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

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 acetal plastic to a fine burr-free finish for use in light duty applications where corrosion resistance is required. Hardware tests beyond DIN 912 12.9 standards for maximum holding power. It is RoHS and REACH compliant.
