Sheaves For Sawmills

Posted by on August 2, 2017

While not an application unique to sawmills, nylon sheaves bring the same benefits and advantages to sawmill applications as they do to any other industry. Plastic sheaves are long-lasting, lightweight, easy to install, and excel in high-load, low RPM applications. Another advantage of nylon sheaves is that the sheave itself can serve as a bearing: it is usually not necessary to procure and insert aftermarket bearings. Nylon sheaves have a high-load bearing capacity of 4,000 PSI and are available with a variety of fillers, such as oil and molybdenum disulphide aka “moly”.

Redwood Plastics offers a sheave design manual available here. While the manual is useful, we don’t want to over-complicate the process either because in most cases a very simple sheave will work that doesn’t require fancy hubs or “webbing”. If you don’t have a design of your own or sample to send us we require only the following information to get started with a quote:

1.) Diameter of the center bore (and confirmation you need a running clearance to spin freely on a shaft).

2.) The overall outer diameter of the sheave.

3.) The type and diameter of the rope or cable being used.

4.) Quantity of sheaves required.

Based off that information we can get a quotation for a simple sheave. Delivery is usually 3-4 weeks and discounts for high volume purchases are often given: so stock up the first time.
