This Ruland Left Hand Threaded Collar is a precision-engineered component designed for demanding applications. Its M30 x 3.5 bore and 54mm OD provide a secure fit on shafts, while the left-hand threading offers safety and flexibility. The collar's one-piece design and double-tapped threads ensure a burr-free finish and superior holding power. Ideal for use as a load-bearing face, mechanical stop, or component alignment, this collar maintains tightly controlled face-to-bore perpendicularity. Made from 303 stainless steel, it offers consistent corrosion resistance and exceeds DIN 912 12.9 standards for holding power, making it suitable for use in harsh environments and critical applications.
Top product features:
Left-hand threading prevents the unintended removal of critical components.
This one-piece collar is infinitely adjustable, allowing for precise fitting to the shaft.
Threads are double tapped to ensure a burr-free finish, extending shaft life and making installation easier.
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 left hand threaded shaft collar has an M30 x 3.5 bore, 54mm OD, and 15mm width. Threads are double tapped to ensure a burr-free finish which extends shaft life and allows for easier installation. Threaded collars allow for higher axial holding power than traditional round bore types. Left hand threading is commonly used when right hand threading is not feasible or for safety to prevent the unintended removal of critical components. 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 consistent corrosion resistance. Hardware tests beyond DIN 912 12.9 standards for maximum holding power. It is RoHS and REACH compliant.
