ML538 - 5-Inch Rigid Blue Rubber Replacement Caster Wheel

Reliable Mobility for Industrial Environments

The ML538 Caster Rigid Blue Rubber 5" is a high-quality replacement component designed to restore or enhance the mobility of your industrial equipment. In the world of gas distribution and welding supply, the reliability of transport equipment—such as cylinder carts, welding trolleys, and material dollies—is paramount. A failed caster can halt production or create safety hazards when moving heavy compressed gas cylinders. This 5-inch rigid caster is engineered to provide a stable, durable solution for these demanding applications.

Constructed with a robust steel housing, the caster features a zinc-plated finish that offers excellent resistance to rust and corrosion, a common issue in workshops where humidity and chemical exposure vary. The "rigid" or fixed design means this caster does not swivel, making it the ideal choice for the rear wheels of a cart, providing directional stability and ensuring the equipment tracks in a straight line during transport. This is particularly important for heavy loads where steering control is critical.

Optimized Wheel Material

The standout feature of this component is its Blue Rubber wheel material. Unlike hard plastic or phenolic wheels that can be noisy and transmit vibration, blue rubber offers a cushioned ride. This elasticity allows the wheel to roll smoothly over small obstacles, cracks in the concrete, or electrical cords without getting stuck or causing excessive jarring to the equipment on board. Furthermore, blue rubber is specifically formulated to be non-marking, ensuring that it leaves no unsightly black streaks on epoxy-coated or polished concrete floors, maintaining the professional appearance of your facility.

Whether you are repairing an existing fleet of cylinder carts or building a custom fabrication trolley, the ML538 provides the load-bearing capacity and smooth operation required for professional use. Its solid tire construction eliminates the maintenance headaches associated with pneumatic tires—you will never have to worry about a flat tire stopping your work again.
