CENTAFLEX

Highly flexible elastic couplings

Rubber couplings dampen and absorb shock and vibrations using the elasticity of rubber, while plastic couplings do the same with plastics. Their advantages include high flexibility, low noise, easy maintenance (because they do not require lubrication), simple construction, and long service life. They have been widely used in engines for construction machinery, ships, generators and the like, as well as in ordinary industrial machinery.

CF-A Models

Power is transmitted by highly elastic rubber.Rubber is excellent at absorbing vibration and shock and also reduces machinery noise. The rubber components of the elastic body are constructed of polygonal rubber with aluminum inserts inserted into their tips. Each is formed by rigid vulcanizing adhesion. These rubber bodies are coupled by bolts in the radial and axial directions of the cylindrical hub and flange hub so that power is transmitted via the rubber body. The bolt coupling in the radial direction is particular has a pre-compressed construction and enables power transmission that is excellent in flexibility and absorption of vibration and shock.

CF-H Models

Motive power is transmitted by polyester resin that has the elastic force of rubber.These models boast excellent vibration and shock absorption while achieving resistance to heat, cold and oil not shown by natural rubber. They can also easily engage or isolate input/output simply by moving in the axial direction, facilitating maintenance.

CF-X Models

These models use high-quality nylon resin for the buffer material. This construction and element material mean they are rigid in the torsion direction, have excellent flexibility in the bending and axial direction, and have no backlash. They absorb vibration and shock while delivering accurate power transmission. These models have a simple construction comprised of element (buffer material), cylinder hub, flange hub, and a bolt for locking the element in place.

CF-B Models

Since a highly elastic resin (polyurethane/polyester) is used as the buffer material of the element, vibration and shock absorption during power transmission is excellent and noise is also reduced.The construction is a compact and simple design that sandwiches the element between two hubs, so mounting and removal is easy, facilitating maintenance of the device as a whole.

CM Models

These are couplings for engines that transmit power using highly elastic rubber and are excellent at absorbing vibration and shock. They are very soft in the bending direction, and are able to escape the resonance point caused by torsional vibration at or below engine low idle.Being short in the axial direction, they do not require space and can easily engage or isolate input/output simply by moving in the axial direction, facilitating maintenance.
