JMIIJJMIIJ Diaphragm Coupling with Intermediate Shaft (no counterbore), JB/T 9147-1999
JMIIJ Diaphragm Coupling with Intermediate Shaft JUDE
JMIIJ is a diaphragm coupling without counterbore and with a spacer shaft to JB/T 9147-1999: two hubs, two stainless-steel diaphragm packs and a spacer whose length is specified at order. 29 sizes JMIIJ1–JMIIJ29: rated torque 63–180,000 N·m, peak 100–280,000 N·m, bores 20–340 mm, speed up to 9,300 rpm. The spacer raises radial misalignment capacity and allows drop-out removal without moving the machines. Lubrication-free, zero backlash, unaffected by oil and temperature. No direct GOST; counterparts are Rexnord Thomas and KTR Radex-N.
