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 […]

What is a common coupling error in motor bracket type actuators?
Mistakes are actually quite common when selecting a coupling for a motor bracket type actuator. A small amount of planning ahead during the design phase of a motion system can make all the difference. Ruland Manufacturing VP of Sales Robert Watkins spoke with Coupling Tips.com and explained. “Another very common error that we see is […]
What are some common coupling selection pitfalls?
Coupling Tips.com spoke with Robert Watkins, VP of Sales for Ruland Manufacturing, to find out how to avoid the downtime, safety concerns, and financial risks of a poor coupling selection. Here are just a few of his best practices for making the right selection the first time. Electrical isolation. Some applications require electrical isolation. Isolation […]
Ruland: 6 common errors in coupling selection
Mistakes happen. But it sure is better to avoid them altogether, right? To show us how to prevent the downtime, safety concerns, and financial risks of a poor coupling selection, Robert Watkins, VP of Sales for Ruland Manufacturing, gave us his list of 6 pitfalls you’ll want to avoid. Here is part one of the […]
Oldham couplings for actuator driven systems
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 […]
Metric rigid couplings with step bores
Ruland has expanded its line of rigid couplings to include metric sizes with step bores. This gives equipment manufacturers designing precision servo driven systems or shaft-to-shaft connections a wider range of standard in-stock products to choose from. The couplings are available in one- and two-piece clamp styles with or without keyways for superior fit and […]
The 3 best beam coupling videos on the internet
Beam couplings are an essential motion system component for torque transmission and misalignment compensation. In this list, we’ll cover a few of the most informative, most viewed and most valuable beam style coupling videos on the internet. 1. How to Install a Beam Coupling | RULAND Great beam coupling performance starts with proper installation. Might […]
Should I choose a keyed or keyless coupling for this application?
By Joyce Laird, contributing editor Taking a look at keyed and keyless couplings from the applications point of view puts the choice in a very clear perspective. Both are needed in many applications and both bring specific features and benefits. Bobby Watkins, V.P. Sales. Ruland Manufacturing says that the first thing to look for when […]
Beam couplings for motors
Ruland beam couplings are designed to couple stepper and servo motors to encoders, lead screws, and light duty actuators in a variety of industries. They are zero-backlash, have high torsional stiffness, accommodate all forms of misalignment and have a balanced design creating a highly accurate and flexible coupling. Stepper and servo driven systems benefit from […]
The 5 best Oldham couplings videos on the web
Oldham couplings are considered a workhorse in light load, servo applications. With their electrical isolation potential, zero backlash and misalignment capabilities (okay, maybe not angular), Oldham couplings are a familiar face in motion control applications and general industrial equipment. In this list, we take a look at some of the best Oldham coupling videos on the […]
