The Ruland Balanced Collar is a precision-engineered shaft collar designed for demanding applications. Its balanced design ensures superior performance in high-RPM applications, while its two-piece construction allows for easy installation and servicing in-place. The collar features a 80mm bore, 108mm OD, and 19mm width, with tightly controlled face-to-bore perpendicularity for critical load-bearing, mechanical stop, or component alignment applications. Manufactured from 303 stainless steel for corrosion resistance, this collar offers superior holding power and meets DIN 912 12.9 standards. Ideal for use in aerospace, medical devices, and other industries requiring high precision and reliability.
Top product features:
The collar is infinitely adjustable.
It has superior holding power compared to set screw collars.
It 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 80mm bore, 108mm 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 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.
