Castrol Optigear Synthetic RO 150 Gear Oil 3HAC042577-001 is a premium synthetic industrial gear oil, specially developed to deliver optimal performance and long-lasting protection for gear systems and gearboxes. This product belongs to Castrol’s high-quality gear lubricant range, a trusted and globally recognized brand in the industrial lubricants sector.
1. Product Description
1.1 Introduction to Castrol Optigear Synthetic RO 150 Gear Oil 3HAC042577-001
Castrol Optigear Synthetic RO 150 Gear Oil is formulated with Castrol’s Microflux Trans (MFT) plastic deformation (PD) additive technology.
MFT PD provides the following advantages:
- Improves performance when operating temperature and load reach a certain activation energy level, by allowing micro-smoothing of surfaces without increasing wear. Smoothed surfaces offer optimal wear resistance and extremely low friction, especially in applications involving extreme pressure, shock loads, vibrations, or low-speed operation.
- Protects equipment from scratches and impacts while maintaining high load-carrying capacity, and may help prevent the progression of micropitting in gears that are already damaged.

1.2 Key Features and Applications
Important features to know about Castrol Optigear Synthetic RO 150 Gear Oil before use:
- Excellent high-pressure absorption and wear protection.
- Reliable bearing lubrication across both high and low temperature ranges.
- Superior load-carrying capability.
- Extended service life, even under challenging operating conditions.
- Reduces friction coefficient and operating temperatures.
- Extends gear life span.
- Mechanical filtration does not deplete additives.
1.3 Product Applications
- Specifically recommended for KUKA robots. Common models include: KR 6 R700 CR, KR 4 R600, KR 6 R1840-2, KR 10 R1420, KR 40 PA, KR 300-2 PA, KR 470-2 PA, KR 120 R2700-2, KR 360, KR 500.
