Ruland Shaft Collar, One Piece, Clamp, Bore 20mm, OD 40mm, W 31.6mm, Steel

The Ruland Shaft collar is commonly used for guiding, spacing, stopping, mounting, and component alignment. It is engineered with tightly controlled face-to-bore perpendicularity, which is critical for proper alignment when used as a load-bearing face, mechanical stop, or for mounting components such as gears or bearings. It is manufactured using proprietary processes to ensure a superior fit, high-quality finish, and strong holding power.
