Ruland manufactures 303 and 316 stainless steel shaft collars to meet the demanding needs of marine and subsea applications that are exposed to the harsh ocean environment. Applications found in AUVs, ROVs, seismic activity detection, tidal power and deep sea drilling equipment benefit from superior fit, finish, and holding power offered by Ruland shaft collars.

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. Ruland 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.

Ruland offers 303 and 316 stainless steel shaft collars in one- and two-piece clamp styles with bore sizes ranging from 1/8” (3 mm) to 3” (80 mm). Clamp style shaft collars have high holding power, do not mar the shaft, and allow for simple positioning adjustments. Ruland shaft collars have tightly controlled face to bore perpendicularity of TIR <0.002” (0.05 mm). They are stamped with the Ruland name and bore size for ease of identification. Two-piece styles are mated throughout the manufacturing process to ensure proper fit and alignment. Both 303 and 316 stainless steel shaft collars from Ruland are supplied with hardware of like material for consistent corrosion resistance.

The complete range of Ruland shaft collars include one- and two-piece clamp styles with smooth or threaded bores in 1215 lead free steel, 303 stainless steel, 316 stainless steel, 2024 aluminum, zinc plated steel, and engineered plastic. All Ruland products are RoHS2 and REACH compliant.
