What type of hydraulic oil is used in the RB-M 45?

The hydraulic oil used in the RB-M 45 is AW-32. This type of oil is specifically formulated for use in hydraulic systems, providing adequate lubrication and ensuring efficient operation under a range of temperatures. The AW (Anti-Wear) classification indicates that this oil contains additives that protect pump and hydraulic component surfaces, enhancing their longevity and overall performance. The viscosity grade of 32 makes it suitable for operating in moderate temperature conditions, which aligns with the expected operational environment of the RB-M 45.

In the context of other options, such as AW-46, ISO-68, and SAE 15W-40, these oils either have different viscosities or are intended for different applications (such as engine oil). AW-46 has a higher viscosity than what is typically recommended for hydraulic systems in this class, potentially affecting performance and efficiency. ISO-68, while it may also be suitable for hydraulic systems, has a different viscosity classification that may not align with the specific requirements of the RB-M 45. SAE 15W-40 is an engine oil and not suitable for hydraulic applications, which require oils specifically designed for that purpose.
