GE Seal

Gear System Leakage Control & Sealing Support

GE Seal is designed for mineral oil-based gear systems affected by oil leakage, seal wear, or unstable operating conditions. Once dispersed in the gear oil, PTFE particles help accumulate in worn sealing areas and leakage paths, supporting reduced oil loss and more stable gear system operation over time.

System Compatibility & Blending
GE Seal treatments are based on high-quality mineral gear oil and are designed to blend with most commonly used mineral gear lubricants. The product is added to the relevant gear oil system according to the recommended dosage and application guidance.

Oil Compatibility Note
GE Seal is intended for selected mineral oil-based gear systems. For EAL or bio-oil systems, compatibility must be reviewed separately based on oil type, viscosity, additive package, leakage condition, system condition, and operating environment.

Suitable System Types
GE Seal can be considered for selected mineral oil-based gear systems, including industrial gearboxes, marine gear systems, drive units, gear housings, gear teeth, bearings, and loaded contact surfaces where oil leakage, seal wear, heat, vibration, or unstable operation are key concerns.

The correct Gear Seal variant — Core, Plus, or Max — is recommended based on leakage level, oil volume, system condition, seal arrangement, gear type, load conditions, temperature profile, and operating environment.

Assessment Before Application
Before treatment, we review the gear system type, seal condition, leakage level, oil type, viscosity, oil volume, filtration, gear condition, load profile, temperature conditions, operating environment, and service objective. This allows us to recommend the most suitable Gear Seal variant, dosage, and application approach for the specific case.

the system, seal arrangement, lubricant, oil volume, filtration, and operating conditions.

Application Example

Minor Leakage - Support for an Industrial Gearbox

Gear Seal Core - Standard Sealing Support for an Industrial Gearbox

System type: Industrial gearbox
Gear oil volume: ~600 L
Estimated leakage: ~5 L/day

Scenario
During regular operation, the maintenance team observed consistent low-level oil leakage from the gearbox. The system remained operational, but the leakage required regular monitoring and oil top-up. While not critical, the issue indicated possible wear in sealing areas and raised concern about long-term gearbox reliability and oil condition.

Action
The operator contacted Addvation to assess the situation. Based on gearbox type, oil volume, observed leakage, seal condition, and operating profile, Gear Seal Core was recommended as a starting point.

Recommended starting point: Gear Seal Core

Indicative quantity: ~40 L total

Application
The product was applied during a planned maintenance window, following the recommended dosage and application guidance.

Outcome
Leakage was reduced and stabilized, supporting continued operation without further escalation or need for immediate repair.

Moderate Leakage - Reinforced Sealing Support for an Industrial Gearbox

Gear Seal Plus – Reinforced Sealing Support for an Industrial Gearbox

System type: Industrial gearbox under continuous production load
Gear oil volume: ~1,200 L
Estimated leakage: ~15–20 L/day
Observed issue: External oil leakage around gearbox seals and increasing vibration under load

Scenario
During production, the gearbox experienced increasing oil leakage around the main sealing areas. The system remained operational, but leakage increased during higher load periods, requiring regular oil top-up and cleaning around the equipment. The maintenance team also observed increased vibration and elevated operating temperatures, indicating progressing seal wear and higher mechanical stress.

Action
The operator contacted Addvation to assess the situation before the next planned maintenance window. Based on the gear oil volume, leakage level, seal condition, vibration, temperature profile, and operating demands, a reinforced sealing approach was recommended.

Recommended starting point: Gear Seal Plus

Indicative quantity: ~70 L total

Application
The product was added to the gear oil system during a planned maintenance stop, following the recommended dosage and application guidance.

Outcome
Leakage around the gearbox sealing areas was reduced and stabilized. The system required less frequent oil top-up, vibration and operating stability improved, and the operator was able to continue production until planned maintenance.

High Leakage - Maximum Sealing Support for a Heavy Industrial Gearbox

Application Scenario
Gear Seal Max – Maximum Sealing Support for a Heavy Industrial Gearbox

System type: Heavy industrial gearbox under high-load operation
Gear oil volume: ~4,500 L
Estimated leakage: ~70–80 L/day
Observed issue: Significant external oil leakage around gearbox seals, increased vibration, and unstable operating conditions

Scenario
During production, the gearbox experienced a significant increase in oil leakage around several main sealing areas. The leakage level created immediate operational concern, including high oil consumption, frequent cleaning around the equipment, increased vibration, and elevated operating temperatures during demanding load cycles. The issue indicated advanced seal wear and created pressure to avoid an unplanned shutdown before scheduled maintenance.

Action
The operator contacted Addvation to assess the situation before the next planned maintenance stop. Based on gearbox size, leakage severity, seal condition, vibration, temperature profile, and operating demands, a maximum sealing support approach was recommended.

Recommended starting point: Gear Seal Max

Indicative quantity: ~230 L total

Application
The product was added to the gear oil system during a planned service window, following the recommended dosage and application guidance.

Outcome
Leakage around the gearbox sealing areas was reduced to a more stable operating level. Oil consumption was reduced, operating stability improved, and the operator was able to continue production until planned maintenance without immediate shutdown.
