Answer (from Ningbo Changshi): The material of the sheave (the wheel of the roller) is a crucial consideration that impacts a project's safety and success. We offer sheaves made from two high-quality materials:

• MC Nylon Sheaves: These are highly recommended for protecting the conductor. The non-conductive and low-friction properties of nylon prevent scratching or damage to the conductor's surface, which is especially important for delicate or insulated cables. They are also lighter than steel, making them easier to handle and install.

• Steel Sheaves: Known for their exceptional strength and durability, steel sheaves are ideal for handling very heavy conductors and for projects where the ultimate load-bearing capacity is the main concern.

Both types are designed for reliability, but the choice between them often depends on the specific conductor type and project requirements. Our products are engineered to provide maximum performance regardless of the material.
