3. Suffix Descriptions

Suffix: A

From INA Catalogue No. 307:

• Not a standalone technical designation
• Used for identifying special construction features
• May represent internal design variations
• Often used temporarily during transition phases to avoid confusion
• In some cases becomes a permanent designation for bearings of the same size but with internal differences

Suffix: /0-7

• Indicates micron-level needle sorting
• Ensures needles fall within a precise diameter tolerance band
• Improves load distribution and running smoothness

4. Technical Description

The INA K22X26X10-A-5-7 is a compact and high-performance needle roller and cage assembly engineered for applications requiring high radial load capacity in minimal radial space.

The steel cage accurately guides the needle rollers, enabling:

• Smooth rotation
• Low friction
• High rigidity
• Excellent dimensional stability under load

Since this bearing does not include inner or outer rings, the shaft and housing must act as the raceways. These surfaces must be properly hardened, ground, and finished for optimal operation.

5. Typical Applications

Automotive & Powersports

• Manual transmissions
• Main shaft & countershaft support
• Dirt bikes & off-road motorcycles (including KTM models using 22×26×10 divided needle bearings)
• Clutch and gearbox assemblies

Industrial Machinery

• Gear reducers
• Pumps
• Small motors
• Machine tools
• High-speed mechanisms

Agricultural / Construction Equipment

• Compact, high-load rotating joints
• Auxiliary drive systems

General Engineering

Ideal where:

• High radial load capacity is required
• Space is limited
• Lightweight solutions are needed
• Shaft and housing raceways are already integrated

6. Key Advantages

• High load capacity in a compact size
• Low friction performance
• Stable and reliable at high speeds
• Micron-sorted needles (/0-7) for enhanced precision
• INA premium manufacturing quality
• Compatible replacement for equivalent SKF, NTN, NSK, FAG K22X26X10 series needle cages
