Malfunctions happen. And when they do, damage and repair costs follow. Safety couplings are the mechanical connecting elements designed to protect other machine components surrounding a drive system. When a malfunction occurs, safety couplings help keep the damage to a minimum. Safety couplings include torque limiters to handle mechanical overload. In disconnect types, torque limiters […]

Miki Pulley introduces its Jaw Type shaft coupling to the U.S. market
Miki Pulley is introducing its Jaw Type, High RPM coupling for direct sale to OEM’s in North America. This ALS-SGN model handles speeds to 22,000 RPM. Designed for use in the main spindle shaft on CNC machining centers, the Miki Pulley ALS-SGN coupling uses unique taper-lock hubs. This hub design ensures concentricity and rotational balance […]
Jaw coupling overview – features, benefits & design basics
Jaw couplings are a general, all-purpose industrial power transmission device that operates in a range of temperatures, handles angular misalignment and the accompanying reactionary loads, resists chemicals and has good speed and dampening capabilities. A basic jaw coupling is made of three parts: two hubs, generally bored to a clearance fit tolerance, and an elastomeric […]
Pick the right coupling for each high tech application
Selecting the right coupling for your application is critical to system safety and reliability, says Ruland Manufacturing Co. Inc., Marlborough, Mass., which manufactures a diverse couplings product line while providing technical support and application experience. Ruland’s coupling line includes rigid couplings with precision honed bores and five types of zero-backlash couplings: beam, bellows, disc, jaw, […]
Lovejoy and VibrAlign develop partnership, educational series
Lovejoy Inc., Downers Grove, Ill. and VibrAlign Inc., Richmond, Va., have developed a strategic alliance to create improved educational opportunities for users of couplings and shaft alignment tools. In addition, the two companies are partnering to bring a traveling educational series to several locations in the next two months. Founded in 1900, Lovejoy specializes in […]
Robust jaw couplings make for easy water testing
Testing water samples is an important and critical business, so when Hach Co., Loveland, Colo.—a provider of water quality testing and water quality analysis—was designing one of its signature samplers, it wanted a design that was maintenance free and wouldn’t cause any problems. That’s why Hach turned to R+W America, as it worked on the […]
Zero Backlash Jaw Couplings from Ruland
Ruland offers zero backlash jaw couplings for the demanding requirements of start and stop machine vision systems used in industries such as semiconductor, medical, solar, and packaging. The dampening characteristics of Ruland’s jaw couplings reduce settling time and shock loads, making them ideal for these environments. Jaw couplings are a three piece design comprised of […]
A Novel Way To Use Jaw Couplings In Extreme Temperatures
The German couplings specialist, KTR, has come up with a novel way to use jaw couplings in temperatures too high for the elastomer materials conventionally used for coupling spiders. It has developed a spider made from “knitted” steel wire, similar to the steel wool used to clean pots and pans. Standard spiders are made from […]
New Jaw Couplings Have Zero Backlash
Zero backlash jaw couplings that are three piece couplings comprised of two hubs and a plastic element are one of Ruland Manufacturing’s new products in their coupling line. The Spider, shown below, made of an advanced polyurethane material, provides dampening of impulse loads, minimizing shock to the motor and other sensitive equipment. Available in two […]
Miniature Rigid Couplings Bore Size Down to 3mm
Ruland now offers miniature rigid couplings with bore sizes as small as 3 mm. Miniature rigid couplings are suitable for micro component applications where misalignment is neither present nor desired, including connecting line-shafts, attaching a motor to a gearbox, and servo applications. Offering high torque capacity, stiffness and zero backlash, Ruland’s rigid couplings are increasingly […]
