Kiln bearings operate in some of the most demanding industrial environments, characterized by continuous high temperatures, heavy static and dynamic loads, slow rotational speeds, and constant exposure to dust and vibration. Choosing the right high temperature grease for kiln bearings is essential in cement plants, lime kilns, mineral processing facilities, and metallurgical operations, as proper lubrication plays a decisive role in equipment reliability and production continuity.

Aleman Moil supplies high temperature grease for kiln bearings engineered to support long-term, heavy-duty operation, with a strong focus on bulk supply and stable performance for industrial kiln systems.

Lubrication Challenges in Kiln Bearing Applications

Kiln bearings face a unique combination of stress factors that standard greases are unable to withstand:

• Continuous operating temperatures often exceeding 180–200°C

• Radiant heat from the kiln shell and refractory lining

• Extremely heavy loads and slow rotational movement

• High levels of dust, clinker particles, and mineral debris

• Limited access for frequent relubrication

Under these conditions, conventional greases can oxidize rapidly, harden, or lose oil separation control, leading to increased friction and premature bearing failure.

Aleman Moil high temperature grease is formulated specifically to maintain stability and lubricating performance under these extreme kiln operating conditions.

Typical Kiln Bearing Applications

Aleman Moil grease is suitable for a wide range of kiln-related bearing positions, including:

• Rotary kiln support roller bearings

• Thrust roller and guide roller bearings

• Kiln girth gear auxiliary bearings

• Cooler roller bearings

• Secondary drive and auxiliary equipment bearings

• Preheater and clinker handling system bearings

These bearings often operate continuously for months without shutdown, making lubrication reliability a critical factor.

High Temperature Performance for Continuous Kiln Operation

Aleman Moil high temperature grease for kiln bearings is designed to deliver:

• Continuous temperature capability: 200–220°C

• Short-term peak resistance: up to 280–300°C

• Stable consistency during long-term heat exposure

• Low oil evaporation and controlled bleed

This ensures reliable lubrication even during temperature fluctuations and load changes common in kiln operation.

Optimized for Heavy Loads and Low-Speed Bearings

Kiln bearings typically operate at very low speeds while carrying massive loads. Aleman Moil grease provides:

• Strong oil film strength under boundary lubrication conditions

• Excellent adhesion to bearing surfaces

• Reliable protection against wear and metal contact

• Reduced risk of bearing seizure during startup

These characteristics are essential for protecting large rolling bearings and plain bearings used in rotary kiln systems.

Oxidation Resistance and Clean Bearing Operation

High heat accelerates grease oxidation, leading to deposit formation and hard residue buildup. Aleman Moil high temperature grease features:

• Advanced antioxidant systems

• Reduced carbon residue formation

• Clean operation during extended service intervals

This helps prevent lubrication channel blockage and reduces the risk of bearing overheating.

Resistance to Dust, Debris, and Moisture

Kiln environments are highly contaminated by dust and fine particles. Aleman Moil grease is designed to:

• Maintain sealing properties against dust ingress

• Protect bearings from abrasive contamination

• Resist water washout during cooling or cleaning processes

• Provide corrosion protection in humid conditions

This balanced performance helps maintain bearing integrity in harsh kiln environments.

Extended Relubrication Intervals for Industrial Kilns

Accessing kiln bearings for relubrication is time-consuming and often requires production interruption. Aleman Moil high temperature grease supports:

• Extended relubrication intervals

• Reduced grease consumption

• Lower maintenance labor intensity

• Improved operational safety

For large kiln systems, this directly reduces total maintenance cost over time.

Formulation Options for Different Kiln Zones

Aleman Moil offers multiple grease formulations to match specific kiln bearing requirements:

• Lithium complex systems for balanced heat and load resistance

• Calcium sulfonate complex for superior load and corrosion protection

• Polyurea-based greases for high oxidation resistance

• Specialty non-melting greases for extreme temperature zones

This allows maintenance teams to standardize lubrication across kiln systems while addressing localized operating differences.

Bulk Supply Capability for Kiln Operators

Aleman Moil is structured to support large-volume grease consumption typical of kiln operations.

Supply options include:

• Bulk grease for centralized lubrication systems

• Drums and industrial packaging for maintenance departments

• OEM and private label solutions for long-term projects

• Stable production capacity for annual and multi-year supply contracts

This ensures uninterrupted grease availability for continuous kiln operation.

Consistent Quality and Cost Control

For kiln operators, predictable lubrication performance is essential. Aleman Moil focuses on:

• Strict batch-to-batch quality consistency

• Stable raw material sourcing

• Controlled formulation processes

• Competitive pricing for high-volume procurement

This combination supports long-term cost control without compromising bearing protection.
