Mechanics use wheel balancing machines or wheel balancers to ensure the weight of the wheels in a vehicle is evenly balanced. This is essential to ensure smooth rotation under different road conditions. In case of imbalances, a mechanic or a technician adjusts the wheel weight so that it is equally distributed.

Working with wheel balancers

Modern-day wheel balancers are not just confined to checking the weight, but they’re also used to determine the specific reason for imbalance and the amount of weight that needs to be added. This helps the mechanic solve any problems in the entire assembly that might lead to tire vibrations or other issues.

There are three different types of wheel balancers:

Static balancer

  • Dynamic balancers: They are large power units that are usually owned by high-volume garages and mechanic shops. They offer precision and high-quality work; hence are typically expensive and handled by professionals in the field. It consists of a motorized spindle, and when the wheel equipment is placed on them, they stimulate spinning forces similar to when attached to a vehicle. They generally cover tires that are over or equal to 50 inches.
  • Static balancers: These balancing machines are slightly less expensive and are generally designed for low-duty vehicles. They are excellent machines intended to check the weight and balance of a wheel without spinning it. It consists of a static, non-rotating spindle on which the wheel assembly is mounted. The wheel’s balance is checked through sensors mounted on the spindle. Although these machines’ precision is less than dynamic balancers, they are handy and occupy less space.
  • Bubble balancers: These are static balancers that work similarly to static ones. When the wheel assembly is placed on a non-rotating spindle, it checks for the angle of imbalance by a center bubble, shown in an oil-filled glass gauge. These balancers weigh less than 15 pounds and are recommended for small-sized garages.

Safety tips for wheel balancers


Although all types of wheel balancers are safe to use, some precautions are necessary, which are mentioned below:

  • Checking the equipment: It is essential to check the balancer regularly and keep tabs on their working condition, as suggested by the manufacturer.
  • Protective gear: It is essential to wear protective equipment while using any machinery. This includes safety goggles, gloves, steel-toe shoes, ear protection, tight clothes, etc.
  • Please read the manual: It is essential to read the technical manual that comes along with the kit before using the equipment. It might even contain safety tips and preventive measures.
  • Please pay attention: While working with heavy machinery, it is essential to pay attention, especially while clamping the wheel to the spindle. Also, it is necessary to make sure nothing comes in the way when the machine is on.
  • No shortcuts: Even if the checking procedure is lengthy, it is imperative to stick to it without any shortcuts as it might cause damage to the wheel and the machinery.
