Rigid piping willresult in excessive loads on the ro -torseal bearings, shortening life.Maximum applied air pressure is 110psig (7.5 bar). Operation at pressuresexceeding 110 psig may result indamage to the element. Consult thefactory if operation at pressuresgreater than 110 psig is desired.3.0 OPERATIONExceeding the operating limitsdescribed in this section may resultin personal injury or equipment dam -age.3.1 Torque, RPM and Pressure Limits3.1.1 The developed torque is dependent upon theapplied air pressure and operating speed. Ifthe developed torque seems inadequate,check for oil, grease or dust contamination.Maximum applied air pressure is 110psig (7.5 bar). Operation at pressuresexceeding 110 psig may result indamage to the element. Consult thefactory if operation at pressuresgreater than 110 psig is required.The non-asbestos friction materialused in Airflex CB units may not de -velop rated torque initially. A short“wear in” period is required. Clutchor brake operation should be moni -tored closely to prevent excessiveheat generation from slippage.3.1.2 Maximum safe operating speeds are shownin Table 3.Do not exceed the operating speedsshown in Table 3. Operation atspeeds greater than allowable will re -sult in permanent damage to the ele -ment, personal injury or death.PDF Format 8 © Copyright Eaton Corp., 2001.
