  • TypeBearings, V-belts & Power Transmission Equipment
  • ColorTransparent
  • One-piece carbon-steel collar clamps securely without marring the shaft
  • 4 in round bore fits standard inch-dimension shafts directly
  • 44 in clearance diameter clears adjacent components easily
  • 7/8 in width provides rigid axial location in tight spaces
  • Grade 1211 carbon steel delivers consistent strength and wear resistance

Shaft Collar for 4 in Round Bore

This one-piece clamping collar fits a 4 in round bore and is made from 1211 carbon steel. The 1-Piece construction uses a carbon steel screw to secure the collar directly onto the shaft. It is supplied new and ships directly from the distributor.

Build Quality and Mounting Implications

The collar has a 5 1/4 in outside diameter and a 5.44 in clearance diameter, providing a compact profile for power transmission assemblies. A 7/8 in collar width distributes clamping force across the shaft surface. The transparent finish allows visual inspection of the contact area during routine checks.

Upgrade Path and Fitment Limits

This collar replaces split or two-piece collars where a single-piece design simplifies installation and reduces component count. The jump is worth it when a solid 1211 carbon steel ring with integral screw is preferred over multi-part alternatives for inch-measurement shafts. Buyers who need a keyway or threaded bore cannot use this model.
