Large Specialty Couplings

These couplings have a different shape and application from the standard types. The lineup includes special models from various manufacturers such as Miki Pulley, Sakai Manufacturing, Nitta Chemical Industrial Products and Mighty Corporation. Coupling types include those coated with strong rubber designed to cushion impacts; large types with different shaft centers that use crank motion; and types that use high-quality nylon resin as cushioning material. A wide range of coupling shapes and structures are available for different applications.
