The weight limits for casters on T-slot frames depend on several factors, including the type and size of the caster, the material of the caster wheel, the number of casters used, and the specific design and configuration of the T-slot frame. Generally, casters are rated by their load capacity, which can range from a few hundred pounds to several thousand pounds per caster.
1. **Caster Type and Size**: Larger casters typically support more weight. For example, a 4-inch caster might support 300-500 pounds, while an 8-inch caster could support 1,000 pounds or more.
2. **Material**: Caster wheels made from materials like polyurethane, rubber, or steel have different load capacities. Steel or high-grade polyurethane wheels usually support heavier loads compared to rubber wheels.
3. **Number of Casters**: The total weight capacity of a T-slot frame is distributed across all casters. For instance, if each caster supports 500 pounds and you use four casters, the total capacity is 2,000 pounds.
4. **Frame Design**: The T-slot frame's design, including the profile size and the way the casters are mounted, affects the overall weight capacity. Heavier-duty profiles and secure mounting increase capacity.
5. **Load Distribution**: Even weight distribution across all casters is crucial. Uneven loads can reduce the effective capacity and lead to caster failure.
6. **Environmental Factors**: Conditions like floor surface, temperature, and exposure to chemicals can impact caster performance and weight limits.
Always consult the manufacturer's specifications for precise weight limits and ensure that the entire system, including the T-slot frame and casters, is designed to handle the intended load safely.
