Large jaw couplings are now being offered for bore sizes up to 1-3/4” or 45 mm and torque capacities of 2,655 in-lbs (300 Nm). These new large jaw couplings are designed for use in precision systems with high deceleration and acceleration curves, such as those found in semiconductor, solar, conveyor, and warehouse automation applications.
Pre-assembled modular mounting systems are designed for adjustability across many mounting applications. Conveyor mounting systems emphasize strict parallel installation using a flange-bolt base and a conveyor rail guide. Sensor mounting systems offer flexibility in a mounting application with adjustable or 90-degree connectors, two-way bases, and various mounting brackets. Both systems include stainless steel rods (with or without scale) from 100mm to 300mm in length, zinc clamping levers, and connectors that allow adjustment of the rods’ position.
Mountable shaft collars with face holes are designed to mate directly with components such as sprockets, pulleys, and metallic plates. Ruland manufactures them with drilled holes for mounting flexibility or threaded holes for the most secure connection between the collar and mated component. They are offered in steel, aluminum, and 303 stainless steel in bore sizes ranging from 3/8” to 2” and 10mm to 50mm.
Disc Couplings for Test, Measurement, and Inspection Applications
Ruland disc couplings are zero-backlash and have high torque torsional stiffness capabilities making them a good fit for many test, measurement, and inspection applications. Single style disc couplings are comprised of anodized aluminum hubs and stainless steel disc springs. They are ideal for applications with space constraints but designers must be careful when using them as they cannot support parallel misalignment. Double disc couplings are made of two anodized aluminum hubs, an anodized aluminum or electrically isolating acetal spacer, and stainless steel disc springs. The double disc style can accommodate greater amounts of all types of misalignment than single disc types, including parallel misalignment. Disc couplings have similar performance characteristics to bellows couplings with slightly less torque in exchange for better misalignment capabilities. They are well-suited for testing, measuring, and inspecting equipment that requires high torsional rigidity and speed up to 10,000 RPM, such as those found in precision vision systems. They are available in clamp and set screw hubs with or without keyways in bore sizes ranging from 1/8” to 1-1/4” and 3mm to 32mm. Ruland manufactures disc couplings in our Marlborough, MA factory under strict controls using proprietary processes.
