Chloroprene rubber compounds are available for use in adverse operating conditions (e.g. oil or grease contamination) and can be used in temperatures of –15 O C to +70 O C. The chloroprene compound should also be used when fire-resistance and anti-static (FRAS) properties are required, and it is this tyre material that is used with specific flange modifications in the ATEX approved variant. SELECTION (a) Service Factor Determine the required Service Factor from table below. (b) Design Power Multiply the normal running power by the service factor. This gives the design power which is used as a basis for selecting the coupling. (c) Coupling Size Refer to Power Ratings table (page 114) and from the appropriate speed read across until a power greater than that required in step (b) is found.The size of Fenaflex coupling required is given at the head of that column. (d) Bore Size Check from Dimensions table (page 115) that chosen flanges can accommodate required bores. EXAMPLE A Fenaflex coupling is required to transmit 45kW from an A.C. electric motor which runs at 1440 rev/min to a rotary screen for 12 hours per day. The motor shaft is 60mm diameter and the screen shaft is 55mm diameter. Taper Lock is required. (a) Service Factor  The appropriate service factor is 1.4. (b) Design Power  Design power = 45 x 1.4 = 63kW. Type of Driving UnitSPECIAL CASES For applications where substantial shock, vibration and torque fluctuations occur, and for reciprocating machines (e.g. internal combustion engines, piston pumps and compressors) refer to your local Authorised Distributor with full machine details for analysis.

(c) Coupling Size By reading across from 1440 rev/min in the power ratings table the first power figure to exceed the required 63kW in step (b) is 75,4kW. The size of coupling is F90 Fenaflex. (d) Bore Size By referring to the dimensions table it can be seen that both shaft diameters fall within the bore range available.

A chloroprene compound is available which is Fire Resistant and Anti-Static (FRAS) and has greater resistance to heat and oil.This is suitable for operation in temperatures –15 O C to +70 O C. For temperatures outside these ranges – consult your local Authorised Distributor.The FRAS tyre variant is used with specifically modified metal flanges to create the ATEX approved variant.
