22217 and 22212 Spherical Roller Bearings: Sizes & Variants
The 22217 spherical roller bearing features an 85 mm bore, 150 mm outside diameter, and 36 mm width, whereas the 22212 spherical roller bearing features a 60 mm bore, 110 mm outside diameter, and 28 mm width. Both belong to the ISO 22200 series engineered for heavy radial loads and shaft misalignment in industrial machinery across Indonesia. However, purchasing staff and workshop technicians cannot rely on outer dimensions alone when sourcing replacements for palm oil mills in Medan or mining conveyors in Balikpapan.
Matching the series number and boundary dimensions is only the first step. Internal design variants such as CA and CC alter cage construction and inner-ring geometry, while the K suffix indicates a 1:12 tapered bore requiring an adapter sleeve. Ordering an incorrect suffix leads to shaft fitment failure, premature friction, and costly machine downtime. HI-TEC ASIA supplies both 22217 and 22212 spherical roller bearings in our premium HI-TEC SILVER tier to keep industrial operations running smoothly.
What are the exact dimensions of 22217 and 22212 spherical roller bearings?
The 22217 spherical roller bearing measures 85 mm bore by 150 mm outer diameter by 36 mm width, while the 22212 measures 60 mm by 110 mm by 28 mm. Both parts belong to the 22200 series of self-aligning rolling-element bearings designed to absorb severe radial loads and moderate axial forces. Understanding these dimensional boundaries helps maintenance teams in Jakarta and Cikarang select the exact replacement for industrial gearboxes, crushers, and heavy pumps.
HI-TEC ASIA stocks these parts in our premium HI-TEC SILVER tier, engineered with high-quality materials for longer service life in demanding environments. Each model is manufactured in specific internal configurations to suit distinct shaft mountings and operational loads. Below is the specification breakdown for both part numbers available in our inventory:
| Part Number | Bore Diameter | Outside Diameter | Width | Series | Available Variants |
|---|---|---|---|---|---|
| 22217 | 85 mm | 150 mm | 36 mm | 22200 | 22217 CA (Open), 22217 CAK (Open), 22217 CC (Open), 22217 CC K (Open), 22217 CCK |
| 22212 | 60 mm | 110 mm | 28 mm | 22200 | 22212 (Open), 22212 CA (Open), 22212 CAK (Open), 22212 CA P6, 22212 CC (Open), 22212 CC K (Open) |
Selecting between 22217 and 22212 depends entirely on shaft diameter and housing size. However, even when two bearings share identical outer dimensions, their internal design suffixes dictate whether they can be installed on a parallel shaft or a tapered sleeve.

What is the difference between CA, CC, and K variants in spherical roller bearings?
The primary difference between CA and CC variants lies in internal cage construction and inner-ring flange design[1][2], while the K suffix designates a 1:12 tapered bore[1][3]. Outer dimensions alone do not determine interchangeability, meaning a 22217 CCK cannot directly replace a straight-bore 22217 CC on a parallel shaft without changing the mounting hardware.
Decoding suffix designations is essential when reviewing engineering drawings or machine spares list. You can read our complete technical guide on how to decode bearing part numbers for full designation rules. The table below outlines key structural criteria distinguishing CA, CC, and K variants within the 22200 series:
| Designation Suffix | Internal / Bore Geometry | Key Structural Characteristics | Application & Mounting Requirement |
|---|---|---|---|
| CA | Straight cylindrical bore | Machined double-prong brass cage with retaining flanges on both inner-ring sides[1][2] | Direct fitment on parallel shafts; heavy-duty industrial machinery |
| CC | Straight cylindrical bore | Two stamped window-type steel cages with a flangeless inner ring and floating guide ring[1][2] | Standard industrial applications requiring reduced internal friction |
| K | 1:12 tapered bore | Tapered internal bore geometry (1 mm diameter change per 12 mm length)[1][3] | Requires an adapter sleeve assembly for cylindrical shaft mounting |
| CAK / CCK | 1:12 tapered bore + CA or CC cage | Combines CA brass or CC steel cage architecture with a 1:12 tapered bore[1][3] | Tapered shaft seats or sleeve-mounted housings in heavy machinery |
A straight-bore bearing such as 22212 CA slides directly onto a smooth 60 mm shaft seat. Conversely, a 22212 CAK features a tapered bore requiring a matching adapter sleeve, such as an H-series sleeve[4], to clamp securely onto a straight shaft. Attempting to force a straight-bore bearing onto a tapered seat - or installing a K-suffix bearing without a sleeve - results in incorrect internal clearance reduction, severe overheating, and mechanical failure[4].
When evaluating choices between heavy-duty designs, engineers often compare tapered vs spherical roller bearings to verify misalignment tolerances. Choosing between adapter vs withdrawal sleeves also depends on machine maintenance accessibility.

Frequently Asked Questions
What are the exact dimensions of 22217 and 22212 spherical roller bearings?
The 22217 spherical roller bearing has an 85 mm bore, 150 mm outer diameter, and 36 mm width. The 22212 spherical roller bearing has a 60 mm bore, 110 mm outer diameter, and 28 mm width. Both belong to the ISO 22200 series.
What is the difference between CA, CC, and K variants in spherical roller bearings?
CA variants feature a heavy-duty machined brass cage with inner-ring retaining flanges, while CC variants utilize stamped steel window cages with a flangeless inner ring. The K suffix indicates a 1:12 tapered bore requiring an adapter sleeve for cylindrical shaft mounting.
Are 22217 and 22212 bearings with the same series number interchangeable?
No, bearings sharing the same series number are not universally interchangeable. A 22217 (85 mm bore) cannot replace a 22212 (60 mm bore) due to different physical sizes. Furthermore, within the same size, a straight-bore CC bearing cannot directly replace a tapered-bore CCK variant without changing shaft hardware.
How do I order 22217 CAK or 22212 CCK bearings from HI-TEC in Indonesia?
You can order HI-TEC SILVER tier 22217 and 22212 bearings in CA, CC, and K configurations by contacting HI-TEC ASIA directly via WhatsApp at +62 823-1004-6527 for immediate pricing and nationwide shipping across Indonesia.
