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 two-piece keyed shaft collar has a 3.0000" bore, 3/4" keyway, 4 1/4" OD, and 0.875" width. It is designed for use with keyed shafting and in applications where the collar may be used for positive drive. 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 303 stainless steel to a fine burr-free finish with hardware of like material for consistent corrosion resistance. Hardware tests beyond ANSI standards for maximum holding power. It is RoHS and REACH compliant.
