Description
Castrol Alpha EP 100 is a mineral‑oil based industrial gear lubricant in the Alpha EP range that fulfills DIN 51517‑3 CLP requirements and delivers good wear protection, resistance to scuffing, thermal stability, and aging resistance. It’s suitable for a wide range of enclosed gearboxes and heavy‑duty industrial transmissions where strong extreme‑pressure performance is needed.
This 20 L canister size is practical for maintenance servicing and refilling gear oil reservoirs on machinery with smaller oil capacities. The product’s balanced viscosity and additive package help maintain smooth gear operation, protect metal surfaces from wear, and extend component life.
