22210 CA vs 22210 CC vs 22210 K Bearing Suffix Meaning
The 22210 bearing suffix meaning decodes critical internal geometry differences, including cage material, internal guide structure, and shaft mounting style. Every HI-TEC SILVER 22210 spherical roller bearing has a 50 mm bore, 90 mm outside diameter, and 23 mm width, while suffixes CA, CC, and K specify cage design and bore taper. Understanding these suffix codes prevents catastrophic assembly failures and ensures optimal operational lifespans for machinery across Pakistan.
Buyers often assume that all 22210 series bearings are interchangeable because they share identical external boundary dimensions. However, operating a stamped steel cage under severe shock loads or attempting to fit a straight shaft onto a tapered bore leads to immediate downtime. This technical guide breaks down each 22210 suffix variant so maintenance teams and procurement engineers can select the exact bearing for their machinery.
What are the exact dimensions and specs of a 22210 spherical roller bearing?
Every HI-TEC SILVER 22210 spherical roller bearing features a 50 mm bore, a 90 mm outside diameter, and a 23 mm width[1]. While these ISO boundary dimensions remain constant across the entire 22200 series family, spherical roller bearings sharing the 22210 series number are not universally interchangeable, as internal geometry and mounting taper dictate exact machinery fitment. Selecting the correct variant requires evaluating whether the application needs a straight cylindrical bore or a tapered bore for adapter sleeve assembly, alongside the appropriate cage material.
HI-TEC BEARINGS stocks five distinct open variants in the premium HI-TEC SILVER product line to cover diverse industrial applications across Pakistan. The table below outlines the core structural differences across all five variants:
| Part Variant | Bore Type | Bore Diameter | Outside Diameter | Width | Cage Material & Construction |
|---|---|---|---|---|---|
| 22210 CA (Open) | Straight | 50 mm[1] | 90 mm[1] | 23 mm[1] | Machined Brass (One-piece rigid design) |
| 22210 CAK (Open) | Tapered (1:12)[1] | 50 mm[1] | 90 mm[1] | 23 mm[1] | Machined Brass (One-piece rigid design) |
| 22210 CC (Open) | Straight | 50 mm[1] | 90 mm[1] | 23 mm[1] | Stamped Steel (Floating guide ring) |
| 22210 CC K (Open) | Tapered (1:12)[1] | 50 mm[1] | 90 mm[1] | 23 mm[1] | Stamped Steel (Floating guide ring) |
| 22210 K (Open) | Tapered (1:12)[1] | 50 mm[1] | 90 mm[1] | 23 mm[1] | Standard Manufacturer Spec (Tapered) |
Verifying both the suffix and mounting setup ensures smooth installation and avoids premature dynamic fatigue during high-load operations.

What is the difference between 22210 CA and 22210 CC cage designs?
The CA suffix indicates a 22210 bearing with a one-piece precision-machined brass cage, whereas CC designates a stamped steel cage with floating guide rings for higher load capacity. Machined brass CA cages offer high mechanical strength and structural rigidity, making them ideal for heavy shock loads, high vibration, and harsh operating conditions. Conversely, CC cages use two independent stamped steel pockets guided directly by the rolling elements, reducing internal friction and overall cage mass.
Selecting between CA and CC depends on whether the application requires the rigidity of brass or the enhanced load distribution of dual steel cages. Evaluating specific operating criteria helps engineers choose the right variant within our broader spherical roller bearings selection:
| Operating Condition | Recommended Suffix | Engineering Selection Reason |
|---|---|---|
| Heavy Shock & Vibration | 22210 CA | Machined brass cage resists impact deformation and fatigue |
| High Speed & Lower Inertia | 22210 CC | Stamped steel cage reduces mass, sliding friction, and heat build-up |
| Contaminated Lubrication | 22210 CA | Brass material handles wear particles without catastrophic cage fracture |
| Maximum Load Distribution | 22210 CC | Floating guide ring allows independent roller guidance under heavy radial loads |
Matching the cage construction to machine stress parameters ensures optimal performance under tough operating environments.
What does the K suffix mean on a 22210 bearing?
A 22210 K bearing features a 1:12 tapered bore requiring an adapter sleeve for shaft mounting, making it distinct from straight-bore 22210 CA or CC variants[1]. The 1:12 taper ratio means the inner ring bore expands by 1 mm in diameter for every 12 mm of axial length[1]. This conical inner profile allows plant engineers to mount the bearing onto smooth cylindrical shafts using an adapter sleeve (such as an H210 sleeve) or directly onto a tapered shaft journal.
When a part number combines suffixes - such as 22210 CAK or 22210 CC K - it merges the internal cage architecture with the tapered bore design. Mounting a tapered bearing allows technicians to achieve precise radial internal clearance reduction by driving the bearing up the sleeve taper during assembly.

Frequently Asked Questions
What is the difference between 22210 CA, 22210 CC, and 22210 K bearings?
The 22210 CA features a one-piece machined brass cage designed for shock resistance, while the 22210 CC uses a stamped steel cage with a floating guide ring for reduced friction and higher speed ratings. The 22210 K specifies a 1:12 tapered bore for adapter sleeve mounting rather than a straight cylindrical shaft.
What are the exact dimensions of a 22210 spherical roller bearing?
All 22210 series spherical roller bearings share identical boundary dimensions: a 50 mm bore diameter, a 90 mm outside diameter, and a 23 mm width. However, internal cage construction and bore taper (straight vs. 1:12 tapered) vary based on the specific suffix code.
What does the K suffix mean on a 22210 bearing?
The K suffix indicates that the bearing has a 1:12 tapered bore. This design allows the bearing to be mounted on smooth shafts using an adapter sleeve or directly onto a tapered shaft seating, simplifying installation and axial clearance adjustment.
Are all 22210 series spherical roller bearings interchangeable?
No, 22210 series bearings are not universally interchangeable. While their outer dimensions (50x90x23 mm) match, variations in bore taper (straight vs. K tapered bore) and cage material (brass CA vs. steel CC) dictate exact mechanical fitment and operating limits.
