BELLOW FLEX Coupling (Plastic bellows coupling)
Vibration is absorbed by a plastic boot rich in elasticity. Shaft reaction force due to mounting misalignment is extremely small. It has a compact and lightweight design integrating an aluminum alloy hub and boot. Due to the integral construction, it is easy to mount and dismount. Also, backlash is not caused.
Three sizes with maximum parallel offset 0.5mm and maximum angular misalignment 10 deg. are available.

- CHP Models
These couplings absorb vibration and have extremely low counter force caused by mounting misalignment, thanks to the use of a plastic boot made of resin with excellent elastic properties (polyester resins). They are compact and lightweight, since the aluminum alloy hub and boot are designed with a unitized construction. Thanks to the unitized construction, they are easy to mount and remove, and there is no backlash. They come in three sizes, and all are highly flexible couplings that allow eccentricity of 0.5 mm and an angle of deflection of 10°.

Features of CHP Models
These couplings absorb vibration and have extremely low reaction force from mounting misalignment, thanks to the use of a plastic boot made of resin with excellent elastic properties (polyester resins). They are compact and lightweight, since the aluminum alloy hub and boot are designed with a unitized construction.Thanks to the unitized construction, they are easy to mount and remove, and there is no backlash.
Allows angle of deflection of up to 10°
Boots made of polyester resin exhibit excellent flexibility.
Small shaft reaction force due to mounting error
By using boots made of polyester resin, vibration can be absorbed and shaft reaction force due to mounting errors can be kept extremely low.
