    Balance Condition
This coupling is designed with a high inherent balance, due to the precision of the manufacturing process. It is important
that all parts are carefully stored and fitted to maintain this integrity.
The inherent balance of the TSR/TLR range meets AGMA standard 9000-C90 class 8. The maximum operating speeds
listed in the table on page 2 are on the basis of this AGMA class 8 characteristic, to provide a general guide to maximum
permissible speed. If higher speeds are required contact John Crane for an alternative coupling selection or special balance
if required.
