3. Suffix Description — “A”

Suffix A
According to the INA Catalogue No. 307, the suffix A does not represent a standalone, universally defined technical feature.
Instead:

• It can indicate temporary identification during a transition period, to avoid confusion between similar parts.

• Sometimes it designates bearings or components of the same size and type but with a different internal design.

• It may also be used for special construction features not separately categorized.

• In some cases, it becomes a permanent designation for minor internal variations.

In summary:
Suffix A generally identifies internal or construction variations that do not change the basic form, fit, or function of the bearing.

4. Technical Description

The INA K20X24X13A is a precision needle roller and cage assembly engineered to deliver high radial load capacity in compact mechanical environments. Built with a hardened steel cage and tightly toleranced needle rollers, this assembly provides:

• Smooth, low-friction rotation

• High stiffness and load support

• Excellent performance in limited space applications

Since it does not include inner or outer rings, the housing and shaft must serve as the bearing raceways, requiring adequate hardness and precision.

5. Typical Applications

Automotive Systems

• Transmissions

• Gear shafts

• Clutch hubs

• Differential components

Industrial Machinery

• Gear reducers

• Pumps and compressors

• Electric motors

• Power tools

• Machine tool components

Agricultural & Construction Equipment

• Auxiliary drives

• Compact linkage mechanisms

• High-load rotating joints

General Engineering

Ideal for designs requiring:

• Very high radial load capacity

• Minimal radial space

• Lightweight component construction

• High precision in roller guidance

---

6. Key Advantages

• Compact design with high strength

• Excellent radial load capacity

• Low friction and heat generation

• High-speed capable with correct lubrication

• Durable sheet-steel cage

• OEM-grade INA quality & precision

• Can replace equivalent SKF / FAG / NTN / NSK K-series assemblies

---

7. Usage Recommendations

• Ensure shaft and housing raceways are properly hardened and ground (these act as inner/outer rings).

• Suitable only for radial loads.

• Use lubrication adequate for temperature and speed requirements.

• Ensure correct alignment to maximize service life.

• Verify maximum operating temperature does not exceed 150°C.
