The Acme Threaded Collar from Ruland is a precision-engineered component designed for applications requiring high axial holding power and precise alignment. Its trapezoidal threading and double-tapped bore ensure a burr-free finish, extending shaft life and facilitating easy installation. With its tightly controlled face-to-bore perpendicularity (TIR of < 0.05mm), this collar is ideal for load-bearing faces, mechanical stops, and component alignment. Manufactured from 303 stainless steel, it offers consistent corrosion resistance and meets or exceeds DIN 912 12.9 standards for holding power. Suitable for use in various industries, including aerospace, medical, and industrial automation, this collar provides reliable performance and long-lasting durability.
Top product features:
Infinitely adjustable to accommodate various shaft sizes
Has superior holding power compared to set screw collars
Maintains tightly controlled face to bore perpendicularity (TIR of < 0.05mm) for critical applications
Ruland clamp style shaft collars do not mar the shaft, are infinitely adjustable, and have superior holding power when compared to set screw collars. This one-piece trapezoidal threaded shaft collar has an M16 x 3 bore, 34mm OD, and 13mm width. Threads are double tapped to ensure a burr-free finish which extends shaft life and allows for easier installation. Trapezoidal threading allows for higher axial holding power than traditional threaded collars. Tightly controlled face to bore perpendicularity is maintained (TIR of < 0.05mm) which is critical when the collar is used as a load bearing face, mechanical stop, or for component alignment. The work surface is identified by two grooves on the face allowing the user to easily identify which side is precision faced. This collar is stamped with the Ruland name and bore size for ease of identification. It is manufactured from 303 stainless steel to a fine burr-free finish with hardware of like material for consistant corrosion resistance. Hardware tests beyond DIN 912 12.9 standards for maximum holding power. It is RoHS and REACH compliant.
