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.
Location: Dallas, TX Answer:When helping the customer I realized what the problem was. Our longest Controlflex under a 2” outer diameter is 1.496” and it didn’t meet the envelope requirement. I recommended a beam coupling which would meet the envelope requirement and would fit the performance requirements of the application. This is a common issue with encoders. They are designed independent of the servo motor so each is a little bit different and that creates a wide variety in lengths. Something like a Controlflex is great for compact environments but if you need a little more length a beam coupling or an oldham coupling might be a better fit. When you use other coupling styles it does change the performance within the application, so you need to be sure that the specs of the coupling match the requirements of the application.
