Sheaves
Cast Sheaves
This comprehensive datasheet contains the primary technical tables for Ropeblock’s standard SE series cast sheaves equipped with cylindrical roller bearings. It covers an extensive size range, from tread diameters of 8.86 inches up to massive 104.72-inch units. For each model, it specifies shaft sizes, compatible wire rope diameters, groove radii, and bearing types (typically SL04 series), providing engineers with the data needed for large-scale industrial and maritime hoisting systems.
Engineered for Precision & High-Performance Wire Rope Guidance
The Cast Sheave with Cylindrical Roller Bearings offers a robust and reliable solution for high-capacity crane blocks and rigging systems where smooth rotation and wire rope longevity are non-negotiable. These precision-machined sheaves are designed to minimize friction and wear, providing superior load guidance in critical industrial and marine lifting environments.
Maximum Safety Features
- Standard-Certified Bearings: Equipped with high-quality cylindrical roller bearings (standard SL04 or optional ZZ/NJ series) for maximum radial load capacity.
- Material Integrity: Body manufactured from high-grade cast material to withstand the extreme pressures of heavy-duty wire rope operation.
- Verified Dimensions: All critical dimensions, including tread diameter (D2) and groove radius (R), are indicative and verified via technical drawings prior to production.
- Comprehensive Safety Standards: Designed in alignment with rigorous industrial crane group standards to ensure operational reliability.
Industrial Flexibility
- Extensive Size Range: Available in sheave tread diameters ranging from 8.86 inches to 104.72 inches to accommodate diverse crane block configurations.
- Wire Rope Versatility: Precision-engineered grooves tailored for wire rope diameters from 0.39 inches up to 2.95 inches.
- Bearing Versatility: Compatible with various bearing widths and shaft sizes (øG) to meet specific mechanical overhaul requirements.
- Custom Engineering: Standard models are showcased, but inquiries for custom diameters, groove radii, or specialized materials are welcome to meet unique project specifications.
