Anytime you need to connect multiple shaft systems with one another, a timing pulley is required.
The construction of the timing pulley that you utilize within your shaft systems is important. Construction impacts the lifespan and efficiency of a timing pulley. One of the construction elements that you must pay attention to when selecting a timing pulley is the material the pulley is made from.
Modern pulleys are typically made from either nylon or aluminum. Understanding the benefits and drawbacks of each material will help you better determine which is best suited to meet your needs.
Nylon Timing Pulleys
More and more timing pulley systems are being made from nylon thanks to advancements in plastics technology.
Nylon is a lightweight, yet very strong material. This allows a nylon timing pulley to bear a significant amount of force without adding a lot of weight to your shaft systems.
Nylon is also a very affordable material to produce. Timing pulleys that are constructed using nylon tend to be more affordable than their aluminum counterparts.
Nylon timing pulleys are only appropriate for use in shaft systems that maintain a relatively stable temperature. Exposure to high temperatures can cause a nylon timing pulley to melt, which could damage multiple components within a shaft system.
Aluminum Timing Pulleys
Aluminum has an incredibly high tensile strength. This tensile strength allows an aluminum timing pulley to operate efficiently within shaft systems that exert a high level of horsepower. Too much horsepower could create tears in a nylon timing pulley.
Aluminum is naturally resistant to corrosion. This property makes an aluminum timing pulley a great choice for shaft systems that may be exposed to moisture or other contaminants over time. The aluminum will not break down, and the timing pulley will retain its integrity.
High-temperature shaft systems must be fitted with aluminum timing pulleys. The melting point of nylon is lower than the melting point of aluminum. This means that aluminum timing pulleys can withstand prolonged exposure to high temperatures without sustaining any serious damage.
Both nylon and aluminum timing pulleys play important roles within modern shaft systems. To ensure you are selecting the right material for your shaft systems, you must identify the operating conditions the timing pulley must endure.
Temperature, exposure to the elements, and tensile strength requirements must all be evaluated to determine whether nylon or aluminum is the right material for your timing pulleys.
I was surprised how many decisions needed to be made when purchasing a water heater. You need to decide whether you want a traditional tank heater or a tankless water heater. You need to determine what sized water heater you need based on the size of your bathtubs, water appliances, how long you like to shower and the number of people living in your home. And you need to determine what brand of water heater makes the most sense for your budget and needs. I was floored with all the decisions I needed to make and being uneducated made me worry about picking the wrong water heater. I started this website because I want people who are looking to buy a water heater to go into a store educated on what water heater is best for them. I hope you find my site beneficial.
