Hex keys (or allen wrenches) are used to tighten or loosen fastening hardware. They can be used with Ruland shaft collars and couplings as well as with other standard industrial applications. Ruland hex keys are made of high torque protanium steel that is up to 20% stronger, with more torque and twice the wear resistance of standard grades of steel. Ball End inserts into a screw at a 25° angle, allowing natural hand and wrist movement. Chamfered tips with no burrs or imperfections allow the tool to fit properly and seat fully within the screw head. Custom heat-treating produces tools that are highly resistant to breakage and shattering. Sets come in a plastic carrying case with large labels for organization and quick selection.

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.

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.

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.
