Nitrile Rubber Wheels

Nitrile rubber wheels are industrial wheels mainly made of nitrile rubber (NBR). Nitrile rubber is a synthetic rubber made by copolymerizing butadiene and acrylonitrile, and its performance (especially oil resistance) depends on the content of acrylonitrile (ACN). The higher the content, the better the oil resistance, but the low-temperature elasticity will slightly decrease. Simply put, it is a rubber wheel specially designed to resist oil and fuel.

Excellent oil resistance and flame resistance:
This is the fundamental reason why it is widely used. It has strong resistance to mineral oil, vegetable oil, fatty hydrocarbons, gasoline, and diesel, and will not swell, soften, or degrade like ordinary rubber.

Good wear resistance:
In oily environments, it exhibits excellent wear resistance and long service life.

Good heat resistance:
It can usually work continuously at temperatures ranging from 100 ° C to 120 ° C, with higher short-term heat resistance than many general-purpose rubbers.

Higher mechanical strength:
Has good tear and tensile strength, and can withstand certain heavy loads and impacts.

Good airtightness:
The dense molecular structure makes it very suitable for manufacturing components that require maintaining air pressure, such as tire inner tubes.

General weather resistance: not resistant to ozone, ultraviolet radiation, and weather aging. Long term exposure to outdoor sunlight and rain can easily lead to cracking. Not suitable as the first choice for outdoor wheels.

Poor low-temperature performance: it will harden and reduce elasticity at low temperatures, making it unsuitable for use in extremely cold environments.

Poor resistance to polar solvents: not resistant to polar solvents such as ketones, esters, chlorinated hydrocarbons, etc.

Solid nitrile rubber wheels:

• Structure: The entire wheel is made of solid nitrile rubber.
• Advantages: Never tire blowout, maintenance free, strong load-bearing capacity.
• Application: Industrial handcarts, forklifts, oil depot equipment, factory workshop handling equipment.

Nitrile rubber coated wheels:

• Structure: A wheel core made of metal (usually steel or cast iron) or high-strength plastic (such as nylon) as the skeleton, wrapped with a layer of nitrile rubber on the outside.
• Advantages: Combining the ultra-high load-bearing strength of the metal wheel core with the oil resistance, toughening, and ground protection properties of the nitrile rubber surface. It is an ideal choice for heavy-duty situations.
• Application: Drive wheels for heavy-duty forklifts, AGV small wheels, and track wheels for heavy-duty platforms.

Micro foamed nitrile rubber wheel:

• Structure: The rubber contains tiny bubbles inside.
• Advantages: lighter weight, better shock absorption and ground protection.
• Application: Medium sized load-bearing equipment with requirements for weight and shock absorption.

Features:

• High load-bearing capacity - designed for continuous use under heavy loads
• Low noise operation - very suitable for indoor and noise sensitive environments
• Non marking rubber or PU pedals - protect the floor and provide excellent grip
• Customizable cores - steel core, aluminum core or cast iron core can meet various needs
• Precise balance - smooth rotation ensures stability and accuracy of motion
• Rubber to metal or PU to metal bonding - Advanced bonding technology ensures long lifespan and durability

Controlling quality during the wheel production process is crucial to ensure safety, durability, and accuracy, especially since these wheels operate in automated systems with minimal errors. Here is a breakdown of how to control quality at each stage of wheel manufacturing:

1. Raw material inspection
2. Pre bonding surface treatment
3. Forming or casting process
4. Size and appearance inspection
5. Hardness and load testing
6. Final assembly and functional testing
7. Traceability and documentation
