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. Antiwear 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.
Hydraulics - designed for the most sophisticated hydraulic operations, robots, and other NC machines, Tribol HM 943 oils may be used in any industrial, marine, or mobile applications.
Circulating systems - outstanding anti-wear properties make Tribol HM 943 AW oils ideal for multi-component systems including anti-friction and journal bearings and all types of gears except where manufacturers specify AGMA "EP" or “Compounded” gear oils.
Compressors – Tribol HM 943/32 and Tribol HM 943/46 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 HM 943 applications provides excellent opportunity to consolidate inventory.
The Tribol HM 943 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.
