The Ruland Acme Threaded Collar is a precision-engineered component designed for use in applications requiring high axial holding power and precise alignment. Its two-piece design allows for in-place installation and servicing, reducing downtime and increasing efficiency. Manufactured from 303 stainless steel, this collar offers superior corrosion resistance and a fine burr-free finish. Suitable for use as a load-bearing face, mechanical stop, or component alignment, the Acme Threaded Collar is ideal for applications in industries such as aerospace, medical, and precision machinery. Its high-quality construction and precise tolerances ensure reliable performance and extended shaft life.
Top product features:
This two-piece acme threaded shaft collar has a burr-free finish which extends shaft life and allows for easier installation.
The collar is infinitely adjustable, providing flexibility in its application.
The acme threading allows for higher axial holding power than traditional threaded collars.
Top product applications:
Shaft alignment and positioning in machine tools and CNC equipment
Load bearing face in applications where precision is critical
Mechanical stops in precision machinery and equipment
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 two-piece acme threaded shaft collar has a 3/4" - 6 TPI bore, 1 1/2" OD, and 0.500" width. Threads are double tapped to ensure a burr-free finish which extends shaft life and allows for easier installation. Acme threading allows for higher axial holding power than traditional threaded collars. Tightly controlled face to bore perpendicularity is maintained (TIR of < 0.002") 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 one groove on the face allowing the user to easily identify which side is precision faced. The two-piece design allows this collar to be installed or serviced in-place without the need to remove adjacent components. Halves are mated throughout the manufacturing process for precise fit and increased holding power. 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 consistent corrosion resistance. Hardware tests beyond ANSI standards for maximum holding power. It is RoHS and REACH compliant.
