Balanced Shaft Collar, 2pc, Bore 1.8125", Steel, OD 2 7/8"

This two-piece shaft collar offers superior holding power and precision in high RPM applications. Its balanced design and tightly controlled face to bore perpendicularity make it ideal for use as a load bearing face, mechanical stop, or for component alignment. The collar's unique design allows for in-place installation and servicing, reducing downtime and increasing efficiency. Manufactured from lead-free steel with a fine burr-free finish and proprietary black oxide formulation, this shaft collar provides increased holding power and corrosion resistance. Suitable for use in a variety of industries, including aerospace, medical, and industrial automation.

Top product features:

  • 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.
  • The collar has a balanced design for better performance in high RPM applications.

Top product applications:

  • Load bearing face
  • Mechanical stop
  • Component alignment
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 1.8125" bore, 2 7/8" OD, and 0.688" width. It has a balanced design for better performance in high RPM applications. 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 1215 lead-free steel to a fine burr-free finish with Ruland's proprietary black oxide formulation which creates a fine glossy appearance and increases holding power and corrosion resistance. Hardware tests beyond ANSI standards for maximum holding power. It is RoHS and REACH compliant.
