Features of Double Split Shaft Collar
Two Pieces Split Shaft Collar Title:
steel & aluminum double split shaft collars custom shaft collar with keyway for positioning bearings
The locking clamp collar achieves ± 0.01mm radial runout control through a dual split structure, synchronously solving the axial displacement problem of traditional clamping collars;
Advantages of clamping shaft collars:
The Heavy Duty Double Split Shaft Collar is made of forged 420 stainless steel, 304 stainless steel, and nickel plated carbon steel, with a variety of material options, and a tensile strength of up to 1200MPa. Double split design combined with 12.9 level hex screws, providing a large aperture range of 25mm-150mm, with optional phosphating or Dacromet treatment on the surface to meet extreme environmental requirements.
The Sanitary Double Split Shaft Collar can be fully mirror polished, and the double split ring body is made of 316L stainless steel integrated molding. The sealing groove design of the clamping collar is specially optimized, suitable for GMP scenarios such as pharmaceutical filling equipment and dairy pumps;
