CK45 Skived and Roller Burnished Tube
A CK45 Skived and Roller Burnished Tube refers to a precision hydraulic cylinder tube made from CK45 steel, which has been skived and roller burnished on the inner surface. Here’s what that means in detail:
CK45 Steel
- Material type: Medium carbon steel (approximately 0.45% carbon content).
- Properties: Good machinability, high strength, and good wear resistance.
- Common uses: Hydraulic cylinder components, shafts, automotive parts.

Skived and Roller Burnished
- 1. This is a finishing process for the inside diameter (ID) of the tube.
- 2. Skiving removes a thin layer of material to create a smooth and accurate bore.
- 3. Roller Burnishing then compresses the surface to increase hardness, reduce roughness, and improve surface finish.
Benefits
- High dimensional accuracy (tight tolerances)
- Improved surface roughness (often ≤ Ra 0.2 µm)
- Enhanced fatigue and wear resistance
- Ready for use as a cylinder barrel (no further honing needed)

Typical Applications
- Hydraulic and pneumatic cylinder barrels
- Industrial machinery
- Mobile equipment
