When looking for a Sheave manufacturer, customers are typically focused on the durability of the product. With our Sheaves at Loos & Co., Inc., our products consistently meet the need for durability and reliability, as our expertise and manufacturing capabilities are unmatched across the industry. Â
As the Wire Rope Industry Choice for all your Sheave needs, we know what challenges your Sheave applications may put on the product. Although Steel and Aluminum Sheaves are a common choice, you may want to choose a Cast Nylon material to ensure the durability, reliability and performance you’re looking for. Â
Continue reading to learn about some of the advantages of replacing Steel and Aluminum Sheaves with Cast Nylon. Â
Choosing Cast Nylon over Steel or Aluminum
Many Sheave uses can be physically demanding, such as hoists, cranes or other load bearing applications. Although for many years Steel and Aluminum Sheaves were the choice for these applications, most customers have made the switch to Cast Nylon instead. Â
Cast Nylon Sheaves offer an alternative that is lightweight and durable while improving the service life of the Wire Rope or Cable running through it. Â
Here’s a few reasons why customers are switching to Cast Nylon Sheaves.Â
1. Durability
In hoisting and lifting applications, durability is crucial to avoid severe wear and tear due to repeated use. Our Cast Nylon Wire Rope Sheaves have a unique combination of physical properties that contribute to their durability. Â
They have high tensile and compressive strength, to go along with high elongation properties which drastically improve the product’s life span. Â
Cast Nylon Sheaves also possess additional features that improve durability such as a cushioning effect in the groove areas that contact the rope strands, reduced contact pressure at the rope-groove interface and near-elimination of any wear on the outer layer of the Wire Rope strands. Â
These qualities not only provide excellent durability, but also increase operational safety and extend Wire Rope life by two to three times that of Aluminum and Steel Sheaves. Â
2. Significantly Lighter than Steel & Aluminum Sheaves:
Both ease of installation and overall performance are helped by the fact that Cast Nylon Sheaves are a much lighter product than Aluminum or Steel. Â
They are about 1/7th the weight of Steel Sheaves of the exact dimensions and approximately half the weight of Aluminum Sheaves. The lightweight properties of Cast Nylon Sheaves result in:Â
- Reduced dead weightÂ
- Increased working capacityÂ
- Lower inertial loads in operationÂ
- Ease handling during installation and replacementÂ
3. Protection Against Rust and Saltwater Corrosion:
Many Sheave applications involve threats of rust or corrosion over time. Â
While Steel Sheaves easily rust, our Cast Nylon Sheaves are impervious to rust and saltwater corrosion. Nylon is a naturally corrosion-resistant material, so there is no need to rely on the integrity of a thin coating or paint to protect the Sheave.  Â
Cast Nylon Sheaves eliminate the need for surface maintenance, and as nylon cannot rust, the strength and lifetime of our Sheaves are vastly better than those made with steel. Â
4. Variety of Customization Options:
Our suppliers have hundreds of molds to fit almost every rope sheave requirement, so by choosing eSheaves you are guaranteed to find exactly what you need! Nuestra HardHatâ„¢ Sheaves are produced in molds custom engineered to the application, meaning that material properties are optimized, and casting stresses are eliminated, resulting in a superior component.Â
