Castrol Tribol HM 943-68 Bearing and Circulating Oil
Description
Castrol Tribol™ HM 943 Range (previously called 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 emphasised: 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.Additional Information

| Features and Benefits | The base oils in Tribol HM 943 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 minimising formation of varnish deposits and wear debris in any system., The anti-wear characteristics of Tribol HM 943 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., The unsurpassed oxidation stability of Tribol HM 943 oils is a result of extensive research to stabilise petroleum oils at high operating temperatures. The balanced, total additive system in Tribol HM 943 oils also inhibits foaming and provides an unusual degree of corrosion protection see Typical Characteristics |
