  • TypeCouplings, Collars & Adapters
  • Precise 15 mm bore fits metric shafts
  • One-piece clamp design distributes holding force evenly
  • Carbon steel 1215 body resists wear in power-transmission use
  • Alloy-steel screw maintains clamping torque under vibration
  • 34 mm outside diameter keeps assembly compact

15 mm Metric Shaft Collar

This 15 mm bore clamp collar is made from 1215 carbon steel and uses an alloy steel screw for a secure grip on metric shafts. The one-piece construction simplifies installation in power transmission assemblies where a reliable axial stop or component spacer is required.

Suits metric shafting up to 15 mm

The 34 mm outside diameter and 13 mm width provide a compact clamping surface for light to moderate loads. Builders needing a two-piece split collar, a keyway-equipped bore, or a larger bore diameter should select a different style.

34 mm OD with 39.3 mm clearance diameter

The 13 mm collar width delivers adequate bearing surface for standard set-screw or clamp loading on 15 mm shafts. Applications requiring greater holding power, wider load distribution, or stainless steel construction will exceed the capacity of this model.

Questions about this item

What shaft diameter does the 15 mm bore fit?

The bore is 15 mm round, so it clamps directly onto a 15 mm shaft without a keyway.

Will the 34 mm outside diameter clear the bearing housing I already use?

The collar OD is 34 mm and the clamp screw swings to 39.3 mm clearance, so check that your housing pocket is wider than 39.3 mm.

How can I confirm the collar is seated correctly after tightening?

With the screw torqued, the 13 mm wide carbon-steel body should sit flush on the shaft and the alloy-steel screw head should not protrude past the 39.3 mm clearance diameter.
