High Quality European Industrial Medium Duty PU Wheel Castors: Red PU on Nylon Rim VS. PU on Aluminium Rim castors

High Quality European Industrial Medium Duty PU Wheel Castors: Red PU on Nylon Rim vs. PU on Aluminium Rim castors

At Rizda Castor, a China PU castor wheel manufacturer, we specialise in producing durable and high-performance PU European industrial caster wheels designed for medium-duty load capacity. In our previous article, we have introduced our PU on aluminium rim wheel castors. Here, we will explore two of our top performing series: Red PU on Nylon Rim wheels and PU on Aluminium Rim wheels, comparing their features, strengths, weaknesses, and ideal applications.

Red PU on Nylon Rim Wheel Castors

Key Features: 
Material: New High-grade polyurethane (PU) injection moulding on nylon rim.
Available Sizes: 3” (80mm), 4” (100mm), 5” (125mm), 6” (160mm), and 8” (200mm) diameters

Bearing Options: 
Roller Bearing for 3"-8" – Ideal for heavier loads with smooth rolling.
Ball Bearing for 3-5 inch – Provides excellent maneuver ability for medium duty applications. Double ball bearing 6-8 inch- Ensures smooth rolling
Load Capacity: 3”-8” around 120-250 kg. Suitable for wheels for trolleys and medium duty industrial use with excellent shock absorption. 

Strengths:

尼龙PU刹车滚针

Lightweight yet durable

Nylon rims reduce overall weight while maintaining strength.

尼龙PU活动单轴

Excellent wear resistance

PU offers superior abrasion resistance.

尼龙PU固定单轴

Chemical & oil resistant

Performs well in harsh environments.

尼龙PU活动滚针

Shock absorbing

Reduces vibration and noise, making them ideal for PU European industrial caster applications.

 

Weaknesses:

Lower heat resistance compared to metal rims (not ideal for high temperature applications).

Lower max load capacity than PU on Aluminium Rim wheels in extreme conditions.

 

Ideal Applications:

1. Factory carts & trolleys 
2. Medical equipment
3. Lightweight material handling
4. Food & beverage industry (non marking PU available)

PU on Aluminium Rim Wheel Castors

Key Features: 
Material: High-performance PU Casting on an aluminium rim.

Available Sizes: 3” (80mm), 4” (100mm), 5” (125mm), 6” (160mm), and 8” (200mm) diameters

Bearing: Double Ball Bearing – Ensures smooth rolling and high load capacity.
Load Capacity: Higher load capability compared to nylon rim wheels.

4寸铝芯PU刹车2

Extremely durable

Aluminium rim provides superior structural integrity.

5寸铝芯PU活动2

Higher load capacity

Ideal for heavier medium duty applications.

6寸铝芯PU固定2

Better heat dissipation

Suitable for warmer environments.

5

Corrosion resistant

Performs well in humid or wet conditions.

Weaknesses: 
Heavier than nylon rims – May add weight to equipment.
Higher cost – Aluminium rims are more expensive than nylon.

 

Ideal Applications:
Heavy duty industrial trolleys

Automotive assembly lines
Machinery movers
Aerospace & logistics equipment 

Comparison Summary: Red PU on Nylon Rim vs. PU on Aluminium Rim Wheels
