Anti-corrosive shaft collars for harsh environments

Ruland Manufacturing Co., Inc. now offers shaft collars in both stainless steel and plastic to prevent corrosion in wet or harsh environments. These shaft collars are ideal for wash-down applications such as those found in food processing and marine applications. With typical steel collars, even those with a zinc or nickel finish, water, salt and other chemicals can have a detrimental effect on the performance of the collar. Ruland stainless steel shaft collars, with their passivated surface finish, resist water and many commercial grade chemicals, such as chlorine and some acids. Plastic collars from Ruland are made from acetal and offer similar surface protection to stainless steel. Both the stainless steel and plastic shaft collars are supplied with DIN 12.9 stainless steel screws that resist corrosion.

The collars are available in one- and two-piece clamp-style designs with bore sizes from 1/8" to 6" in the inch series and 3 mm to 80 mm in the metric series. Threaded bore collars are also offered with inch and metric threads. All Ruland shaft collars are single point faced to ensure perpendicularity and proper alignment. Ruland uses forged socket hardware in all its shaft collars, which allows for higher screw torque and increased holding power.

Shaft collars are part of Ruland’s complete product line which also includes rigid couplings and five types of zero-backlash motion control couplings: beam couplings, bellows couplings, oldham couplings, miniature disc couplings and curved jaw couplings.
