4 Inch Red PP M12*30 Double Ball Bearings With Double Brake Caster - Easy Assembling For Equipment
This caster is designed to provide smooth mobility, precise positioning, and secure locking for equipment, carts, racks, or machinery in industrial, commercial, or workshop environments. The "double brake" system is its standout feature, allowing the user to lock both the wheel rotation and the swivel direction simultaneously.
Breakdown by Feature & Its Functional Purpose
1. 4 Inch Red PP Wheel
Size (4" / 100mm): Offers a good balance between load capacity, rolling ease over small obstacles, and stability.
Material (PP - Polypropylene): A hard, durable plastic. It is non-marking (won't stain floors), corrosion-resistant, easy to clean, and suitable for wet environments. It's quieter than metal but offers less shock absorption than polyurethane. Ideal for smooth concrete, tile, or epoxy floors.
2. M12*30 Threaded Stem
Size: M12 refers to the metric thread diameter (12mm). 30 refers to the length of the threaded portion (30mm).
Assembly: This is the "Easy Assembling" part. You simply drill a correctly sized hole (typically 12.5mm or 1/2"), insert the stem, and secure it from the top with a washer and a hex nut (usually included). This is often faster and more secure than plate-mount casters requiring multiple bolts.
3. Double Ball Bearings (Raceway)
A double row of ball bearings is installed in the kingpin raceway (the swivel mechanism). This distributes the load more evenly than a single ball race.
Benefits: Provides superior swivel performance under heavy loads, reduces "swivel wobble," and ensures the caster turns smoothly even when fully loaded, making equipment easier to maneuver in tight spaces.
4. Double Brake System (Total Lock)
Wheel Brake (Primary Lock): A lever or pedal presses a brake pad directly against the wheel tread, stopping it from rolling.
Swivel Brake (Direction Lock): A separate mechanism (often a smaller lever or by pressing the brake pedal downward) engages a pin or clamp that locks the swivel housing. This prevents the caster from turning or pivoting.
Functional Advantage: When both brakes are engaged, the equipment is fixed in place—it cannot roll and cannot change direction. This is critical for safety on inclines, for precise loading/unloading, or when the equipment is used as a stable workstation.
Summary of Functional Benefits
| Feature | Functional Benefit |
|---|---|
| Double Brake | Maximum Safety & Stability. Locks movement in all directions. |
| Double Ball Bearings | Smooth, Effortless Swiveling under load for superior maneuverability. |
| PP Wheel & Threaded Stem | Easy Assembly & Floor Protection. Simple install and non-marking. |
| 4" Size & Robust Build | High Load Capacity & Durability for industrial use. |
Ideal Applications
Industrial Carts & Trolleys: Used in warehouses, factories, or workshops.
Mobile Workbenches or Racks: Where stability during use is required.
Restaurant or Kitchen Equipment: The non-marking PP wheel is suitable for commercial kitchens.
Audio/Video Equipment Carts: The double brake ensures stable positioning.
Any heavy-duty equipment requiring precise movement and secure locking.
