Window regulator pulleys

Types of Window Regulator Pulleys

A window regulator pulley is a small wheel that is often found in the window regulator assembly. The pulley is used to help the window lift or lower smoothly without any hitches. The window regulator pulley is a vital component of the window regulator. However, it is not a standalone part and is often sold together with the window regulator in an assembly. The window regulator pulley comes in different types, which include:

• Plastic window regulator pulley: This is one of the most common types of window regulator pulleys. It is made from a durable plastic material. As earlier mentioned, the window regulator pulley is not a standalone part. It is often found in a worn-out window regulator assembly. In this case, the window regulator pulley plastic can wear out easily. More so, they can become damaged or cracked when too much physical pressure is applied to the vehicle window. This makes them a bit affordable. They are also lightweight and quiet when the window is being operated. The only downside to plastic pulleys is that they do not have a long lifespan.
• Steel window regulator pulley: Steel window regulator pulleys are found in premium or high-end vehicles. Unlike plastic pulleys that are made from plastic materials, the steel window regulator pulley is made from durable steel material. This makes them long-lasting. The steel window regulator pulley can withstand a lot of physical pressure or weight on the vehicle window. They also come in handy in a worn-out or damaged window regulator assembly. Steel pulleys are robust and can lift windows more quickly than their plastic counterparts. The only downside to steel window regulator pulleys is that they are noisy. They also come with a heavy price tag, which might be a con for many vehicle owners.
• Brass window regulator pulley: The brass window regulator is by far the most durable among the other two types of window regulator pulleys. It is made from brass material, which is a combination of steel and zinc. The brass window regulator pulley is quite versatile and can be used in a variety of window regulator systems. The brass window regulator pulley is quiet and smooth when the window is being operated. It is also a good choice when replacing worn-out or damaged pulleys in the window regulator system. The only downside to the brass window regulator pulley is that it is quite expensive.

Specification & Maintenance of Window Regulator Pulleys
