Aerospace and Defence in Gear & Bearing Oils
In Aerospace and Defence, equipment availability converts directly into cost. Gear & Bearing Oils look like a small line in that budget, yet the wrong choice is one of the most common causes of unplanned downtime. This page sets out where this product group is used in the sector and which criteria decide the selection.
Why it matters in this sector
Gear oils have to carry the high contact pressure on tooth flanks. The EP additive package delays pitting and micropitting, and synthetic products give a clear life advantage at high temperature.
For bearing and circulation oils the priorities are heat removal, water separation and long service without deposits. Circulation systems in paper, steel and power plants are typical applications.
Selection criteria
- The equipment builder's approval list and minimum performance level
- Operating temperature range and ambient conditions (humidity, salt air, dust)
- Whether the viscosity grade suits the load and speed profile
- Balance between drain interval and total cost of ownership
- Packaging type and how it fits the plant's internal transfer set-up
