Ruland Manufacturing has released mountable shaft collars with face holes for applications where the collar needs to be directly fastened to a component such as a pulley, sprocket, or metallic plate. Shaft collars are used to properly position components, holding them securely in place.
The shaft collars are available with drilled face holes that give users flexibility in mounting hardware or tapped holes that match the standard screw threading of the collar for ease of installation.
Ruland designs and manufactures face-mount shaft collars for an ideal fit, finish, and holding power. They have precise face-to-bore perpendicularity (TIR ≤ 0.002 inch or 0.05 mm), which is critical for mounting to applications. The groove in the face of the collar identifies the work surface for easy installation.
The new face-mount shaft collars have a burr-free finish, making them an ideal solution for applications in industries such as medical, food, and semiconductors, where contamination is unacceptable. The shaft collars undergo proprietary manufacturing processes to maintain their round bore geometry for tight tolerances, proper installation fit, and improved clamping capabilities.
The mountable shaft collars with drilled holes allow for a wider variety of inch or metric mounting hardware to be used. Tapped holes provide a direct interface between the collar, screw, and mated component for the most reliable fit. Either configuration can accommodate socket head, set, or button head screws. The face holes are aligned 180 degrees from each other, allowing the user to install the collar in any orientation.
The materials available are 1215 lead-free steel for high strength, 2024 aluminum with an anodized finish for lightweight, and 303 stainless steel for corrosion resistance. They’re available in one-piece clamp style in bore sizes from 3/8 to 3 inches and 10 to 80 mm.
