LARGE BORE ZERO-BACKLASH JAW COUPLINGS
Ruland’s new zero-backlash jaw coupling line includes sizes up to 45 mm with increased torque capabilities
The expansion of Ruland’s jaw coupling
range means designers can now use them in a wider range of applications
are now available up to 45mm and torque capacities of 300 Nm. These new jaw couplings are designed for use
R
in precision systems with high deceleration and acceleration curves, such as those found in semiconductor, solar, conveyor and warehouse automation applications.
uland Manufacturing has expanded its jaw coupling line to meet the demands of high-torque applications. Bore sizes
advanced polyurethane material, the spider damps impulse loads, minimising shock to the motor and other sensitive equipment.
FOR A BROAD RANGE OF APPLICATIONS “The expansion of our jaw coupling line allows designers to implement Ruland products in a broader range of applications, giving them the flexibility to handle higher torque requirements
“The expansion of our jaw coupling line allows designers to implement Ruland products in a
broader range of applications, giving them the flexibility to handle higher torque requirements with the reliability they expect from Ruland”
With zero-backlash, industry-leading misalignment capabilities, and a balanced design that reduces vibration at speeds up to 8,000 rpm, Ruland jaw couplings deliver optimal performance for demanding environments. Ruland jaw couplings offer the highest size-
for-size torque and torsional stiffness of the company’s flexible couplings product line. They consist of two precision-machined aluminium hubs connected by an elastomeric element called the spider. The curved jaw profile of the hubs presses fits with the spider, ensuring zero-backlash performance. Made from
with the reliability they expect from Ruland,” says Bill Hewitson, president of Ruland Manufacturing. “These jaw couplings underwent rigorous physical testing to guarantee zero-backlash operation and adhere to the stated misalignment ratings, setting us apart from competitors. I am excited to support our OEM and distribution customers with these new products.” Ruland manufactures zero-backlash jaw
coupling hubs from meticulously selected, high- strength, 2024 aluminim North American bar stock for lightweight, low inertia performance. Designers can mix and match hub and spider
Advantages at a glance:
• High torque coupling with up to 300Nm of torque
• Bore sizes now available up to 45mm • Reduced vibration at speeds up to 8,000 rpm because of a balanced design
• Ratings validated through thorough physical testing • RoHS3, REACH, and Conflict Minerals compliant
combinations to tailor coupling characteristics to their specific system needs. Clamp style hubs are available with or without keyways, in bore sizes ranging from 3mm to 45mm. Spiders are available in 98 Shore A hardness for maximum torque and torsional stiffness capabilities and 92 Shore A hardness for enhanced damping and misalignment capabilities.
MANUFACTURING Ruland manufactures jaw couplings in its ISO 9001:2015 certified advanced manufacturing facility in Marlborough, Massachusetts, USA, under strict quality controls using proprietary processes. The couplings are RoHS3, REACH, and Conflict Minerals compliant. Full product specifications, CAD models, and instructions can be found at
