This Ruland balanced collar features a two-piece design with a 48mm bore, providing superior holding power and infinite adjustability. Its balanced design enables better performance in high RPM applications, while tightly controlled face to bore perpendicularity ensures precise alignment and load bearing capabilities. The collar's precision-finished work surface and fine burr-free finish increase screw seating torque. Ideal for use as a mechanical stop, load bearing face, or component alignment, this collar is suitable for a wide range of industries, including aerospace, medical, and automation. Its durable 2025 aluminum construction and high-strength hardware ensure reliable performance in demanding environments.
Top product features:
Infinitely adjustable
Does not mar the shaft
Maintains tightly controlled face to bore perpendicularity (TIR of < 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 48mm bore, 78mm OD, and 19mm 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.
