The 2220K is a premium double-row self-aligning ball bearing measuring 100 mm (ID) × 180 mm (OD) × 46 mm (Width). Designed with a 1:12 tapered bore, it features a common spherical raceway in the outer ring that naturally compensates for shaft misalignments and deflections. Manufactured from high-quality GCr15 chrome steel and fitted with a durable steel cage, it offers extremely low friction and a long service life. We supply B2B manufacturers with OEM customized services, custom brand marking, and secure original packaging.
The 2220K Self-Aligning Ball Bearing is engineered to operate efficiently even when the alignment of the shaft and housing is difficult to establish or when the shaft bends during operation. The "K" suffix indicates that the bearing features a tapered bore (1:12 taper), meaning it is designed to be mounted directly onto a tapered shaft or mounted to a cylindrical shaft using an adapter sleeve. Of all rolling-element bearings, self-aligning ball bearings produce the lowest friction, allowing them to run cooler at high speeds.
Ensure proper equipment integration by referencing the precise dimensions below.
Item | Specification |
|---|---|
Model Number | 2220K |
Inner Diameter (d) | 100 mm |
Outer Diameter (D) | 180 mm |
Width (B) | 46 mm |
Bore Type | Tapered (1:12) |
Bearing Material | Chrome Steel (GCr15) |
Cage Material | Steel Cage (Customizable) |
Dynamic Load Rating | High radial load capacity (e.g., up to 21,938 lbf) |
Operating Temperature | -30°C to +110°C |
(Note: If your application requires a 110 mm inner diameter, please request the 2222K bearing, which measures 110x200x53 mm.)
The 2220K is a high-quality rotary component chosen by OEMs for its resilience in demanding environments:
Misalignment Compensation: The dual rows of balls rotate freely within a shared spherical outer raceway, effortlessly absorbing structural bending and mounting errors without increasing friction.
High-Speed Durability: The combination of low-friction rolling elements and an unsealed (open) design prevents excess frictional heat buildup, enabling reliable high-speed operation.
Long Life Material: Forged from GCr15 chrome steel, the rings and balls exhibit superior resistance to wear and heat, maintaining stable load capacities over an extended lifecycle.
Because it effectively neutralizes vibration and shaft deflection, the 2220K is widely used in heavy industrial sectors:
Paper manufacturing and textile mills.
Heavy rolling mills and mining equipment.
Automotive drive systems, tractors, and agricultural machinery.
Construction machinery and large industrial fans.
We understand the rigorous demands of global mechanical engineering and wholesale supply chains.
OEM Services: We offer completely customizable branding, allowing your company's logo or specific part numbers to be marked on the bearings.
Packaging: Bearings are delivered in original factory packaging or can be packed in custom-branded boxes to fit your retail distribution needs.
Support & Ordering: Our engineering team can provide matching adapter sleeves (e.g., H320) if required for mounting. Contact our sales team for bulk pricing and lead times.
Q1: What does the "K" mean in 2220K?
A: The "K" indicates that the bearing has a tapered bore (a 1:12 slope). It must be mounted onto a shaft that is specifically machined with a matching taper, or mounted onto a standard straight shaft using a conical adapter sleeve (like an H-series sleeve).
Q2: Can this bearing handle axial (thrust) loads?
A: Self-aligning ball bearings are primarily designed to handle heavy radial loads. However, they can support light to moderate axial loads in both directions.
Q3: How do I lubricate the 2220K bearing?
A: The standard 2220K has an "open" enclosure (no seals), meaning it allows for easy and continuous oil or grease lubrication from the machine's internal housing.
