Shaft Collar, 1pc Clamp, Bore 21mm, OD 42mm, Anodized Aluminum MPN:MCL-21-AN

This Ruland clamp style shaft collar is a precision-engineered component designed for applications where high accuracy and reliability are critical. Its one-piece construction and anodized aluminum material provide excellent strength and corrosion resistance, while the infinitely adjustable design ensures a secure hold on shafts without marring the surface. Suitable for use as a load bearing face, mechanical stop, or component alignment, this shaft collar is ideal for high-precision industries such as aerospace, medical devices, and automation. Its precision face and bore ensure reliable performance in demanding applications.

Top product features:

• 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.
• Hardware is stainless steel and tests beyond DIN 912 12.9 standards for maximum holding power.

Top product applications:

• Shaft Collar used as a load bearing face in a mechanical system
• Shaft Collar used as a mechanical stop in a precision machine
• Shaft Collar used for component alignment in a manufacturing process
