Wheel Materials - Choosing the Right Type

The wheel material is the single most important factor when selecting a castor. Each material suits different floor types, load weights and environmental conditions:

  • Polyurethane wheels - the most popular choice for warehouse and factory floors. Floor-friendly, quiet-rolling, wear-resistant and load-bearing. Available in medium-duty and heavy-duty grades. Recommended for most general industrial applications.
  • Super elastic rubber (SER) wheels - the best choice for shock absorption and floor protection. Ideal for trolleys carrying fragile or sensitive loads, or operating on mixed and uneven surfaces.
  • Nylon wheels - lightweight, chemical-resistant and affordable. Suited to light and medium-duty trolleys on smooth, dry floors.
  • Cast iron wheels - extremely durable and heat-resistant to 280°C. Used in foundries, steel mills and high-temperature industrial environments.
  • Pneumatic wheels - inflatable tyre on a steel rim for outdoor and rough-surface applications. Excellent shock absorption for uneven ground.
  • Solid rubber wheels - quieter than nylon, more durable than pneumatic. Good all-round option for mixed indoor and outdoor use.

Castor Configurations Available

All wheel types are available in multiple mounting configurations:

  • Swivel castors - rotate 360° for full manoeuvrability. Used on all four corners of trolleys requiring directional flexibility.
  • Fixed castors - directional only. Typically used on the rear two positions of a trolley for straight-line tracking.
  • Swivel with brake - swivel castor with a locking mechanism to hold the trolley stationary. Required in any application where the trolley must stay in place during loading or unloading.

Series Available

Dreymar's castor range is organised into three main series to suit different load ratings and applications:

  • 22 Series - medium-duty. The most commonly specified series for general warehouse and factory trolleys.
  • 61 Series - heavy-duty with roller bearing. Suited to high-load applications in manufacturing and logistics.
  • TS/XX Series - heavy-duty with double ball bearing. The highest-specification series in the Dreymar range for demanding industrial environments.

Not Sure Which Castor to Choose?

The right castor depends on four factors: load weight, floor type, operating environment and required mobility. If you are replacing castors on an existing trolley, note the existing wheel diameter, plate size and bolt spacing before ordering - these measurements are on the product pages for each series.

For new trolleys and equipment builds, the Dreymar team can assist with castor selection. Explore the full range including 22 Series castors, TS/XX Series castors and scaffold castors.

Industrial Castors and Castor Wheels in South Africa

A castor is a complete mechanical assembly that integrates a wheel inside a mounting housing to enable equipment mobility. While a standalone wheel only rotates on a single fixed axle, a castor features an integrated bracket system that allows for steering, structural attachment, and directional orientation.

The Core Technical Difference: Castors vs Wheels

Understanding the exact structural difference between castors and wheels is critical for safe plant procurement. A wheel is simply the round, rotating component featuring a central bore and integrated bearings. It cannot attach directly to a flat chassis without a separate axle housing.

Conversely, industrial castors enclose the wheel within a robust steel rig (also known as a yoke or fork). This rig is engineered with a mounting plate or stem, converting standard rolling elements into bolt-on mobility systems for heavy machinery, logistics cages, and warehouse work platforms.

Mechanical Configurations: Understanding the Types of Castors

Industrial mobility layouts rely on combining specific types of castors to achieve balance, steering accuracy, and structural tracking control.

Swivel Castors

Engineered with a dual ball-race swivel mechanism in the mounting head, swivel castors rotate a full 360 degrees under load. This design allows operators to maneuver heavy material handling equipment through tightly packed warehouse aisles, changing direction instantly without dragging the structural wheel face.

Fixed (Rigid) Castors

Fixed rigs are structurally locked along a single directional plane. They provide structural directional tracking, ensuring that heavy-duty trolleys travel in straight operational lines over long facility distances without fishtailing or drifting off course.

Braked Castors

Safety regulations across industrial plants demand secure locking compliance. Braked variants integrate a mechanical foot pedal that locks either the wheel rotation alone or provides total lock capabilities, freezing both wheel rotation and the 360-degree swivel matrix simultaneously.

Technical Selection Matrix: Wheel Material Engineering

The wheel material dictates roll resistance, floor preservation, noise dampening, and chemical protection. Selecting the wrong profile can destroy specialized epoxy coatings or freeze up bearings under heavy static loads.

Industrial Material Profiles & Application Alignment

  • Polyurethane Castors: Best for high-capacity corporate warehouses and engineering floors. They offer low rolling resistance and high load capacities while actively protecting concrete surfaces from marring.
  • Nylon Castor Wheels: Best for food processing, pharmaceutical labs, and chemical environments. Solid nylon resists moisture absorption, steam cleaning cycles, and corrosive cleaners, though it runs loudly on rough terrain.
  • Rubber Castors: Best for institutional transport, uneven pavement, and shock absorption. These wheels roll silently over debris, protecting fragile payloads from intense vibrations.
  • Cast Iron Castors: Best for extreme high-temperature environments like bakeries, foundries, and steel manufacturing plants. They deliver virtually zero roll resistance and withstand extreme heat up to 280°C.

Wheel Material vs Floor Type and Performance Matrix

Material Profile Recommended Floor Type Rolling Resistance Floor Protection Temperature Range Primary Industry Use
Polyurethane (PU) Smooth Concrete, Epoxy Very Low Excellent -15°C to 80°C Fulfillment Centres, Automotive Assembly
Nylon (NY) Tiled, Smooth Resin Extremely Low Moderate -10°C to 70°C Abattoirs, Cold Storage, Bakeries
Cast Iron (CI) Steel Plate, Rough Concrete Minimum Low (Marking Risk) -5°C to 280°C Foundries, Brick Kilns, Heavy Engineering
Elastic Rubber (SER) Asphalt, Uneven Concrete Moderate Maximum -20°C to 60°C Waste Management, Outdoor Flight Cases

Load Capacity Classifications and Duty Cycles

Exceeding the rated capacity of your castor wheels creates a high risk of catastrophic failure, flat-spotting, and workplace injury. Industrial configurations are grouped into clear load envelopes based on the thickness of the steel housing, bearing architecture, and axle diameter.
