Castrol Optigear Synth 800/1000, 20L

Castrol Optigear Synthetic 800/1000 is a premium high-viscosity synthetic gear oil based on polyglycol (PAG), specifically developed for the lubrication of slow-speed, heavily loaded gear units operating under severe environmental and thermal conditions. Its outstanding oxidation resistance and high viscosity index ensure exceptional gear protection, extended oil life, and improved mechanical efficiency.

Application:

Recommended for large, low-speed gearboxes operating under high torque loads – typical in heavy industry, mining, pulp and paper, or processing plants. Suitable for lubricating worm, spur, bevel gears and sliding surfaces.

Benefits and advantages:

• Exceptional load-carrying capacity: effective wear protection under extreme pressure conditions.
• Very high viscosity: maintains a strong lubricating film in low-speed and high-load conditions.
• Outstanding oxidation and aging resistance: enables extended oil drain intervals and reduced consumption.
• Excellent compatibility with non-ferrous metals: safe for components made of copper and copper alloys.
• Seal compatibility: suitable for NBR and Viton; not recommended for use with neoprene or butadiene rubbers.
• Reduced energy consumption: low friction coefficient improves gearbox efficiency.

Classification according to standards:

• DIN 51517-3 – exceeds requirements
• ISO 12925-1 – exceeds requirements

Approvals and recommendations:
Not compatible with mineral oils. Compatible with a wide range of sealing materials (NBR, Viton). Previous product name: Tribol™ 800.
