CASTROL ALPHA SP 150

Why Choose Castrol?

Castrol Alpha SP 150 is a premium mineral-based industrial gear oil formulated with sulphur/phosphorus extreme pressure additives to deliver high levels of protection under demanding operating conditions. Part of the trusted Alpha SP range, this oil is engineered for enclosed gear systems in industrial equipment where load, temperature, and reliability are critical performance factors.

Castrol Alpha SP 150 prevents destructive wear in higher output gear boxes and performs effectively even under cold operating conditions, thanks to its reliable thermal stability and very good viscosity characteristics. Alpha SP 150 extends oil life, reduces the risk of deposit formation in high-temperature environments and meets a number of key industrial standards. As such, it is suitable for a broad range of heavy-duty applications across manufacturing, materials handling, and processing sectors.

This formulation offers outstanding resistance to gear wear and scuffing, and delivers excellent micropitting protection. Castrol Alpha SP 150 also features strong demulsifying properties, enabling quick separation of water and resistance to foaming – both of which are essential for maintaining optimal lubrication in wet or humid environments.

Key performance benefits include:

• Extreme pressure additive system delivers excellent performance for high-load gearboxes.
• High resistance to micro-pitting and gear scuffing.
• Long oil life thanks to oxidative and thermal stability.
• Good water separation and corrosion protection to protect industrial gear boxes.
• Compatible with ferrous and non-ferrous components.
• Low foaming tendency maintains a consistent film strength.

Castrol Alpha SP 150 is a high-quality lubricant that can keep up with the evolving demands of industrial gear systems, and the full range of Alpha SP products can deliver a comprehensive solution to your needs.
