Black oxide steel step-up adapter clamp with 5/8 inch bore

Climax Metal Products

Climax Metal Products SUA-062 Step Up Adapter Clamp On Bore 5/8 in

SKU CH-TVX9-KZTH1

A steel step-up adapter clamps onto a 5/8 in bore and provides a 7/8 in shaft with black oxide finish

  • Steps up shaft diameter from 5/8 in bore to 7/8 in shaft
  • Precision bore tolerance +0.003/-0.000 ensures accurate fit
  • Black oxide finish on ASTM A108 steel resists corrosion
  • Hardened ASTM A574 steel set screw secures connection
  • Compact 3-1/4 in overall length fits tight spaces

Build-Ready Step-Up Adapter

The Climax Metal Products SUA-062 is a clamp-on step-up adapter machined from ASTM A108 steel with a black oxide finish. It accepts a 5/8 in bore with a +0.003/-0.000 tolerance and a 1 3/8 in bore depth. The 7/8 in shaft diameter carries a -0.000/-0.003 tolerance for precise fit in power transmission assemblies.

Secures With Standard Hardware

A single 10-32 set screw made from ASTM A574 steel locks the adapter onto the shaft using a 1/2 in screw length. The 1 1/2 in outside diameter and 1 1/2 in shaft length allow the unit to bridge smaller shafts to larger hubs without requiring a custom spacer or keyway modification.

Holds Tolerance Under Load

The opposing bore and shaft tolerances maintain concentric alignment when torque is transmitted continuously. Black oxide coating resists surface corrosion in shop environments while the alloy steel construction resists deformation under sustained radial and axial forces.

Highlights

  • Steps up shaft diameter from 5/8 in bore to 7/8 in shaft

  • Black oxide finish on ASTM A108 steel resists corrosion
  • Hardened ASTM A574 steel set screw secures connection
  • Compact 3-1/4 in overall length fits tight spaces

Questions about this item

How much clearance does the 10-32 set screw need before it bottoms out?

The set screw is 1/2 in long, so it requires at least that depth of thread engagement to reach full clamping force.

How much heat does the black-oxide steel body absorb during continuous rotation?

The adapter is solid steel with a black-oxide finish and has no internal friction surfaces, so it does not generate measurable heat under normal power-transmission loads.

What shaft diameter must the driven component have to match the 7/8 in step-up shaft?

The driven component needs a 7/8 in bore with a tolerance of -0.000/-0.003 in to fit the step-up shaft correctly.
