Castrol SPHEEROL EPL 1

Lithium EP Multipurpose Bearing Grease · NLGI 1

Product Description

Castrol Spheerol EPL 1 is a lithium-thickened, extreme-pressure (EP) grease formulated with highly refined mineral base oil, corrosion inhibitors and oxidation inhibitors. It is designed for general-purpose industrial lubrication, particularly where equipment operates under medium to high loads and may be exposed to moisture.

Its NLGI 1 consistency makes it softer and more pumpable than an NLGI 2 grease, making it suitable for selected centralised lubrication systems and applications requiring a softer grease.

Features and Benefits

• Excellent EP and anti-wear protection — helps protect bearings and components under load.

• Good mechanical stability — helps maintain grease consistency during service.

• Good adhesion — supports continuous lubrication and helps reduce lubricant loss.

• Water resistance — helps resist washout in wet operating conditions.

• Corrosion protection — helps protect steel and copper surfaces against corrosion.

• NLGI 1 consistency — provides a softer grease structure than NLGI 2 for suitable applications.

   

  Applications

  • Plain and rolling-element bearings.

  • Industrial machinery and plant-wide lubrication.

  • Chassis lubrication where an NLGI 1 EP grease is specified.

  • Equipment operating under medium to high loads.

  • Lubrication points exposed to damp or wet conditions.

  • Suitable centralised lubrication systems, subject to equipment requirements.

    Storage and Handling

    • Store in the original, tightly closed container.

    • Keep away from excessive heat, moisture and contamination.

    • Use clean grease guns and dispensing equipment.

    • Avoid mixing with other grease types unless compatibility has been confirmed by the lubricant supplier.

    Health and Safety

    Read the current Safety Data Sheet (SDS) before use. Avoid prolonged or repeated skin contact, and clean grease from skin with soap and water. Dispose of used grease and packaging in accordance with local
