Cast Sheaves Rigging With Cylindrical Roller Bearings
This datasheet outlines technical specifications for rigging-specific cast sheaves (SEF series) utilizing high-capacity cylindrical roller bearings. It covers models from 4.72 inches to over 40 inches in tread diameter. The detailed tables include dimensions for outer diameter, rim width, and bearing width, emphasizing structural robustness for demanding rigging environments where high line pulls are expected.
Engineered for Precision & High-Performance Rigging
The Cast Rigging Sheave with Cylindrical Roller Bearings is a high-productivity solution designed for critical rigging applications where smooth rotation and superior load transfer are non-negotiable. Featuring a precision-machined cast body and double-sealed roller bearings, these sheaves provide exceptional stability and durability in heavy-duty structural and maritime environments.
Maximum Safety Features
- High-Performance SL Bearings: Standard factory supply includes high-capacity SL04 Cylindrical Roller Bearings (PP type) for maximum radial load support.
- Material Integrity: Manufactured from premium cast material, providing a robust and fatigue-resistant body for high-load cycles.
- Precision Load Path: Optimized groove radii ensure proper wire rope seating, reducing wear and preventing premature rope failure.
- Safety Standard Compliance: Engineered in alignment with comprehensive safety documentation and crane group requirements.
Industrial Flexibility
- WLL & Sizing Range: Available in sheave tread diameters from 4.72 inches up to 40.16 inches to suit various industrial rigging blocks.
- Custom Shaft Integration: Versatile design allows for different shaft sizes (øG) to meet specific mechanical overhaul requirements.
- Adjustable Wire Groove: The groove radius (R) can be precision-adjusted to accommodate specialized or non-standard wire rope diameters.
- Interchangeable Bearings: Compatible with multiple bearing widths and seal types for specialized construction or marine rigging needs.
