Key Features and Specifications
A 100mm (4-inch) industrial caster with a double brake system and polypropylene (PP) wheel typically includes the following specifications based on industry standards :
| Feature | Typical Specification | Description |
|---|---|---|
| Wheel Diameter | 100mm (4 inches) | Standard size for medium-duty industrial equipment requiring moderate ground clearance and maneuverability. |
| Wheel Material | Polypropylene (PP) | Rigid, lightweight thermoplastic with good chemical resistance. The orange color provides high visibility for safety compliance. |
| Bearing Type | Double Ball Bearing (common) | Ensures smooth rolling with minimal effort, even under heavy loads . |
| Brake Type | Double Brake (Total Lock) | Simultaneously locks both wheel rotation and swivel action for complete equipment stability . |
| Mounting Type | Flat Top Plate | Standard bolt-on configuration with hole patterns such as 80×60mm, 76×67mm, or 76.2×101.6mm . |
Functional Benefits for Industrial Equipment
The 100mm orange PP double brake caster offers several practical advantages in industrial settings:
-
Secure Positioning with Double Brake: The primary benefit is safety and stability. The double brake mechanism (also called total stop brake) locks both the wheel rotation and the swivel movement simultaneously . This ensures your equipment stays perfectly stationary during operation, loading, or when parked on slightly inclined surfaces.
-
Smooth Maneuverability: Double ball bearing raceways allow for effortless directional changes and smooth rolling, reducing operator fatigue when moving heavy machinery or equipment carts in workshops and factories .
-
Floor-Friendly Operation: Polypropylene wheels are hard enough for durability yet non-marking, so they won't leave dark skid marks on clean factory floors, epoxy surfaces, or warehouse concrete .
-
Chemical & Moisture Resistance: PP material resists many industrial chemicals, oils, and moisture, ensuring reliable performance in environments where spills may occur .
-
Easy Push Effort: The combination of low-friction PP material and quality bearings means equipment starts moving with minimal force, improving workplace efficiency .
-
High-Visibility Safety: The bright orange color serves as a visual safety indicator, making equipment boundaries more noticeable and helping to prevent trip hazards in busy industrial environments.
Ideal Applications
This caster configuration is well-suited for a variety of industrial and commercial settings:
-
Industrial Machinery: Perfect for movable machine bases, assembly line fixtures, and manufacturing equipment that needs to be positioned precisely and then locked securely during operation .
-
Material Handling Equipment: Ideal for transport carts, dollies, and storage racks in warehouses and distribution centers where secure parking is required .
-
Tool and Maintenance Carts: Suitable for heavy-duty mechanic's toolboxes and service carts that need to be positioned under equipment and locked to prevent rolling during use.
-
Workshop Equipment: Great for workbenches, welding tables, and fabrication equipment that requires mobility for reconfiguration but stability during work .
-
Industrial Storage: Useful for heavy-duty shelving units and cabinet systems that need to be moved for cleaning or reconfiguration but must remain stationary during normal use.
-
Manufacturing Facilities: Well-suited for production line support equipment, parts bins, and assembly stations where periodic repositioning is needed .
