MAX-C® Resilient Couplings

Type K2

For high shock and general duty industrial applications where a maintenance-free, non-lubricated coupling is desired. The MAX-C® K2 resilient coupling has high power ratings and a large bore capacity, allowing it to be used in virtually any difficult installation. MAX-C® K2 couplings can also be used as a non-lubricated replacement for many gear couplings in heavy-duty service. For smaller sizes or less demanding service, consider a MAX-C® UB coupling.

The MC elastomer block used in the K2 coupling is specially compounded for high strength, exceeding the capability of normal rubber block couplings. This combination of strength and resilience allows the K2 coupling to be successfully applied to equipment with torque reversals, high momentary torques, start and stop operation and impact and shock loading.

Typical applications include runout tables, conveyors, overhead cranes, fan drives, and any service where shock loading is present. K2 couplings are not meant to be used for reciprocating equipment, synchronous motor or variable frequency motor drives, or where a large amount of torsional displacement is required. For these applications an engineered MAX-C^® CB or WB Type coupling should be considered.
