SKU CH-8M53-Q8T8B

A two-piece clamp collar with 3/8 in bore and 7/8 in outside diameter, made from 303 stainless steel for corrosion resistance

  • Two-piece design allows installation without shaft removal
  • 303 stainless steel resists corrosion in harsh environments
  • 3/8 in bore fits standard inch-dimension shafts
  • 03 in clearance diameter clears adjacent components
  • 11/32 in width provides secure clamping force

Precision 3/8 inch Shaft Collar

The Ruland Manufacturing SP-6-SS is a two-piece clamp shaft collar machined from 303 stainless steel. It fits a 3/8 inch round bore and provides a secure, concentric grip on precision shafts without marring the surface. The 11/32 inch width and 7/8 inch outside diameter suit compact assemblies in instrumentation and light-duty drives.

Maintenance Teams and OEM Builders

Maintenance teams value the split design for quick installation or inspection without dismantling adjacent components. The 303 stainless material resists corrosion in wash-down or humid environments. Builders who need a keyway for torque transmission or a larger bore for heavier shafts should look at alternative collar styles.

1.03 inch Clearance Diameter

The 1.03 inch clearance diameter determines whether the collar clears adjacent bearings, housings or sensor brackets in your assembly. Verify this envelope against your layout drawings before ordering to ensure proper fit and free rotation of surrounding parts.
