CF-A O0/O1/O2 Types - CENTAFLEX - MIKI PULLEY COUPLINGS - MIKI PULLEY VIETNAM

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.

*Max. rotation speed does not take into account dynamic balance.

*The dynamic torsional stiffness is about 1.3 times that of the static torsional stiffness.

*Values for moment of inertia and mass are those when the cylindrical hub and flange hub have pilot bores.

*Pilot bores are to be drilled into the part. Minimum values for d1 and d2 are given by the minimum bore diameter values in the MIKI PULLEY standard hole-drilling standards and maximum values from the maximum allowable drilled bore diameters.

*The above table values are dimensions when the rubber body is assembled, so the N1, TK, D1, and D2 dimensions prior to rubber body assembly will differ from those above.

*The TK dimension is the bolt mounting pitch diameter of the flange hub or paired mounting part.

*The nominal diameters for bolts M1/M2 are equal to the quantity minus the nominal diameter of the screw threads.

*Using a hex-socket-head bolt with the CF-A-400 requires a special flat washer.

*CF-A-O2 data is used as the CAD data.
