Roller chain coupling (Wrapped type coupling )
- Constructed of two-strand chains and two sprockets.
- Can be connected and separated without moving the equipment by winding the chains over and removing them from the sprockets.
- ・Applicable shaft diameter :Φ9.5mm~Φ700mm
- ・Torque range :99.9~717000N・m
Features
-
・Excellent Durability
The coupling provides outstanding durability with the torque distributed to the strong roller chains and surface-hardened sprocket teeth.
-
・Easy Coupling and Decoupling
Can be connected and disconnected by simply inserting and extracting a single roller chain joint pin.
-
・Absorption of Large Misalignment
The clearance between the components absorbs large misalignment of both shafts.
-
・Wide variety of products available.
A total of 24 models, including 15 models compliant with JIS standards and 9 other models, are standardized. (Roller chain coupling JIS B 1456-1989)

※Max. allowable transmission torque at below 50 r/min.
Construction
- ・The body consists of two special sprockets with hardened teeth and dedicated two-strand roller chains.
- ・A joint pin and a clip/split pin are attached.
※These components are also sold separately.
Housing (Selling seperately )
Please mount a casing in the following cases,
- (1) Used at high rotating speeds.
- (2) Used under abrasive conditions, such as dusty areas.
- (3) Used in corrosive environments, such as moist areas.
- ・When mounting the casing, the chain coupling life is extended due to the prevention of lubricant splash and dust infiltration.
- ・For ease of mounting and inspection, the casing can be split at a right angle to the shaft.
Casing Structure
- ・The casing is made by aluminum die-casting or aluminum casting, and has a structure that can be divided into two parts. A packing made of rubber cork is attached to the mating face.
- ・Parts include 4 to 6 hex socket head bolts and a special oil seal.
- ・The oil seal and packing are also sold separately. Please purchase lubricating grease.

- ・Install the oil seal on the side subject to greater vibration.
- ・When used vertically, the oil seal side should be the top side.
If grease leakage countermeasures are to be taken, please contact us for a quotation.
