PRODUCT SPECIFICATIONS

Ruland SC-18-F is a set screw shaft collar with a 1.1250" bore, 1 3/4" OD, and 0.625" width. It is commonly used for guiding, spacing, stopping, and component alignment in light duty applications where the collar is infrequently repositioned or removed. Holding power is derived from the screw as it is tightened onto the shaft. In order for the collar to obtain maximum holding power the shaft must be softer than the material of the screw. Proprietary processes have been developed by Ruland to maintain superior fit, finish, and holding power. SC-18-F is stamped with the Ruland name and bore size for ease of identification. The forged screw tests beyond ANSI standards to ensure maximum holding power. SC-18-F is manufactured from solid bar stock sourced from select North American mills and machined to a fine burr free finish. Ruland uses 1215 lead-free steel with a proprietary black oxide finish that produces a fine glossy finish while increasing holding power and resisting corrosion. SC-18-F is RoHS3 and REACH compliant and manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
