Description
Castrol Alphasyn PG 320 gear oils (CLP, ISO VG 320) are high quality synthetic lubricants based on polyglycole (PG) fluids.
- Pack size: 208 l drum
- Also available in: 20 l canister
Application
- Alphasyn PG gear oils are primarily intended for use in worm reduction gear boxes, where the low coefficient of friction of the PAG base fluid improves efficiency and consequently reduces power consumption and operating temperatures. This is particularly important in applications where sliding contact is high.
Specifications & Approvals
- DIN 51517, Teil 3, CLP
- ISO 6743/6-L-CKT
Advantages
- Low coefficient of friction reduces energy consumption and lowers operating temperatures, this leads to longer oil life.
- Good thermal and oxidative stability provides reliable operation and extended operating life when compared to mineral oil based products.
- Inherently high VI makes the product suitable for operations over a wide temperature range.
- High load carrying capacity and good wear protection reduces maintenance.
