Castrol Tribol 943 AW-46  Castrol Tribol 943 AW Hydraulic & Circulating Oil Description Castrol Tribol™ 943 AW (anti-wear) hydraulic ａnd circulating oils were developed to meet the demands of the most severe hydraulic applications. These high performance, ashless (zinc-free), multi-service oils can extend service life for uninterrupted machine availability ａnd production. The following performance characteristics are emphasized: Oxidation stability to significantly extend safe oil service life ａnd to protect tight machine clearance from varnish or deposits. Anti-wear protection to maintain crucial tolerance characteristics of advanced hydraulic systems ａnd to protect gears ａnd bearings in circulating systems. Corrosion resistance to give protection, exceeding normal industry standards, against damage from condensed atmospheric moisture. Applications Hydraulics - designed for the most sophisticated hydraulic operations, robots, ａnd other NC machines, Tribol 943 AW oils may be used in any industrial, marine, or mobile applications. Circulating systems - outstanding anti-wear properties make Tribol 943 AW oils ideal for multicomponent systems including anti-friction ａnd journal bearings ａnd all types of gears except where manufacturers specify AGMA "EP" or “Compounded” gear oils. Compressors – Tribol 943 AW 32 ａnd Tribol 943 AW 46 in centrifugal ａnd flooded screw compressors can significantly extend oil service life compared with conventional petroleum compressor oils ａnd ATF fluids. In fact, drain intervals approach the range of some synthetic fluids. Tribol 943 AW oils may also be used in reciprocating compressors if temperatures are not high ａnd units are not prone to valve deposits. The wide array of Tribol 943 AW applications provides excellent opportunity to consolidate inventory. The Tribol 943 AW range is fully compatible with the elastomer materials commonly used for static ａnd dynamic seals, such as nitrile, silicone ａnd fluorinated (e.g. Viton) polymers. Tribol 943 AW is classified as follows: DIN 51502 classification - HLP ISO 6743/4 - Hydraulic Oils Type HM Tribol 943 AW grades meet the requirements (for appropriate viscosity grade) of: DIN 51524 Part 2 Cincinnati Lamb (Milacron) P 68-69-70 Denison (Parker Hannafin) HF-0 US Steel 126 & 127 Eaton (formerly Vickers) 35VQ 25, I-286-S & M-2950-S Bosch Rexroth RE90220 Lee Norse 100-1 Jeffrey No. 87 Ford M-6C32 B.F. Goodrich 0152 Advantages  The base oils in Tribol 943 AW are selected for chemical ａnd thermal stability. They are also selected for the naturally high film strength necessary to prevent rupture at the highest pump pressures ａnd tightest clearances where operating conditions usually lead to mixed or boundary (contact) lubrication. The premium base oils also maintain unsurpassed cleanliness, therefore minimizing formation of varnish deposits ａnd wear debris in any system.  The anti-wear characteristics of Tribol 943 AW oils are achieved by a unique additive system which does not include zinc. The advanced anti-wear additive systems maintain critical dimensions in robots ａnd other NC machines, therefore extending the service life of valves, pumps, gears, ａnd bearings.  Tribol 943 AW oils do not contain silicone ａnd are free of lead, zinc, chlorinated solvents ａnd barium. They contain less than 2 ppm of phenol. They are formulated to address environmental concerns.  The unsurpassed oxidation stability of Tribol 943 AW oils is a result of extensive research to stabilize petroleum oils at high operating temperatures. The balanced, total additive system in Tribol 943 AW oils also inhibits foaming ａnd provides an unusual degree of corrosion protection see Typical Characteristics.
