Non-Marking vs. Non-Marring Caster Wheels: Which is Right for Your Floors?

Non-Marking vs. Non-Marring Caster Wheels: Which is Right for Your Floors?

Caster wheels are designed in a variety of materials to cater to specific needs. A primary concern for many is the potential of wheels leaving marks on floor surfaces.

This has led to the innovation of non-marking and non-marring caster wheels. Among the top choices are soft gray rubber, blue ergonomic rubber caster wheels and polyurethane wheels.
Let’s understand the benefits and applications of these options.

  1. Non-Marking/Non-Marring: Soft gray rubber caster wheels are designed not to leave marks or scuffs on the floor surfaces. This makes them ideal for use on delicate or easily marked flooring, such as hardwood or tile.
  2. Carbon Black Extraction: The extraction of carbon black from the rubber tire is a key factor in their non-marking properties. Carbon black is a common component in many rubber compounds, and its removal helps prevent unsightly marks.
  3. Good Grip: Soft gray rubber wheels typically provide good traction and grip on various floor types, which can be essential for stability and control.

Another popular choice is the polyurethane wheels.


  1. Non-Marking/Non-Marring: Like soft gray rubber wheels, polyurethane wheels are also non-marking and non-marring, making them suitable for protecting floor surfaces from damage.
  2. Resistance to Wear and Tear: Polyurethane is known for its durability and resistance to wear and tear. These wheels are less likely to degrade or break down compared to some other softer rubber options.
  3. Versatility: Polyurethane wheels are versatile and can work well on a wide range of floor surfaces, including both hard and softer materials. They offer consistent performance and longevity.


  1. Non-Marking/Non-Marring: Crafted with precision, these wheels feature blue non-marking injection molded thermoplastic rubber tires. The bonding to a polyolefin center ensures a robust connection, reducing the chances of wear and tear. The choice of materials ensures that the wheels are both durable and gentle on surfaces.
  2. Resilience: Designed to protect the cargo being moved, they offer a cushioned ride without the high costs of natural rubber tires. The cushioned ride they offer is comparable to natural rubber tires but comes without the associated high costs, making them a cost-effective solution.
  3. Applications: Their unique properties make them a favorite in specific industries. They are prominently used in Pharmaceutical Laboratories where precision and care are paramount. Hospitals value them for their quiet operation, ensuring a peaceful environment. The Food Service industry appreciates their resistance to various chemicals and solvents, ensuring hygiene and safety.
  4. Advantages: They provide a softer ride than polyurethane, resist many chemicals and solvents, and are non-marking and quiet. Their shock-absorbing nature and ability to roll over small objects make them a top choice for institutional settings.
