Mountable Shaft Collars: Flats & Mounting Holes
Mountable shaft collars with outer diameter (OD) flats and holes are used for mounting sensor brackets, mounting collars to each other, and welding items such as plates or hinges to the collar. They are comst commonly used in applications such as cylinders where the collar can be mounted to a base plate. Along with mounting they can be used as a traditional shaft collar for guiding, spacing, stopping, and component alignment. They have tightly controlled face to bore perpendicularity (TIR ≤ .002" or 0.05mm) which is critical when the shaft collar is used as a load-bearing face, mechanical stop, or for aligning components on a shaft. The tapped holes in the OD fit standard cap, torx, or set screws allowing the designer to use hardware of their choosing to match application requirements. Mountable shaft collars with OD holes are available in 1215 lead-free steel for the greatest holding power, 2024 high-strength aluminum for light weight, and 303 stainless steel for corrosion resistance. Ruland manufactures them in one- and two-piece clamp styles with bore sizes range from 3/8” to 2” and 10mm to 40mm.
