Washdown shaft collars from Ruland help protect hygienic equipment from bacterial contamination. Washdown shaft collars feature a patent pending assembly containing a type 303 stainless steel shaft collar, a two-piece housing made from FDA compliant materials, and three O-rings with NSF H1 registered lubricant. Applications in the food processing, packaging, and medical industries benefit from the reduced risk of bacterial growth.

Hot spots on traditional shaft collars such as saw cuts, screw pockets, and surface imperfections may allow bacteria to grow and spread within the system. These spots can be difficult to clean and are not always accessible. Washdown shaft collars eliminate these hot spots and provide a smooth uninterrupted surface for easy cleaning, making them a safer alternative to standard shaft collars.

Washdown collars function similar to traditional shaft collars as guides, spacers, positioners and hard stops. They offer holding power comparable to clamp style shaft collars and allow for simple adjustments without marring the shaft. Ruland’s exclusive design is pending an IP69K rating against the ingress of dust and water up to 80°C and 8 to 10 MPa of pressure.

Washdown shaft collars are supplied with a zinc-plated forged alloy screw for maximum holding power and are available for shaft sizes ranging from 1/4 ” to 1 ” or 6 mm to 25 mm.

Washdown shaft collars are part of Ruland’s complete shaft collar line which also includes quick clamping shaft collars, one- and two- piece clamp style shaft collars, threaded, bearing locknut, heavy duty, double wide, and set screw shaft collars. Ruland also manufactures rigid couplings with precision honed bores and a full line of zero backlash couplings: beam, bellows, disc, jaw, and oldham. All products are carefully manufactured in Ruland’s factory in Marlborough, Massachusetts, USA, under strict controls using proprietary processes.
