
- CC: Denotes KGI's optimized internal design featuring two window-type steel cages and a flangeless inner ring for lower friction.
- K (Very Important): Means the bore is tapered (1:12 ratio). This bearing must be mounted using an adapter sleeve rather than directly onto a straight shaft.
- W33: Features an outer ring lubrication groove and three oil/grease holes for effortless maintenance.

Required Accessories for Proper Installation
Because your bearing code includes "K" (tapered bore), purchasing the bearing alone is not enough. To secure it correctly onto a standard 60mm shaft, you need the complete mounting set:
- Adapter Sleeve: Model H 313. Secures the bearing onto a 60mm straight shaft.
- Lock Nut: Model KM 13. The specialized threaded nut used to drive the bearing onto the sleeve.
- Lock Washer: Model MB 13. Secures the nut to prevent loosening from machine vibrations.
*Pro tip: Always purchase the sleeve, nut, and bearing as a matched set to ensure flawless compatibility.
Professional Installation & Maintenance Guide
Many premature bearing failures stem from installation errors rather than hardware defects. Keep these best practices in mind:
- Absolute Cleanliness: Even a single speck of dust or metallic grit on the shaft can disrupt performance. Ensure the mounting area is spotless.
- Correct Nut Tightening: The goal is to seat the bearing snugly onto the sleeve. Do not over-tighten (which can crush the rollers and cause overheating) or under-tighten (which leads to looseness and vibration). Tighten until internal clearance is precisely optimized and rotation remains smooth.
- Regreasing via W33: Inject fresh grease through the outer ring holes until old grease purges out cleanly from the sides.
- Final Locking: Always bend one tab of the MB13 lock washer into a slot on the KM13 nut. Never skip this vital safety step!
Frequently Asked Questions
Q: Can I mount this bearing directly onto a 65mm straight shaft?
No. Because this is a tapered bore ("K") bearing, mounting it directly without an adapter sleeve will result in improper contact and immediate failure. You must use the H 313 adapter sleeve on a 60mm shaft.
Q: Is KGI a reliable choice for heavy industry?
Yes, KGI bearings are manufactured under stringent quality controls, offering exceptional durability and cost-efficiency for industrial replacements.
Q: How much grease should I pack inside?
Fill the internal space of the bearing fully, but pack the surrounding housing cavity only 30% to 50% to allow proper room for heat dissipation and thermal expansion.
