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.
