Features
Outstanding Durability
The coupling performs outstanding durability with
the torque on the coupling shared with the surfacehardened teeth of the sprockets and the powerful
roller chains that engage with the teeth.
Easy Coupling and Decoupling
Both shafts can be easily coupled or decoupled
with a single joint pin inserted into or extracted
from the roller chains.
Absorption of Large Misalignment
The clearances between the chains and sprockets
and between chain components absorb the great
positional misalignment of both shafts.
Models in a Wide Variety
A total of 24 models including 15 models
conforming to JIS and 9 other models are
standardized.
(Roller chain shaft joint: Conforms to JIS B
1456-1989)

(General)
● Install a safety cover and prevent access to any rotating parts: otherwise injury may occur. Set a safety mechanism to stop the
rotating parts when the cover is lifted.
● Transporting, installing, operating, maintaining or inspecting must be carried out by skilled and professional engineers to avoid
mis-handling and hazardous situations.
● When coupling is used with vehicles that carry human, use a device to protect the vehicle: otherwise, accidents and damage
may occur.
● When the coupling is used for an elevator, install a safety device on the elevator in order to prevent it from falling, which can
cause damage and accidents resulting in death or injury.
(Unpacking upon delivery)
● If delivered in a wooden case, unpack with care. Sharp nails may cause injury.
(Additional machining)
● Never modify the coupling; the quality or function of the product may decrease and break or damage the machine or injure the
operator.
(Transportation)
● Never step under the product when it is being elevated for transportation: otherwise, either the poduct or load may fall, causing
accidents resulting in death or injury.
(Installation)
● Wear appropriate clothing and safety gear (safety goggles, gloves, shoes, etc.).
● Make sure the power is switched off, and the machine is completely stopped before installing. Take caution so that the power
does not reconnect accidentally.
● Make sure to tighten and apply sufficient amount of anti-loosening agent to the hexagonal socket head cap screws.
(Operation)
● Avoid contact with any rotating parts ( coupling, shaft, etc. ) during operations. Rotating parts can catch approaching objects
and cause serious injuries.
(Maintenance and inspection)
● Avoid contact with any rotating parts ( coupling, shaft, etc. ) during maintenance and inspection. Rotating parts can catch
approaching objects and cause serious injuries.
● Make sure the power is switched off, and the machine is completely stopped before carrying out maintenance and inspection.
Take caution so that the power does not reconnect accidentally.
Make sure the driving and driven equipment are also completely stopped.
