Product Description
A 90mm pulley is a pulley with a diameter of 90 millimeters. It is a type of wheel that has a groove around its circumference to accommodate a rope or cable. Pulleys are used to change the direction or magnitude of a force.
When choosing a 90mm pulley, it is important to consider the following factors:
- Material: Pulleys are typically made of metal or plastic. Metal pulleys are more durable, but they are also more expensive. Plastic pulleys are less expensive, but they are not as durable.
- Bearing type: Pulleys can have either ball bearings or sleeve bearings. Ball bearings are more efficient and smoother running, but they are also more expensive. Sleeve bearings are less expensive, but they are not as efficient or smooth running.
- Load capacity: The load capacity of a pulley is the maximum amount of weight that it can safely support. It is important to choose a pulley with a load capacity that is greater than the weight of the load that will be suspended from it.
If you are unsure which type of 90mm pulley is right for your application, it is a good idea to consult with a professional.
