E-Catalog > 1 Miki Pulley Flexible Coupling > Centa Flex Coupling

Motive power is transmitted though a high elastic rubber. It is excellent in absorbing vibrations and shocks. Noise of machinery is also reduced. The rubber part is composed of a polygon rubber and aluminum insert inserted at the top, and each part is tightly attached by vulcanizing. Power transmission is accomplished by fixing the rubber body in the hub and flange hub in a radial direction and axial direction respectively by bolts. Especially for a radial directional coupling, a precompressed construction of deformed rubber body enables a power transmission excellent in flexibility and absorbing vibrations and shocks. Rubber parts are available in two types, bolt mounted type (O0) and bayonet mounted type (S0).

Torque transmission	10Nm to 5000Nm
Torque transmission	10Nm to 5000Nm
Operational temperature	-30oC to +95oC

Motive power is transmitted through a polyester resin (Hytrel) that has elasticity like that of rubber. It is excellent in absorbing vibrations and shocks. It also excels in resistance to heat, low temperature and oil. Input and output can be connected and disconnected easily merely by moving axially. By using a unique claming mechanism (CENTA-LOCK), mounting in a spline shaft is possible. Hub and spline shafts are completely fixed by using a clamping hub of the CENTA-LOCK mechanism. No fretting wear is caused. (Clamping hub of the CENTA-LOC mechanism is available by special order.)

Torque transmission	100Nm to 2500Nm
Torsional amount during rated torque	0.2deg. to 0.3deg.
Operational temperature	-40oC to +120oC

High-quality special plastic material (Zeitel) is used for the cushioning material. It is hard in a torsional direction and has excellent flexibility in bending and axial directions. The O2 type consisting of an element (cushioning material), cylindrical hub, flange hub and fixing bolts and OG type with two elements connected by a floating shaft are available. The OG type can be detached without moving the drive by removing axial bolts.

Torque transmission	15Nm to 370Nm
Torsional amount during rated torque	0.12deg.
Operational temperature	-30oC to +90oC

Elasticity-rich plastic (polyurethane or polyester) is used for the cushioning material as an element. It is excellent in absorbing vibrations and shocks during power transmission. Noise is also reduced. The CF-B-H type with polyester resin excels in resistance to heat and low temperature and has over twice the torsional rigidity of polyurethane resin. Due to the compact and simple design with an element between two hubs, mounting and dismounting are easy. Maintenance is easy as well.

Torque transmission	30Nm to 1400Nm
Torsional amount during rated torque	2.5deg./CF-B,4deg./CF-B-H
Operational temperature	-40oC to +80oC/CF-B,-40oC to +80oC/CF-B-H

The CENTAMAX is a coupling for engines. The elasticity-rich rubber transmits power and well absorbs vibrations and shocks. It is flexible in a torsional direction and downs a resonance point caused by torsional vibration to below engine low idling. It is short in an axial direction to save a space. It can be directly mounted in engine fly wheels compatible with SAE standard J620. Input and output can be connected and disconnected easily merely by moving axially. Maintenance is easy as well.

Torque transmission	120Nm to 14000Nm
Torsional amount during rated torque	12deg.
Operational temperature	-30oC to +80oC
