Super elastomer coupling SURE-flex®
The SURE-flex® coupling consists of:
- two identically flanged hubs with internal and external teeth,
- a flexible sleeve also with internal and external teeth.
Standard material for the flexible sleeves is PROCOUPLAN. Unless otherwise specified, the flexible sleeve is supplied as standard in a 1-piece design (JX). An open version is also available on demand (type JXC).
Its high torsional elasticity provides the installation with a low natural frequency. Together with its capacity to dampen vibration, SURE-flex® is a very appropriate selection for applications with reciprocating equipment such as when engine driven.
The open version allows the replacement of the sleeve without moving the connected equipment. This is done by moving just the flanged hubs provided they are mounted on the shafts with a slip fit.
HYTREL® (H) material can also be supplied upon request. This type of sleeve has a torque carrying capacity which is 4 times higher but with a reduced torsional flexibility.
