Precision-machined from high polymer nylon, this Lebus grooved sleeve (model DN10-D400-L897) is specifically designed for 10 mm wire rope spooling applications. The sleeve features a segmented groove architecture comprising a 90° parallel section, a 55° right-handed helical crossover, a 125° parallel section, a second 55° helical segment, and a final 35° parallel section. This complex pattern achieves an overall length of 897 mm with a -0.3 mm tolerance. Defined by a 9.8 mm pitch and 91.5 groove turns, the geometry ensures consistent rope layering across the drum face. As a non-metallic replaceable liner, it protects the parent drum while delivering smooth, low-friction spooling performance.

Unlike conventional steel drum liners, this high polymer nylon sleeve offers inherent corrosion resistance and self-lubricating properties that reduce wire rope abrasion. The multi-segment Lebus groove profile begins with a 90° parallel section for stable rope seating, transitions through a 55° helical zone for smooth layer crossover, then passes through a 125° parallel section for consistent tension distribution, followed by a second 55° helical segment and a final 35° parallel section. The 9.8 mm pitch is precisely calibrated to 10 mm rope characteristics, minimizing friction and wear on both components. As a replaceable bolted liner, it allows operators to restore original grooving accuracy without scrapping the entire drum assembly, dramatically lowering long-term maintenance expenses.
This nylon Lebus grooved sleeve is ideal for lightweight to medium-duty lifting equipment that requires controlled multi-layer winding of 10 mm wire rope. Typical applications include small marine winches, tower crane hoist mechanisms, automated material handling systems, and food-processing hoists where corrosion resistance is essential. The segmented groove pattern proves particularly effective in applications where the rope experiences variable fleet angles during operation, such as on shipboard davits and compact industrial winches. The non-metallic construction also eliminates sparking risks in explosive atmospheres. For maintenance teams and OEMs seeking a durable, precision-machined drum liner that combines low weight, corrosion resistance, and consistent spooling performance, this nylon sleeve offers a proven alternative to steel.
