Anti-Galling Clamp

If galling occurs on a sanitary clamp, the nut and bolt fuse together so operators can’t easily remove the clamp. In fact, operators may have to cut off the clamp to remove it, which often causes delays and disruptions to the manufacturing process. Anti-galling clamps are designed to prevent the adhesion of materials due to friction and to keep critical processes running smoothly.

LJ Star offers a full line of Anti-Gall Clamps that are produced to the highest hygienic engineering standards and are constantly being updated in response to customer feedback and industry requirements. The nut and bolt are made of dissimilar materials so that adhesion, or galling, is less likely to occur.

Anti-Galling Clamps are available in a variety of materials, including 304 and 316 stainless steel. With higher quality and durability than lower-grade stainless, 316 stainless is ideal for demanding applications, including pharmaceutical, food/beverage and biotech.

Like all sanitary clamps offered by LJ Star, Anti-Galling Clamps are BPE compliant, which means they meet one of the highest hygienic engineering standards. Since all LJ Star sanitary clamps can be made with anti-galling characteristics, the company can create a customized clamp to suit the unique requirements of any critical processing application.

A patented Anti-Galling Safety Clamp is available for processes that have a vibration or a pressurized line. The half-threaded bolt on this safety clamp keeps the clamp in place and helps minimize safety issues.

LJ Star offers tips for training and preventive maintenance to help operators maximize the performance of their sanitary clamps. Free product samples are also available.
