Service Caster Replacement Wheel 16in x 4in - 300 lb Capacity

In this review of the Service Caster Replacement Wheel 16in x 4in, the bottom line is simple: it is a practical, durable replacement for hand trucks, wheelbarrows and dollies that need a reliable pneumatic wheel with a 300 lb capacity per wheel. The reviewer found it straightforward to install thanks to included 5/8 in bearings and spacers, and most useful when the application can accept a 3 in centered hub. If you need a heavy-duty, serviceable pneumatic wheel for manual transport tasks, this wheel delivers consistent performance without surprises.

Key Features

• 16in x 4in pneumatic tire: Provides cushioning and traction on rough surfaces, making it easier to roll loaded carts and wheelbarrows over gravel and yard terrain.
• 300 lb capacity per wheel: Offers a clear load limit suitable for many dolly and wheelbarrow applications, so users can match capacity to the task.
• 5/8 in bearings included: Bearings are supplied to fit a 5/8 in axle or shaft for a direct and secure fit on compatible equipment.
• Spacers for 3 to 6 in hub length: Adapters allow the wheel to work with a range of hub widths, reducing the chance of compatibility issues during installation.
• 3 in centered hub: Centered hub design keeps the wheel aligned for casters and certain dolly types, so buyers can verify clearance before ordering.

Who It's For

This wheel is for homeowners, landscapers, maintenance crews and small businesses that need a replaceable pneumatic wheel for manual transport equipment such as hand trucks, dollies and most 6 cu ft wheelbarrows. It suits tasks where pneumatic cushioning and a 300 lb per-wheel capacity are appropriate.

It is not ideal for applications requiring highway speeds, motorized use, or where axle sizes other than 5/8 in and hub types other than a 3 in centered hub are mandatory. Buyers with offset hubs or unusual axle dimensions should check fitment before purchase or seek a different hub configuration.

Pros & Cons

• 300 lb capacity per wheel provides a predictable load rating for planning tasks.

Cons

• Centered 3 in hub requires enough clearance and may not fit equipment using offset hubs.
