Rino Industries has launched a new range of rubber, jaw-type shaft couplings that are said to combine the zero-backlash advantages of metal with the general advantages of rubber couplings.
For this reason, the new MJT couplings are suitable for use in applications requiring rotation-angle transmission without backlash, or in applications necessitating torque transmission.
The couplings have a unique design with a polyurethane sleeve, pressed and assembled between two aluminium hubs.
There are three sleeve types available, black, white and red, which vary in hardness depending on the properties required for each application.
Selecting a harder sleeve eliminates backlash, but, unlike metal couplings, the MJT design will also absorb torsional vibration.
The new couplings are also able to deal with higher torque values than metal couplings and are therefore suitable for applications such as pumps and general production machinery where zero backlash is necessary.
The new range is available with six outer diameters from 14 - 65mm and features four standard types of shaft attachment.
Easy-to-attach setscrew and clamping types for low torque, zero backlash applications, or clamping-key types for high torque applications.
