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 Semiconductor & Solar Applications
Semiconductor and solar equipment such as wafer handlers, screen printers, and bonders often require rapid, short, precise movements to precisely position wafers, panels, or chips. The high torsional stiffness and torque capabilities of Ruland disc couplings make them an excellent choice for these highly accurate systems in applications with speeds up to 10,000 RPM. Disc couplings have similar performance to bellows couplings with slightly less torque capacity in exchange for greater misalignment capabilities. Ruland manufactures single and double disc couplings to meet the needs of semiconductor and solar applications. Single disc couplings are comprised of two lightweight anodized aluminum hubs joined by stainless steel disc springs. They are ideal for space constrained applications but cannot accommodate parallel misalignment. Double disc couplings are made from two lightweight anodized aluminum hubs, an anodized aluminum or electrically-isolating acetal spacer disk, and stainless steel disc springs. This design allows for equivalent torque and torsional stiffness as the single type with the ability to accommodate all forms of misalignment. Ruland disc couplings have a balanced design for reduced vibration at speeds up to 10,000 RPM. They are available with clamp or set screw hubs. Bores can be keyed or unkeyed and are available in sizes from 1/8” to 1-1/4” and 3mm to 32mm with or without keyways.
