Where a rotating shaft meets its seal, a battle of friction is constantly waged. In standard setups, this interface is the first to score, pit, and fail. The Ceramic Coating Shaft Sleeve is our premier armor for these high-wear zones. Utilizing Atmospheric Plasma Spray (APS) technology, we deposit a high-density ceramic shield—such as Chrome Oxide or Zirconia—onto a precision-machined core. The result is a surface so sleek and hard that it drastically reduces friction against mechanical seals, turning a vulnerable point of failure into a fortress of reliability.
Diamond-Like Hardness: Achieves surface hardness levels up to HV 1300, far exceeding hardened steel alloys.
Seal Life Extension: The ultra-smooth Ra 0.2 finish minimizes heat generation and lip-seal hardening.
Zero-Leakage Barrier: High-velocity deposition creates a dense, low-porosity seal that prevents subsurface corrosion.
Thermal Integrity: Engineered to remain dimensionally stable even under intense thermal cycling and frictional heat.
In papermaking, board production, and composite coating lines, the sizing roll is a core component that controls the uniformity of the adhesive layer. Conventional chrome-plated or rubber rolls, which are constantly exposed to adhesives, moisture, and filler particles, are highly prone to wear, corr
