Designed for 26 mm wire rope applications, this split drum liner features a double cross-cut Lebus groove configuration with a left-handed 80° lead angle. The segmented geometry is built around a 27 mm pitch and 27 groove turns (Z), delivering an overall length of 729 mm with a -0.5 mm tolerance. Both ends are fitted with welded lead-in ramps that promote smooth rope entry and exit, reducing impact wear during start-stop cycles. A gray zinc-rich primer finish provides corrosion resistance, making this sleeve suitable for demanding marine and industrial environments.

This drum liner stands out with its double cross-cut Lebus groove pattern, which offers superior layer-to-layer transition stability compared to conventional single-start designs. The left-handed 80° lead angle is precisely tuned for moderate fleet angle conditions, ensuring controlled spooling without rope overlap. Welded entry and exit ramps eliminate sharp transitions, significantly reducing rope wear during acceleration and deceleration. The 27 mm pitch and 27 groove turns maintain consistent alignment across the full 729 mm length. A gray zinc-rich primer coating protects against corrosion in saltwater and humid environments. Every unit is deburred and held to GB/T 1804-2000 tolerances, guaranteeing reliable fit and long-term performance.
