| High Light | Left-handed Lebus groove rope sleeve ，80° split LBS sleeve ，26mm wire rope drum sleeve | ||
This rope drum sleeve is manufactured for 26 mm wire rope applications, featuring a double cross-cut Lebus groove pattern with a left-handed 80° lead angle. This drum liner incorporates a segmented structure defined by 27 mm pitch (P) and 27 layers (Z), achieving an overall length of 729 mm with a -0.5 mm tolerance. The assembly includes welded lead-in ramps at both ends to facilitate smooth rope entry and exit. Finished with gray zinc-rich primer, this drum sleeve offers corrosion resistance and durable service in demanding environments.

This drum sleeve utilizes a double cross-cut Lebus groove geometry, which differs from standard single-start Lebus designs by providing a more stable transition between rope layers. The 80° left-handed lead angle is calibrated to optimize spooling under moderate fleet angle conditions. Welded ramps at both ends eliminate abrupt edges, reducing rope wear during startup and shutdown. The segmental layout, defined by 27 mm pitch, ensures consistent groove alignment across the full 729 mm length. Finished with gray zinc-rich primer, this drum liner resists corrosion in marine and industrial environments. Each unit is deburred and manufactured to GB/T 1804-2000 tolerances for reliable fit and performance.
This drum sleeve is well-suited for port machinery, shipboard cranes, and industrial winches where 26 mm wire rope is used in multi-layer winding systems. The double cross-cut Lebus groove pattern makes it particularly effective in applications requiring controlled rope layering without additional compression devices. Welded ramps at both ends allow for smooth rope transition, reducing impact stress during directional changes. Typical deployments include mooring winches, offshore lifting equipment, and material handling systems. Its replaceable design enables quick field maintenance, minimizing downtime. For operations demanding consistent spooling performance and corrosion protection, this drum sleeve delivers a practical, long-lasting solution.
