TINYMITE™ Oldham Shaft Couplings

Basic design

Inherent in the Oldham design is a unique characteristic-uniform velocity, regard­less of shaft misalignment. In their original form, Oldham type couplings had backlash, needed lubrication, and accepted little angular misalignment. Renbrandt is the originator of improvements which greatly enhance their performance.

The Nylon centerpiece virtually eliminates backlash, noise, and the need for lubrication. The cylindrical cross pins permit greater angular misalignment (up to 5º).
