Ruland SPB-3-P, 3/16" Balanced Shaft Collar, Plastic, Two-Piece Clamp Style, 5/8" OD, 0.281" Width
PRODUCT SPECIFICATIONS
Ruland SPB-3-P is a two-piece shaft collar with a 3/16" bore, 5/8" OD, and 0.281" width. It has a balanced design with opposing screws for use in high RPM applications such as those found in motors and gearboxes. The clamp style design does not mar the shaft, is easy to remove, and is indefinitely adjustable. SPB-3-P is commonly used for guiding, spacing, stopping, mounting, and component alignment. Equipment manufacturers benefit from the tightly controlled face to bore perpendicularity (TIR of ≤ .002"). Perpendicularity is critical for alignment when the shaft collar is used as a load bearing face, mechanical stop, or for mounting components such as gears or bearings. Proprietary processes have been developed by Ruland to maintain superior fit, finish, and holding power. SPB-3-P is stamped with the Ruland name and bore size for ease of identification. Halves are mated throughout the manufacturing process for proper fit and alignment. Forged screws test beyond ANSI standards to ensure maximum holding power. SPB-3-P is machined from solid bar stock to a fine burr free finish and sourced exclusively from North American mills. Ruland uses engineered acetal plastic for a consistent finish. It is RoHS2 and REACH compliant and manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
