The Samiflex elastic insert is manufactured from a special blend of polyurethane compound manufactured to best meet the demanding characteristics of a high performance elastic coupling.
Samiflex elastic inserts are offered in three styles of compound and four hardness ratings allowing the most appropriate insert to be selected for the application.
The standard elastic insert is supplied at 95 shore and is a yellow colour. High performance inserts type HD and HDT are coloured ochre and red respectively and enable Samiflex torque ratings to be increased by 40% (consult factory).
