Roller chain coupling stainless steel series (wrap type coupling)

Austenitic stainless steel is used for the roller chain and sprockets.
It can also be used in harsh environments that were difficult for conventional steel Roller chain coupling to handle.
・Applicable shaft diameter: Φ11mm to Φ140mm
Torque range: 74 to 5883 Nm

Features

・Excellent corrosion resistance

Suitable for use outdoors or in corrosive atmospheres such as acidic or alkaline.

[Major applications]: Water gates, food machinery (brewing, fermented foods), rigging equipment, etc.
・Operating temperature range

Without case: -20 to 200°C / With case: -10 to 80°C

*Please contact us if you plan to use the product with a case at temperatures exceeding 80°C.

Chemical resistance varies considerably depending on the conditions of use, so it is not a guarantee.

Please refer to the table above and confirm chemical resistance under actual usage conditions before deciding on specifications.

-The main body consists of an austenitic stainless steel sprocket and a dedicated two-row roller chain (stainless steel).

- Stainless steel joint links and spring clip are also included as special parts.

Be sure to use the case in the following cases:

- A dedicated case for the Roller chain coupling series.
- By attaching it to a chain coupling, it prevents lubricant from scattering and dust from entering, extending the life of the coupling.
- It has a split shape that can be separated perpendicular to the axis, making it convenient for installation and inspection.

-The case is made of die-cast aluminum and has a two-part structure, with gaskets (cork with synthetic rubber) attached to the mating surfaces.
- Parts include four hex socket bolts and a dedicated oil seal (NBR).
・Oil seals and packings are sold as individual parts. Lubricating grease must be purchased separately.

- Install the oil seal on the side with the greatest vibration.
- When using vertically, the oil seal side should be on the top side.
If you would like to take measures to prevent grease leakage, a quote will be required, so please contact us.
-Painting specifications: Melamine resin baked paint
