SEISA Gear Couplings - M Series

Supplier: APMS

SEISA Gear Couplings are available from APMS.

Price Guide: POA


  • Torque is fully transmitted even if misalignment of shaft centre or vibration occurs.
  • When misalignment or tilt of connected shafts occurs in operation, it will be automatically adjusted. As no extra load is applied to shaft and bearings, machine is well protected.
  • It is a flexible coupling using crowning gear and has high wear resistance and toughness.
  • As it is separated from centre case, its assembly and removal are easy. Moreover, as it is compact and light, the mounting space can be minimised.
  • Unlike other types of flexible coupling, misalignment of rotation angle between two shafts caused by deflection of coupling cannot happen. It is suitable or the joint of line-shaft, high-speed usage and heavy-load usage.

Features of M Series

The shapes are the same as SS/SE/CC/CE types of gear coupling in JIS B1453. In catalogue, there are 4 types, which are added "GC" before and "M" after JIS code such as GC-SSM, GC-SEM, GC-CCM and GC-CEM, as well as these other types; GC-SMM, GC-SAM, GC-CAM, GC-MV, GC-SV and GC-EEM.

The size number indicates the diameter of coupling case. Bore diameter of shaft is in compliance with JIS, while coupling overall diameter is made more compact. When compared with JIS coupling, therefore, the product is more compact in size and lighter in weight, contributing to your cost savings.

As coupling centre is longer compared to coupling case width, shafts can be easily aligned by moving the coupling case within the range of boss length. This size also makes the teeth inspection easier.

The type GC-SMM for mill motor is in compliance with JEM-1109 standard.

Upright types (GC-MV, GC-SV) and spacer types (GC-SAM, GC-CAM) are standardised with the oil seal cover to prevent oil leakage from key way.

The type MH, whose transmission capacity is increased by heat treatment, is standardised.

The sleeve type GL, which is made more compact, is also available.

GC coupling and its parts are in good stock to be supplied immediately through our sales network. The sleeve type GL, which is made more compact, is also available.
