Flexible clamping Oldham type couplings from NBK

September 9, 2020 By Mike Santora Leave a Comment

NBK-Oldham-5919_1

This is the MOM-C, Oldham type flexible coupling from NBK. FCD400 is adopted in the spacer and the coupling is suitable for low-speed and high-torque specification. High-performance grease is applied in the gap between hubs and the spacer in order to prevent sticking. Slippage of hubs and a spacer allows large eccentricity and angular misalignment to be accepted. A […]

Stainless steel oldham couplings from Ruland

May 2, 2019 By Mike Santora Leave a Comment

Ruland-oldham-coupling-stainless-steel

Ruland now makes oldham coupling hubs from 303 stainless steel. This addition gives designers an off-the-shelf coupling to choose from when designing systems in corrosive, vacuum or cleanroom environments. Stainless steel oldham couplings are zero-backlash, can accommodate all forms of misalignment and have a balanced design, making them suitable for a wide variety of servo […]

Ruland-Logo-image

In this column, Bobby Watkins of Ruland Mfg. Co. gives us an overview of some coupling-installation best practices. Updated September 2019 ||Even if a coupling is properly selected, poor installation can cause failures. Following are four installation best practices to keep in mind when assembling your next motion design. 1. Ensure your selected coupling is […]

How does vibration and temperature affect my coupling choice?

February 15, 2019 By Mike Santora Leave a Comment

Ruland-Logo-image

Many environmental considerations affect coupling selection. There is moisture, chemicals, and vacuum, to name a few. The different types of motion-controlled couplings have a different capability in handling different environmental considerations. You want to know moisture level, any chemical presence or if you’re dealing with a vacuum and you don’t want any outgassing, that’s an important […]

What do I need to know before selecting an Oldham coupling?

May 3, 2018 By Mike Santora Leave a Comment

Ruland-Logo-image

Oldham couplings are an excellent choice when selected for the proper application. We asked Bobby Watkins of Ruland Manufacturing to give us some insight on general coupling selection. The following is an excerpt from the Oldham coupling section of his Webinar, Master Coupling Selection: A Guided Journey by Bobby Watkins. Zero backlash Oldham couplings are […]

What are couplings for power-transmission drive shafts?

May 2, 2018 By Lisa Eitel Leave a Comment

FAQ power-transmission couplings-for-high-torque-power-transmission

Updated May 2019 || As outlined in our coverage of couplings for motion control — here at this couplingtips.com article — couplings connect rotating shafts powered by a drive of some type — often an electric motor. All couplings serve to transmit drive torque and angular velocity. But applications for motion control (such as axes […]

Environmental considerations for coupling selection: fast facts

May 9, 2017 By Mike Santora Leave a Comment

ruland-bellows-coupling-installation-video-image

It takes more than just specifying size, speed rating, and torque range to assess the right coupling for an application. One of the most important factors is a coupling’s operating environment. The conditions a coupling will face can have a drastic impact on efficiency and service life. To learn more about a few environmental consideration […]

Tips for understanding torque with bellows and Oldham couplings

April 4, 2017 By Mike Santora Leave a Comment

Ruland-Oldham-disk-coupling

It’s important to note the difference between steady state and max torque based on motion type or when using a bellows vs. a disc coupling. It’s also important to understand how couplings are rated. Jaw couplings have a peak torque, for example, and rigid couplings have a superior torque capability but do not allow for […]

Oldham couplings for actuator driven systems

March 24, 2017 By Mike Santora Leave a Comment

image004

Ruland Manufacturing Co., Inc. presents Oldham couplings for actuator driven systems. The Oldham couplings are zero-backlash, have a balanced design, and high parallel misalignment capabilities, making them an ideal fit for screw driven actuator applications. The three-piece design allows designers to easily couple an actuator and motor that have keyed or keyless shafts with inch […]

Misumi Oldham couplings

January 23, 2017 By Mike Santora Leave a Comment

MiSUMi-Oldham-coupling-dimensions

Couplings are machine components designed to connect two separate rotating bodies and transmit a torque between them. They allow various misalignments (Lateral/Angular/Axial) of the rotating bodies to be absorbed, and alleviate installation and adjustment work loads. Furthermore, they protect expensive inter-connected machine components from sudden and unexpected excess loads by breaking and disconnecting. Oldham couplings, […]
