1. Nylon Wheel
- Description: Nylon wheels are a type of wheel made from high-quality nylon, a durable thermoplastic material. They are widely used in trolleys and other construction machinery accessories due to their lightweight, high load-bearing capacity, and resistance to wear and tear. Nylon wheels are typically smooth and are known for their ability to handle a wide range of temperatures, chemicals, and outdoor conditions.
- Uses in Construction Machinery: These wheels are commonly used in trolleys, carts, and mobile equipment in construction sites. They provide smooth movement over flat surfaces and are used to carry tools, materials, or small construction equipment. Nylon wheels are also favored for their low rolling resistance and ability to support heavy loads while remaining corrosion-resistant.
2. Pneumatic Wheel
- Description: Pneumatic wheels are wheels that use air-filled tires to provide cushioning and shock absorption. These wheels consist of a rubber tire filled with air, mounted on a rim. The air in the tire helps absorb impact, reduce vibration, and provide a smooth ride over rough terrain, making pneumatic wheels ideal for outdoor and construction environments.
- Uses in Construction Machinery: Pneumatic wheels are primarily used on trolleys, wheelbarrows, and construction equipment that need to travel over uneven or rough terrain. They are commonly used on heavy-duty carts, trailers, and equipment that are moved around construction sites. The air-filled tires are excellent for reducing stress on equipment and providing better mobility on gravel, dirt, or unpaved surfaces.
3. Bearing 6204
- Description: The 6204 bearing is a standard deep groove ball bearing commonly used in various machinery, including construction equipment and trolleys. It consists of an inner ring, an outer ring, a set of steel balls, and a cage that separates and holds the balls in place. The 6204 bearing is designed to handle radial loads and moderate axial loads, making it suitable for high-speed applications.
- Uses in Construction Machinery: Bearing 6204 is commonly used in wheels (including both nylon and pneumatic wheels) and various other rotating components on construction machinery. It ensures smooth rotation by minimizing friction between moving parts, thus prolonging the life of the machinery. Bearings like the 6204 are often found in wheel hubs, axles, motors, and gear systems in equipment such as cranes, trolleys, loaders, and conveyors, where precision and durability are crucial.

Trolley Accessories- Specification
1. Nylon Wheel
- Material: High-quality nylon (often reinforced with glass fiber for added strength)
- Diameter: Common sizes range from 2 inches to 12 inches, but larger wheels are available depending on the load requirements.
- Load Capacity: Typically ranges from 50 kg to 500 kg (110 lbs to 1100 lbs), depending on wheel size and material reinforcement.
- Bore Size: The diameter of the hole in the center of the wheel, typically ranging from 1/2 inch to 2 inches, depending on the axle size.
- Wheel Type: Plain or with a bearing (the latter allows smoother rotation and higher load capacity).
- Temperature Range: Typically can handle temperatures from -20°C to 80°C (-4°F to 176°F), with some models capable of withstanding higher or lower temperatures.
- Resistance: Resistant to chemicals, oils, water, and UV degradation, making them ideal for construction environments.
- Surface Type: Smooth or textured, depending on the requirement for grip or ease of movement.
2. Pneumatic Wheel
- Material: Rubber tire with air-filled inner tube, mounted on a rim made of steel or plastic.
- Diameter: Common sizes range from 6 inches to 16 inches, but sizes can go up to 24 inches or more for heavy-duty equipment.
- Load Capacity: Typically ranges from 100 kg to 1000 kg (220 lbs to 2200 lbs) depending on the size of the wheel and tire.
- Tire Pressure: Typically ranges from 30 psi to 50 psi, depending on the weight and load distribution of the machinery.
- Bore Size: Usually ranges from 1/2 inch to 2 inches, with variations depending on the axle size.
- Wheel Type: Single or dual tires for different load distribution. Some wheels have an offset hub for better stability.
- Surface Type: Knobby or smooth tread depending on the requirement for better traction or smoother movement.
- Shock Absorption: Air-filled tires provide natural shock absorption, improving ride quality on uneven or rough terrain.
- Temperature Range: Typically can operate in temperatures from -30°C to 70°C (-22°F to 158°F).
