Coupling claims true "fit-and-forget"
solution
The latest short DBSE coupling design from John Crane brings important new benefits to any application where existing gear-type and grid couplings have traditionally been used.
The latest short DBSE (distance between shaft ends) coupling design from John Crane brings important new benefits to any application where existing gear-type and grid couplings have traditionally been used Developed in response to specific customer requests, the new TSR coupling needs no lubrication, no maintenance, and provides a true "fit-and-forget" solution with a virtually infinite operating life

Sealing system eliminates O-rings
Latest development to the John Crane GD Gas and Dry Lubricated vessel and reactor sealing system is the elimination of O-rings through a spring-energised PRP ring for secondary and shaft sealing
In contrast to existing gear couplings - which frequently suffer from poor lubrication, seizures that cause broken shafts, and excessive tooth wear due to flexing - the ATEX approved TSR is a dry membrane coupling specifically designed for applications where the DBSE is between 3 and 50mm.
It has no relative moving parts that might wear, and so needs no lubrication or maintenance.
The TSR will flex to accommodate lateral movements, making it ideal for short DBSE motor to gearbox connections where a high degree of reliability is required.
A split spacer design allows easy access to the TSR membrane elements for maintenance or replacement without removing either of the connected pieces of equipment.
This makes the TSR ideal for any application where space or access is restricted.
The split spacer also permits easy mechanical isolation, and simplifies both shaft alignment and checking the directional rotation of the motor.
Complementary couplings for both standard and long DBSE applications are also available from John Crane.
Designed to be easily retrofitted by the end user, the standard TSR design also offers a number of versatile installation options which allow it to accommodate a wide variety of application lengths.
This means that customers need hold only minimal spares stock.
As with all John Crane products, the TSR is easily available from any location, and is supported by a genuinely global service and customer support capability.
