Large Size Couplings with Special Structure（Allowable Lateral Misalignment Range：0.41 ~ 1.0）

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.

Center Flex CF-B

MIKI PULLEY

Large special coupling that dampens and absorbs shocks and vibrations.
[Features]
· A type that uses resin (polyurethane, polyester) for the element . Long lifespan.
· Has an excellent vibration and shock absorption as motion is transmitted by a highly elastic element. Reduced noise.
· The polyester resin has excellent heat-resistance, cold-resistance and at least twice the torsional rigidity of polyurethane resin.
· Requires almost no maintenance. Motion is transmitted smoothly even if there is a misalignment between the 2 shafts.
· Easy to install and remove due to a compact and simple design with only a cushioning material inserted between the 2 hubs.
· Maintenance of the entire equipment is easy.
[Applications]
· Ideal for electric motors and pumps as well as the general industrial machines.

Rubber-Flex Coupling RF Type

TOYO TIRE & RUBBER

The RF type is a coupling that has a reinforced fiber core body and both faces have been coated in rubber to make it exceptionally strong against bending fatigue.
[Features]
· Extremely flexible.
· Excellent in shock absorption and torsion damper performance.
· The structure is simple and easy to attach and remove.
· Lubrication-free, easy maintenance and economical.

Center flex CF-A

MIKI PULLEY

A type of coupling that can absorb and alleviate shock and vibrations. A type that uses natural rubber for the element.

[Features]
· Transmits power using rubber with excellent elasticity, and has excellent vibration and shock absorption.
· Reduces the noise from machinery and devices.
· Short in the axial direction to save space.
· Uses a heat-resistant rubber, and achieves a long life by using a rubber pre-compressed structure.
· Requires almost no maintenance.
· There are two types of rubber bodies. One type that is a bolt mount type (O0) in the axial direction and one type that is an insert mount type (S0) in the axial direction, and both of these are easy to align.
· The bolt can be removed to completely separate the power.
