New from Ruland: Clamp Style Shaft Collars

Ruland Manufacturing Co., Inc.

Clamp style shaft collars from Ruland (from left to right):One-piece shaft collar, two-piece shaft collar, and quick clamping shaft collar.Shaft collars are one of the most versatile machine components with a variety of uses including positioning, guiding, stopping, clamping, and spacing. To overcome common problems with set screw shaft collars, Ruland offers one-piece, two-piece, and quick clamp style shaft collars.

Unlike set screw style collars, clamp style shaft collars 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. Quick clamping shaft collars were engineered by Ruland with a low profile clamping lever which is operated by hand without the need for tools.

Clamp style shaft collars are machined to maintain a precise face to bore perpendicularity for proper alignment. This is important for many applications where components such as bearings need to be aligned on the shaft to prevent unnecessary wear. Ruland’s black oxide finish, carefully selected hardware, and additional proprietary processes help to ensure a superior fit, finish, and holding power.

The shaft collars are manufactured from carefully sourced aluminum, lead-free steel, stainless steel, and engineered plastic. Threaded, double wide, and heavy duty clamp style shaft collars are also available with bore sizes ranging from 1/8” to 6” and 3mm to 150mm depending on style.

The products are manufactured in Ruland’s Marlborough, Massachusetts factory under strict controls using proprietary processes. Shaft collars are part of Ruland’s total product offering which also includes rigid couplings and five types of motion control couplings: beam, bellows, disc, oldham, and zero backlash jaw.
