MOR Conveyor Belting: Protection Against Oil, Grease, and Premature Belt Failure
Protecting Conveyor Belts from Oil Damage
Not all conveyor applications are created equal.
In industries such as food processing, agriculture, recycling, and aggregate handling, materials often contain oils, fats, and grease that can gradually damage standard conveyor belting.
That’s where MOR conveyor belting comes in.
MOR stands for Moderate Oil Resistance, a belt designed to withstand occasional to moderate exposure to oils and greasy materials while maintaining performance and service life.
Why Oil Matters
When oil penetrates standard rubber conveyor belting, it can cause the rubber to swell, soften, and lose its original shape.
Over time, this can lead to:
- Belt distortion
- Tracking problems
- Cover deterioration
- Reduced belt life
- Increased maintenance costs
Even small amounts of oil exposure over long periods can significantly impact belt performance.
Common Applications for MOR Belting
MOR conveyor belting is commonly used in industries where materials may contain fats, oils, or grease but do not require the highest level of oil resistance.
Typical applications include:
Food Processing
Materials such as packaged foods, baked goods, animal feed ingredients, and agricultural byproducts can expose belts to oils and fats during conveying.
Grain & Agriculture
Products including soybeans, oilseed meals, and grain byproducts may contain naturally occurring oils that can affect standard belts over time.
Recycling Operations
Recyclables often arrive contaminated with lubricants, food residue, grease, and other oily materials.
Aggregate and Industrial Processing
Certain mineral products and industrial materials can contain oils or processing residues that accelerate belt wear.
Not All Oil Is the Same
One important consideration often overlooked is that different oils affect rubber differently.
Some applications involve mineral-based oils, while others contain vegetable oils or animal fats. Leading manufacturers, including Fenner Dunlop, have developed specialized compounds to address these different types of oil exposure.
Selecting the appropriate belt compound helps maximize performance and service life.
When MOR Is the Right Choice
MOR belting is typically a great choice when:
- Materials contain occasional oil or grease
- Standard belting has experienced premature wear
- Better belt life is desired without moving to a premium oil-resistant compound
- Operations want to reduce maintenance and replacement frequency
However, severely oily environments may require higher levels of oil-resistant belting beyond a standard MOR specification.
Choosing the Right Belt for the Application
A conveyor belt is an investment, and selecting the correct cover compound can significantly impact long-term operating costs.
At Thaman Rubber Co., we work with customers to evaluate the material being conveyed, operating conditions, and exposure levels to recommend the appropriate belting solution.
Whether you’re handling grain, food products, recyclables, or industrial materials, the right belt can help reduce downtime, improve reliability, and extend service life.
