These 303 and 316 stainless steel shaft collars meet the demanding needs of marine and subsea applications exposed to the harsh ocean environment, such as AUVs, ROVs, seismic activity detection, tidal power and deep sea drilling equipment.

Type 303 stainless steel is best suited for above water applications where the shaft collar can be regularly cleaned while 316 stainless steel is best suited for subsea applications that require high levels of corrosion resistance. The shaft collars are machined to a fine surface finish free of pits and other major imperfections that can lead to premature corrosion and failure. All material is sourced from carefully selected North American mills.

The stainless steel shaft collars in one- and two-piece clamp styles have bore sizes ranging from 1/8 in. (3 mm) to 3 in. (80 mm). Clamp style shaft collars have high holding power, do not mar the shaft, and allow for simple positioning adjustments. These collars have tightly controlled face to bore perpendicularity of TIR <0.002 in. (0.05 mm). Two-piece styles are mated throughout the manufacturing process to ensure proper fit and alignment.
