L coupling contain only three jaws andone spider insert. Power is transmitted between the jawhalves by the insert, which is offered in a choice of fourmaterials to suit all the application characteristics andhorsepower requirements.

2 All sizes are dimensionallyinterchangeable with industry standards, making replacementin existing installations easy and L Jaw Couplings are designed for light to medium dutyapplications up to 112 Kw at 1500 rpm, and are available forshaft sizes from 1/8 ( ) to 60mm. L Series Couplings offer a choice of 4 insert typesfor maximum SelectionMorse Type L Jaw Couplings are designed for applicationsin the light-to-medium duty range, with capacities andperformance characteristics depending on the type of insertused. For maximum versatility in selection, Morse offers fourdifferent insert materials to suit the is the standard flexible insert material in Type L JawCouplings, serving the majority of applications.

3 Thematerials is an oil resistant rubber compound with excellentflexibility and shock absorption; temperature range is 40 Cto +100 urethane insert offers approximately 50% greater torquecapacity, than standard Buna-N, and in addition providesgood chemical resistance. Temperature is 35 C to 70 This tough flexible plastic material provides still greatertorque capacity, approximately three times that of standardBuna-N, and superior temperature resistance with a rangeof 50 C to +120 C. Oil and chemical resistance (Only used in L Series )This insert is intended exclusively for high torque, lowspeed applications, up to 250 rpm only.

4 Capacities are threetimes those of standard Buna-N. The material offersexcellent resistance to oils, chemicals and extremetemperatures 40 C to +230 Characteristics of InsertsMaterialFlexibilityShockOilChemic alTemperatureAngularParallelAbsorptionRe sistanceResistanceRange ( C)MisalignmentMisalignmentMisalignment Capability - Simplified Installation and MaintenanceSince power is transmitted between the two halves of the Type L Jaw coupling by the resilient insert, it is not necessary to haveperfect alignment between shafts. The elastomeric design permits angular misalignments up to 1 (1/2 for Hytrel and Bronze) andparallel misalignment up to , greatly simplifying installation in all types of industrial applications.

5 Maintenance is minimal; the insert can be visually inspected, never needs lubrication, and in fact, the coupling can continue to transmit power even if theelastomeric insert becomes severely damaged or destroyed - minimising downtime and increasing e l : + 4 4 1 2 1 3 6 0 0 1 5 5 F a x : + 4 4 1 2 1 3 2 5 1 0 7 9 E m a i l : s a l e s @ c r o s s m o r s e . c o m INDEX BACKNEXT T e l : + 4 4 1 2 1 3 6 0 0 1 5 5 F a x : + 4 4 1 2 1 3 2 5 1 0 7 9 E m a i l : s a l e s @ c r o s s m o r s e . c o Part.
