Maximize performance and precision with Ruland's Balanced Collar, engineered for high RPM applications. This two-piece shaft collar features a 30mm bore and 54mm OD, with a balanced design for superior holding power and minimal shaft marking. The tightly controlled face to bore perpendicularity ensures accurate load bearing, mechanical stops, and component alignment. With a fine burr-free finish and high-strength 2025 aluminum construction, this collar provides increased screw seating torque and meets or exceeds DIN 912 12.9 standards. Ideal for use in machinery, equipment, and automation, this collar delivers reliable performance and long-lasting durability in a wide range of industries.
Top product features:
The collar is infinitely adjustable.
The collar has superior holding power when compared to set screw collars.
The collar has tightly controlled face to bore perpendicularity of less than 0.05mm.
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 shaft collar has a 30mm bore, 54mm OD, and 15mm width. It has a balanced design for better performance in high RPM applications. 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. 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 high strength 2025 aluminum to a fine burr-free finish for increased screw seating torque. Hardware tests beyond DIN 912 12.9 standards for maximum holding power. It is RoHS and REACH compliant.
