Shelf Life and Storage
Timken provides guidelines for the shelf life of grease-lubricated bearings, emphasizing storage conditions to maximize product value. Compliance with European REACH regulations is ensured for lubricants and greases.

Shelf Life and Storage Guidelines:

Do not use products beyond their defined shelf life.
Maintain storage temperatures between 0°C (32°F) and 40°C (104°F) with minimal fluctuations.
Keep relative humidity below 60% and surfaces dry.
Ensure storage areas are free from contaminants and isolated from vibrations.
Follow stricter storage requirements if necessary due to specific conditions or regulations.

Handling and Lubrication:

Most components are shipped with a corrosion-preventive compound, not a lubricant.
Remove this compound before applying specialized grease.
Pre-packed units may require frequent grease replenishment for optimal performance.
Ensure compatibility of different lubricants.
Keep products in packaging until ready for use to prevent contamination.

Warnings and Cautions:

Avoid excessive force during mounting/dismounting.
Follow OEM guidelines for installation and maintenance.

ISO Viscosity System for Industrial Oils

General-Purpose Rust and Oxidation Inhibited Oil
These oils are commonly used in industrial applications to lubricate Timken® bearings where special conditions are not present. They are solvent-refined, high viscosity-index petroleum oils with corrosion and oxidation inhibitors. The viscosity index is a minimum of 80, with a pour point of -10°C (14°F). Viscosity grades range from ISO/ASTM 32 to 220, with higher grades for low-speed/high-temperature applications and lower grades for high-speed/low-temperature applications.

Industrial Extreme-Pressure (EP) Gear Oil
Used for heavily loaded industrial equipment, these oils withstand abnormal shock loads. They are composed of highly refined petroleum oil-based stock with inhibitors and additives, including an EP additive for boundary-lubrication conditions. Viscosity grades range from ISO/ASTM 100 to 460, with higher grades for high-temperature/slow-speed applications and lower grades for low-temperature/high-speed applications.

Grease Consistency and Classification
Grease consistency varies from semi-fluids to solid grades and is measured by penetration number. The NLGI classification ranges from 0 (soft) to 6 (hard). Grease consistency can change with shearing, and its performance is best evaluated through application experience.

Grease Lubrication
Greases are suitable for low-to-moderate speed applications within specific temperature limits. They consist of a base oil, thickening agent, and additives. Common thickeners include lithium, aluminum, and calcium, with synthetic base oils offering higher temperature ranges. Polyurea thickeners are notable for their performance in various applications.

Temperature Considerations
Low temperatures can affect starting torque, requiring greases with low-temperature oils. High temperatures impact grease life, with life halving for every 10°C increase. Greases for high temperatures need thermal stability and oxidation resistance.

Contamination and Grease Selection
Contaminants like abrasive particles and water can damage bearings. Greases with high water resistance, such as calcium and aluminum-complex, are recommended. Grease selection should consider consistency, chemical properties, and environmental conditions.

Timken® Application-Specific Lubricants
Timken offers a range of greases for various applications, including high-temperature, anti-wear, and water-resistant options. Selection should align with equipment specifications and environmental conditions.

Grease Use Guidelines
Proper grease quantity is crucial, with the bearing cavity ideally one-third to one-half full. Excess grease can cause churning and heat generation, while insufficient grease can lead to lubrication starvation.

Grease Lubrication Overview
Grease lubrication is essential for protecting bearing surfaces, especially in environments where sealing is inadequate to prevent contaminants or moisture. During non-operation periods, it is advisable to fill housings with grease for protection, but excess grease should be removed before restarting operations.

Application and Maintenance
Applications using grease lubrication should have a grease fitting and a vent at opposite ends of the housing, with a drain plug at the bottom for purging old grease. Bearings require regular relubrication, though intervals can be difficult to determine without prior experience or consultation with a lubricant supplier.

Grease Types and Properties
Polyurea and lithium-based greases are preferred for general-purpose lubrication due to their water-resistant properties. Excessive grease can cause churning, leading to increased temperatures and breakdown of lubrication. For normal-speed applications, housings should be one-third to one-half full, while low-speed applications may be entirely filled.

Grease Application Methods
Grease is easier to use than oil in industrial applications. It should be packed into bearings to ensure it reaches between rolling elements. Mechanical grease packers may be used in shops for frequent regreasing. The relubrication cycle depends on operating temperature and sealing efficiency.

General-Purpose Industrial Grease
Greases like lithium complex or calcium sulfonate are suitable for most applications. They should be smooth, homogeneous, and contain inhibitors for long-term protection against oxidation and corrosion. The viscosity of the base oil should match the application speed and load requirements.

Grease Compatibility and Application Considerations
Mixing greases can lead to improper lubrication. For high-speed applications, a lighter base oil viscosity is recommended, while lower-speed applications may require a heavier viscosity. Grease fill should be adjusted based on application speed and temperature.
