Sheave products are essential components in various industrial applications, providing reliable performance for lifting, rigging, and mechanical power transmission systems. Our high-quality sheaves are designed to meet the toughest demands while ensuring smooth operation and extended service life.
Our sheave products offer superior performance with these key features:
| Model | Diameter (inches) | Groove Type | Max Load (lbs) | Weight (lbs) |
|---|---|---|---|---|
| SHE-100 | 4 | V-Groove | 2,000 | 3.5 |
| SHE-200 | 6 | U-Groove | 4,500 | 7.2 |
| SHE-300 | 8 | Flat-Groove | 8,000 | 12.8 |
| SHE-400 | 10 | Double-Groove | 12,000 | 18.5 |
Q: What is the recommended maintenance schedule for sheaves?
A: Sheaves should be inspected monthly for wear and damage. Lubricate bearings every 3 months or after 500 operating hours. Complete disassembly and thorough inspection should be performed annually or after 2,000 operating hours.
Q: How do I select the correct sheave size for my application?
A: The sheave diameter should be at least 20 times the diameter of the wire rope for optimal performance and rope life. Consider the working load limit, rope type, and environmental conditions when selecting your sheave.
| Feature | Standard Sheave | Premium Sheave |
|---|---|---|
| Material | Carbon Steel | Alloy Steel/Stainless Steel |
| Bearing Type | Bronze Bushings | Sealed Ball Bearings |
| Corrosion Resistance | Basic | High (Galvanized/Stainless) |
| Service Life | 2-3 years | 5-7 years |
Q: What are the signs that a sheave needs replacement?
A: Common indicators include visible cracks or chips, excessive groove wear (more than 10% of rope diameter), bearing play exceeding manufacturer specifications, or any deformation that affects rope alignment.
Q: Can sheaves be used with both wire rope and synthetic rope?
A: While some sheaves are designed for dual-purpose use, we recommend using specific sheaves designed for each rope type. Wire rope sheaves typically have deeper grooves, while synthetic rope sheaves often feature smoother surfaces to prevent fiber damage.
Q: How does sheave material affect performance in different environments?
A: Carbon steel sheaves work well in standard conditions but may corrode in wet or chemical environments. Stainless steel offers superior corrosion resistance for marine or chemical applications. Alloy steel provides the best strength-to-weight ratio for heavy-duty applications.
Q: What is the advantage of using sheaves with sealed bearings?
A: Sealed bearings prevent contamination from dirt, dust, and moisture, significantly extending service life and reducing maintenance requirements. They're particularly beneficial in harsh environments where frequent relubrication would be difficult.
