CLIMAX Metal Products C-243-BO Shaft Collar

This new shaft collar from Climax Metal Products is a single-piece carbon steel component designed for power transmission setups. It features a 2-7/16 inch round bore and a 3.5 inch outside diameter with a one inch width. The collar uses a set screw mechanism constructed from carbon steel grade 1211 for secure shaft attachment.

For maintenance teams securing shafts up to 2-7/16

Technicians needing a one-piece carbon steel collar with a set screw locking method will find this item suitable for inch-based systems. Buyers requiring a two-piece split design, a keyway feature, or a different bore diameter should look at alternative collar configurations not described here. The transparent finish and lack of keyway limit use to plain round shafts only.

Fits 2-7/16 in round shafts in power transmission

The collar mounts directly onto the shaft using the included set screw without additional tooling for split assembly. Its 3.5 inch clearance diameter determines the radial space needed around the shaft within the assembly. The one-piece construction frees up axial installation steps compared to two-piece styles but requires shaft end access for fitting.

Highlights

  • Precision fit for 2-7/16 inch shafts
  • Durable 1211 carbon steel construction
  • One-piece design simplifies installation
  • 5 inch outside diameter clears adjacent parts
  • Includes carbon steel set screw for secure hold

Questions about this item

What shaft diameter must I already have for the 2-7/16 in bore to fit?

The collar is bored for a 2-7/16 in round shaft; your shaft must match that exact diameter for the set screw to clamp properly.

Will the 3-1/2 in outside diameter clear the adjacent bearing housing I am keeping?

The collar’s outside diameter is 3-1/2 in, so measure the gap on your existing housing; if the space is at least that wide it will clear without interference.

How can I confirm the set screw is holding the collar fast after installation?

Tighten the carbon-steel set screw until the collar no longer rotates or slides on the shaft, then verify there is no axial play by pushing and pulling the collar by hand.
