Grease Suppliers UAE: Complete Buying Guide
Everything mining, construction, and manufacturing operators need to know about selecting industrial grease and choosing the right supplier in the UAE
Industrial grease is the silent protector of every bearing, pivot point, and sliding surface in your equipment. Choosing the wrong grease or an unreliable supplier leads to bearing failures, seized components, and costly downtime. This guide helps UAE procurement managers and maintenance engineers make informed decisions about industrial grease selection and supplier evaluation.
At DANA Lubes, we manufacture and supply a complete range of industrial greases from our UAE facility, serving mining operations, construction companies, and manufacturing plants across the Gulf region.
Understanding NLGI Grease Grades
The National Lubricating Grease Institute (NLGI) classifies greases by consistency, similar to how viscosity classifies oils. Understanding NLGI grades is essential for selecting the right grease for your application.
| NLGI Grade | Consistency | Common Applications |
|---|---|---|
| NLGI 000 | Very fluid | Centralized systems, extreme cold |
| NLGI 00 | Fluid | Centralized lubrication systems |
| NLGI 0 | Semi-fluid | Centralized systems, cold climates |
| NLGI 1 | Soft | Centralized systems, cold temperatures, low-load bearings |
| NLGI 2 | General purpose | Most automotive and industrial bearings, chassis, wheel bearings |
| NLGI 3 | Medium | High-temperature applications, heavy loads, water exposure |
| NLGI 4-6 | Hard | Specialized applications, slow-speed heavy loads |
Types of Industrial Grease: Thickener Technology
The thickener is the skeleton that holds oil in place. Different thickeners offer different performance characteristics. Here are the most common types available from UAE grease suppliers:
Lithium Complex Grease
The most widely used industrial grease. Offers excellent all-around performance with good water resistance, mechanical stability, and a dropping point around 260C. Suitable for temperatures from -20C to +150C. Compatible with most other lithium greases.
Calcium Sulfonate Grease
Premium performance grease with exceptional water resistance, extreme pressure protection, and dropping points above 300C. Inherently EP without additives. Ideal for wet environments, heavy shock loads, and applications where water washout is a concern. Excellent for mining and marine applications.
Polyurea Grease
Long-life grease with excellent high-temperature stability and oxidation resistance. Dropping point above 280C. Commonly used in sealed-for-life bearings, electric motors, and high-temperature applications. Not suitable for high-load applications.
Aluminum Complex Grease
Excellent water resistance and pumpability. Good for centralized lubrication systems and applications requiring high water resistance. Dropping point around 250C. Often used in steel mills and paper machines.
Bentonite (Clay) Grease
Non-melting grease with no dropping point. Excellent high-temperature stability. Used in applications where grease must not melt and run out. Limited low-temperature performance and poor compatibility with other greases.
EP2 Grease: The Workhorse of Mining and Construction
EP2 (Extreme Pressure, NLGI 2) grease is the most commonly specified grease in mining and construction equipment. It contains extreme pressure additives that form protective layers under heavy loads, preventing metal-to-metal contact.
When to Use EP2 Grease
- Heavy equipment pivot points (boom joints, bucket links, blade circles)
- Wheel bearings on trucks and loaders
- Universal joints and drive shafts
- Track roller and carrier rollers
- Slewing rings and swing circles
EP2 Grease Specifications to Look For
- Timken OK Load minimum 40 lbs (ASTM D2509)
- Four-ball weld load minimum 315 kg (ASTM D2596)
- Water washout less than 10% (ASTM D1264)
- Dropping point minimum 260C (ASTM D2265)
How to Choose the Right Grease for Your Application
Step 1: Identify Operating Temperature Range
For UAE applications, consider both ambient temperature (up to 50C in summer) and equipment operating temperature. Standard lithium complex grease handles up to 150C. For higher temperatures, specify polyurea or calcium sulfonate.
Step 2: Assess Load Conditions
Light to moderate loads can use standard NLGI 2 grease. Heavy shock loads or high-pressure contacts require EP additives. For extremely heavy loads, calcium sulfonate grease provides superior protection.
Step 3: Evaluate Water Exposure
If bearings are exposed to water spray, immersion, or high humidity, choose calcium sulfonate or aluminum complex grease. These offer superior water resistance and resist washout.
Step 4: Consider Re-greasing Intervals
If manual re-greasing is difficult or infrequent, specify long-life synthetic grease (polyurea or PAO-based). For centralized lubrication systems, ensure the grease has good pumpability at system operating temperature.
Step 5: Check Compatibility
Never mix incompatible greases. Lithium complex is generally compatible with other lithium greases. Mixing lithium with calcium sulfonate, polyurea, or bentonite can cause softening and leakage. Always flush the system when switching grease types.
What to Look for in UAE Grease Suppliers
Not all grease suppliers offer the same level of service and support. Here are the key factors to evaluate when choosing a grease supplier in the UAE:
Manufacturing Location
UAE-based manufacturers like DANA Lubes offer shorter lead times, lower shipping costs, and better availability compared to importers. Local manufacturing also means products are formulated for regional climate conditions.
Product Range and Availability
Choose a supplier with a comprehensive range of NLGI grades and thickener types. They should stock common products for immediate delivery and offer custom formulations for specialized applications.
Technical Support
The best suppliers offer lubrication surveys, grease selection assistance, and on-site technical support. They should help you optimize re-greasing intervals and troubleshoot lubrication problems.
Quality Certifications
Look for ISO 9001:2015 certification and products that meet international standards (NLGI, ASTM, DIN). Request certificates of analysis for each batch.
Bulk Packaging Options
For large operations, suppliers should offer bulk packaging (180 kg drums, 900 kg IBC containers, or tanker delivery) to reduce packaging waste and handling costs.
Common Grease Mistakes in UAE Operations
- Over-greasing bearings — Causes churning, overheating, and seal damage. Fill only 30-40% of the housing cavity.
- Mixing incompatible greases — Causes softening, oil separation, and lubrication failure. Always identify the existing grease before topping up.
- Using automotive grease in industrial applications — Automotive chassis grease lacks the EP additives and dropping point required for industrial equipment.
- Ignoring re-greasing intervals — Both over-greasing and under-greasing cause failures. Follow OEM recommendations or conduct grease analysis.
- Storing grease improperly — Grease stored in direct sunlight or extreme heat degrades. Store indoors between 10C and 30C.

Frequently Asked Questions
What are the best grease suppliers in UAE?
The best grease suppliers in UAE offer NLGI-certified products, bulk delivery capabilities, and technical support. DANA Lubes is a leading UAE-based manufacturer supplying lithium complex, calcium sulfonate, and EP2 greases for mining, construction, and industrial applications across the Gulf.
What NLGI grade grease should I use?
NLGI 2 is the most common grade for general-purpose applications. NLGI 1 is used for centralized lubrication systems and cold temperatures. NLGI 3 is used for high-temperature applications and heavy loads. Mining and construction equipment typically requires NLGI 2 EP grease.
What is the difference between lithium and calcium sulfonate grease?
Lithium complex grease offers good all-around performance with dropping point around 260C. Calcium sulfonate grease provides superior water resistance, extreme pressure protection, and dropping points above 300C. Calcium sulfonate is preferred for wet environments and heavy shock loads.
How much grease should I apply to bearings?
For most bearings, fill 30-40% of the housing cavity. Over-greasing causes churning and overheating. For high-speed bearings above 3,000 RPM, fill only 20-30%. The exact amount depends on bearing type, speed, and operating temperature.
