Datasheet MJT

Product catalog summary

Overview: This document provides technical specifications and details for the MJT and MJT-C series of miniature elastomer couplings used in drive technology. The MJT-C series features a lateral clamping hub, while the MJT series is a cost-effective version with set screws.

Specifications:

Maximum Moment: Ranges from 0.7 Nm to 12.5 Nm depending on the model.
Speed: Maximum speeds range from 13,000 min^-1 to 27,000 min^-1.
Inertia: Values range from 0.21 x 10^-6 kgm² to 6.2 x 10^-6 kgm².
Torsional Stiffness: Ranges from 0.16 x 10^-3 Nm/arcmin to 6.2 x 10^-3 Nm/arcmin.
Shaft Misalignment: Axial misalignment ranges from ±0.6 mm to ±1.0 mm, and lateral misalignment ranges from 0.10 mm to 0.20 mm.
Mass: Approximate mass ranges from 7 g to 48 g.
Tightening Torque of Screws: Ranges from 0.5 Nm to 2.5 Nm.

Dimensions: Dimensions are provided according to DIN ISO 2768 cH standards, with specific measurements for different sizes (14, 20, 30).

Materials:

Hubs: Made of aluminum.
Elastomer Spider: Made of polyurethane, available in blue (B 80-Sh-A) and red (R 98-Sh-A).

Temperature Range: The couplings operate effectively between -20°C and +70°C, with temperature corrections for nominal torques at +30°C, +50°C, and +70°C.

Additional Notes:

Stock bores D1/D2 are available in H8 tolerance, with further bore sizes available upon request.
End faces on the shaft are recommended for easier disassembly of the MJT series.

Order Example: Examples are provided for ordering, specifying the series, size, and bore dimensions.
