Shaft Collar, 1pc Clamp, Bore 0.5000", OD 30mm, Anodized Aluminum

Description

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 one-piece international series shaft collar has a 0.5000" bore, 30mm OD, and 11mm width. International series collars have metric outer diameter and width dimensions. They are supplied with a metric screw allowing users to have an inch bore collar that can be installed with metric tools. 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. This collar is stamped with the Ruland name and bore size for ease of identification. It is manufactured from high strength 2025 black anodized aluminum to a fine burr-free finish for light corrosion resistance. Hardware is stainless steel and tests beyond DIN 912 12.9 standards for maximum holding power. It is RoHS and REACH compliant.
