Description
Castrol High Temperature Grease – Multipurpose High-Temperature Grease
Description: Castrol High Temperature Grease is a high-performance, multipurpose lithium complex grease developed using an optimized combination of high-quality mineral oil, proprietary thickener technology, and a specially selected additive system. This enables reliable performance across a wide range of temperatures while being exposed to various operational loads, speeds, and environmental conditions.
Application: Castrol High Temperature Grease is intended for use in a wide range of plain and rolling element bearings within both the automotive and industrial markets. It specifically targets applications where upper operating temperatures are likely to exceed the limits of conventional lithium-thickened greases. The excellent thermal and mechanical stability of Castrol High Temperature Grease makes it particularly suitable for automotive bearing applications where rotational speeds may be higher, or prolonged heavy braking may generate higher than normal hub temperatures. Specific examples include cars fitted with disc brakes or commercial vehicles such as trucks or buses. Castrol High Temperature Grease also offers good resistance to water and corrosion, as well as very good load-carrying performance, making it suitable for general vehicle chassis lubrication or bearings on off-road construction vehicles where greater extremes of pressure may be prevalent.
Advantages:
- Excellent thermal and mechanical stability: Ensures prolonged product integrity across a wider operating temperature range, allowing extended relubrication intervals and reduced maintenance.
- Good extreme pressure and anti-wear properties: Prolongs component life.
- Good water resistance: Provides enhanced protection in applications with high potential for exposure and contamination.
- Good corrosion protection.
- Excellent multipurpose potential: Enables a reduction in product inventory.
