Now available from Techdrives are Ruland’s one-piece, two-piece, and quick clamp style shaft collars. According to the company, these are easy to remove, infinitely adjustable, and will not mar the shaft. One-piece collars distribute compressive forces evenly around the shaft for a tight fit and improved holding power. With an additional screw, the two-piece collar has superior holding power and can be installed without removing other components.
Of benefit, these are machined to maintain a precise face to bore perpendicularity for proper alignment, a benefit where components such as bearings need to be aligned on the shaft to prevent unnecessary wear.
