Product Description

The MASTERDRIVE Coupling Flange: 12 Coupling Size is a finished bore close-coupled flange designed for industrial power transmission. This metric, round keyed flange has a 10 in outside diameter, a maximum speed of 2,800 RPM, and is constructed from cast iron (MPN 12S-70MM).

Frequently Asked Questions

What is a MASTERDRIVE coupling flange used for?

A MASTERDRIVE coupling flange connects a motor shaft to a driven component in industrial power transmission systems. It is commonly used in pumps, compressors, and conveyors where a close-coupled, rigid connection is required. This cast iron flange handles up to 2,800 RPM and suits metric, round keyed shafts.

What are the specifications of the MASTERDRIVE 12S-70MM coupling flange?

The MASTERDRIVE 12S-70MM is a finished bore close-coupled flange with a 12 coupling size, 10 in outside diameter, and 2,800 RPM max speed. It is made of cast iron, has a metric round keyed bore, and is manufactured by MASTERDRIVE. The part number is 12S-70MM.

Where to buy MASTERDRIVE coupling flanges worldwide?

You can source MASTERDRIVE coupling flanges through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on the 12S-70MM or other MASTERDRIVE parts.

How to select the correct MASTERDRIVE coupling flange?

To select the correct MASTERDRIVE coupling flange, match the coupling size (e.g., 12), shaft diameter, and bore type (metric round keyed) to your application. Verify the max speed rating of 2,800 RPM and ensure the outside diameter of 10 in fits your space. Consult the MASTERDRIVE catalog for torque and misalignment limits.

Used in

Common applications for MASTERDRIVE
Pump drives — MASTERDRIVE finished bore close-coupled flanges (e.g., size 8, cast iron) for direct motor-to-pump shaft connections
Conveyor systems — MASTERDRIVE jaw coupling spiders (e.g., L099/100U) for light-duty power transmission between motor and gearbox
Compressor applications — MASTERDRIVE two-piece sleeve coupling inserts (e.g., 9N) for high-torque, moderate-speed compressor drives
Industrial fans — MASTERDRIVE QD bushed flanges (e.g., size 6, JA bushing) for quick installation on fan shafts
Mixer and agitator drives — MASTERDRIVE metric bore flanges (e.g., size 11, 52mm) for European-standard shaft connections
General power transmission — MASTERDRIVE coupling flanges in sizes 5-11 for connecting rotating equipment with parallel shafts
