Ruland SHAFT COLLAR MCL-4E-SS

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 0.2500" bore, 18mm OD, and 9mm 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 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.
