Description

R&D Marine has developed a comprehensive range of Split Shaft Couplings for Volvo transmissions with flange sizes from 4” to 5” diameter. Split Shaft Couplings can accommodate the variations that occur with normal shaft tolerances, are easy to install, and can be adjusted to the required position on the shaft.

Features

Easy Installation & Removal

By clamping onto the shaft the R&D Marine Split Shaft Coupling can overcome normal shaft tolerances. Easy to remove shaft, even after years of use. Provides a better fit and face than a solid slip-on coupling.

Increased Strength

Unlike other shaft couplings on the market that are cast steel, the R&D Marine Split Shaft Couplings are machined from solid steel. This gives increased strength and durability.

Split shaft coupling

Everything worked as planned. Easy installation with no problems

Good service

Hi, we bought items for my propulsion.
Professional, rapid and good help all the way. I'll buy again when need arises.. Keep up the good work

EXCELLENT SERVICE, TIMING AND PRODUCT

Fred Hutchison Helped me thru the chat right away, and it was immediately clear that he knew his product and field thru experience. They custom bored my shaft coupler and had it shipped with the flexible coupler within 2 days. Any questions I have had since, Fred or his team have responded right away. Pleasure to work with !!

Great Customer Service

There is always some there to answer the phone without waiting forever. The staff is always friendly and knowledgeable. A true example of excellence.

High Quality

PYI employ excellent machinists using the best materials for their products. I use their drip less-shaft seal, a split-coupling and a flexible coupling.
