Product catalog summary

Specifications:
The document provides technical specifications for the Miniature Metal Bellows Coupling I Series MKA. Key parameters include maximum torsional moment, speed, mass of inertia, shaft spring rate, and misalignment tolerances. The couplings are available in various sizes, each with specific dimensions and performance characteristics.

Performance Parameters:

Maximum Torsional Moment: Ranges from 0.4 Nm to 8 Nm.
Speed: Up to 20,000 min^-1 for smaller sizes, and 12,000 min^-1 for larger sizes.
Mass of Inertia: Varies from 0.19 x 10^-6 kgm² to 28 x 10^-6 kgm².
Shaft Spring Rate: Ranges from 50 to 1,300 x 10^-3 Nm/arcmin.
Misalignment Tolerances: Axial ±0.2 to ±0.3 mm, Lateral 0.1 to 0.25 mm.

Material and Construction:

Bellows: Made of stainless steel.
Hubs: Constructed from high-tensile strength aluminum.
Set Screws: Comply with ISO 4029 standards.

Dimensions and Standards:

Dimensions follow DIN ISO 2768 cH standards.
Stock bores D1/D2 are G7 tolerance.
Temperature range: -20°C to +90°C.

Additional Notes:

Cost-effective version available with set screws.
Further bore sizes available upon request.
End faces on the shaft recommended for easier disassembly.

Order Example: MKA 2 - D1 = 6 G7, D2 = 8 G7.
