Aluminium Pulley Series
Custom Aluminium Pulley Design
As mentioned, there are 3 types of pulleys, and we manufacture all of them. You can also specify the diameter, width, and many features. Some of the more common sizes include 20-inch, 10-inch, 12-inch, 3-inch, and 8mm aluminum pulleys.
You can request grooves or ribs for your pulleys, which allow for more cable or belt to be wound around the pulley. They could be of the toothed or roller varieties. Some aluminum pulleys have 4 steps, allowing different cables or belt lines to be attached to the same pulley spot. Moreover, you can have crowned or flanged pulleys.
As for parts, you can configure sheaves, side plates, beckets, bearings, and axles.

Aluminum Pulley
It is an axle or shaft wheel that supports motion and distributes tension.
Their simplicity allows them to move heavy things with minimal force.
Using pulleys makes challenging activities easier to manage.
Application of Aluminum Pulley
Pulleys are commonly used in maritime, industrial, and heavy machinery applications.
A pulley is a wheeled device with a rope.
To help raise large objects, pulleys were first designed.
Pulleys are everywhere to help with tasks.
Using several pulleys maximizes mechanical advantage and reduces lifting or pulling force.
Although using more pulleys increases system efficiency owing to friction.
Sailing and fishing ships employ specialized block and tackle systems to raise huge cargo with little force.
There are several belt selections for industry pulleys:
- Timing belt- Has notched teeth to match the corresponding belt’s teeth
- Flat belt- A belt that is completely smooth and free of notches.
- Round Belt- Applies to rotate motion around an axle.
- V-belt- Complements the matching belt with an angled track.
An aluminum pulley is a solid and lightweight metal that has many uses. Aluminum’s appeal is due to its abundance. Also suitable for high-horsepower drives.
Only aluminum can have such horsepower drive systems compared to plastics or nylon.
Aluminum occurs naturally in the continental mantle. Aluminum is abundant, lightweight, flexible, recyclable, and low-maintenance.
- High tensile strength– Its high load capacity and tensile strength make it excellent for heavy materials.
- Excellent heat resistance- Choosing aluminum over other materials is a good example. You should use aluminum timing belts if you work in high-temperature environments. Aluminum strengthens in cold-weather applications.
- Heavy-Duty- Aluminum is solid and consistent dimensions, so you don’t have to worry about your pulley going distorted or twisted.
- Low maintenance- Aluminum resists corrosion naturally. Aluminum is low-maintenance and requires fewer replacements—popular industrial metal due to its low cost and low impact.
Pulleys are simple machinery using a rope and a grooved wheel.
Draw the rope into the wheel’s groove to turn.
Pulleys are used to raise hefty objects.
The load is the thing that a pulley lifts.
Reversing the direction of your lifting force requires tugging down on a rope.
For the same weight, a two-wheel pulley saves force. Only half the weight.
The more wheels and rope you have, the more you can lift.
Simple wheels with loops for rope or heavy chains are called pulleys.
These simple machines allow individuals to move heavier objects with more ease. Using a roller adds to your physical effort.
By tugging down on a rope (looped over the wheel), you can reverse the direction of your lifting power.
For the same weight, a two-wheel pulley saves force. You only lift half the weight. Your Mechanical Advantage is with a two-wheeled pulley.
Leaner weights require less force to lift.
Greater wheels your rope can wrap around, more weight you can raise. A string is coiled around two axes numerous times to form this pulley system.
You increase your ability to lift an object by bringing the lower and upper axes together.
Pulleys are simple machines. The pulley, lever, and inclined plane.
The simplicity of all three sorts of simple machines helps complete work.
Three types of Aluminum Pulley:
Fixed pulley
- These are single-pointed pulleys
- As the name implies, a fixed pulley is attached to a wall or ceiling.
- Because the pulley is constant, the force applied on either side is equal.
- The fixed pulley is required because it changes the direction of the object.
Movable pulley
- A unique pulley unlike a fixed pulley, the pulley machine moves with the load.
- A moving pulley amplifies the user’s force applied to the machine.
- Unlike stationary pulleys, these are generally attached to the thing being pulled.
- It does not affect the direction of the object, but it is helpful because it multiplies force opposing the user. Ideal for bigger loads because less effort is required, but it bears.
Compound pulley
- Pulleys can be moved or fixed. This type of pulley system is ideal for heavier things.
- It multiplies force the most. Due to compound pulleys, these systems need less force from the user and can change load direction.
In situations like this, the guideline is to go with what fits. In the case of precision instruments, simply “fitting” isn’t sufficient.
A rigorous approach is required if you want your project to be exactly where and when you want it.
The pulley’s diameter must be in a ratio: the higher the difference in diameter and thickness ratio, the lower the bending stress, and the longer the belt life.
The ratio is calculated by multiplying the driven component (pump) by the RPM driving component (motor or engine).
The RPM speed controls the pump output flow rate (gallons/min, liters/min).
Poor pump performance results from incorrect RPM. An underperforming pump turns too slowly. However, excessive pump speed might create mechanical issues like valve wear or elastomer failure.
This means that the drive unit (motor, engine, etc.) must be sized correctly relative to the pump.
We’ll assume both with standard electric motors at 1750 RPM and 3400 RPM with conventional gas engines. The drive unit’s rpm must be known to precisely calculate the pulley/sheave size.
It is essential to start with an accurate RPM figure. Reduced equipment lifespan and output flow rates may result. That means more downtime and higher operating costs.
