1. Nitrile Rubber (NBR) Seals

Nitrile rubber is one of the most commonly used materials for oil seals in rotavators. Renowned for its excellent resistance to petroleum-based oils, it also withstands mechanical wear and tear.

Feature Advantage
Oil Resistance Excellent
Temperature Range -40°C to +100°C
Durability High wear resistance

2. Fluorocarbon (FKM) Seals

Fluorocarbon seals are favored for high-temperature applications. They can withstand extreme temperatures and aggressive chemicals, making them ideal for demanding environments.

Feature Advantage
Temperature Range -20°C to +200°C
Chemical Resistance Superior
Cost Higher than NBR

3. Polyurethane Seals

Polyurethane oil seals are known for their exceptional abrasion resistance. These seals perform well in harsh conditions, often used where resistance to dirt and debris is necessary.

Feature Advantage
Wear Resistance Very high
Flexibility Excellent in cold conditions
Application Heavy-duty use

4. Silicone Oil Seals

Silicone seals are particularly useful for their elasticity and temperature-resistance capabilities. Due to this, they find their applications in environments where conventional seals fail.

Feature Advantage
Temperature Range -60°C to +200°C
Compression Set Low
Durability Long-lasting

5. EPDM (Ethylene Propylene Diene Monomer) Seals

EPDM seals are commonly used for applications involving water and steam. Their excellent weather and ozone resistance make them a reliable choice for outdoor rotavator use.

Feature Advantage
Ozone Resistance Excellent
Temperature Range -40°C to +120°C
Water Resistance Good

6. Viton Seals

Viton is a type of fluoropolymer known for its high resistance to chemicals and high temperatures. It's a go-to option for rotavators operating in extreme conditions.

Feature Advantage
Chemical Resistance Superior
Temperature Range -15°C to +220°C
Durability Long-lasting

7. Metal-Cased Seals

Metal-cased oil seals are used in heavy-duty applications where enhanced strength is necessary. They provide better sealing under high pressure and are durable against heavy impacts.

Feature Advantage
Strength Very high
Application Areas Heavy machinery
Cost Higher than standard seals

Choosing the correct rotavator oil seal can significantly impact the efficiency and functionality of your equipment. Knowing the different types, their characteristics, and the applications they best serve can help you make an informed decision. Always consider aspects such as the working conditions, temperature variations, and chemical exposure before making your choice. Following expert recommendations and insights can further guide you in selecting the ideal oil seal for your rotavator.
