Hydraulic oil R&O for circulating lubrication systems

Hydraulic oil R&O is an industrial lubricating oil with rust and oxidation protection, designed for hydraulic and circulating lubrication systems that do not require a high level of anti-wear properties. Its viscosity-temperature characteristics help maintain lubricating, cooling, and sealing capability under varying operating temperatures and system conditions.

The product provides oxidation stability, rust protection, foam suppression, air release, demulsibility, and filterability. Typical applications include hydraulic reservoirs of machine tool spindles, low-load hydraulic equipment, enclosed gearboxes, and industrial circulating lubrication systems.

MOSINTER GROUP coordinates production resources through invested manufacturing facilities, and Ningbo MOS Chemical Co., Ltd. supports international buyers with wholesale supply, bulk procurement, OEM and private label coordination, export documentation, and product specification alignment.

  • Formulation with corrosion and oxidation inhibitors
  • Available in viscosity grades from ISO VG 15 to ISO VG 150
  • Good foaming and air release properties
  • Water Separation and Filtration Characteristics
  • Support for Wholesale and Bulk Purchases
  • OEM, Private Label, and Export Cooperation
