Engineering Analysis, Failure Diagnosis and Performance Optimisation for Critical Rotating Equipment
Specialist technical services for hydrodynamic bearings — helping operators, OEMs and service providers diagnose issues, improve performance and prevent future failures.
Oiltech provides engineering-led technical services to solve complex bearing and rotating equipment challenges.
Combining practical experience with advanced analysis tools, we support clients in diagnosing failures, improving performance and ensuring long-term reliability of critical machinery.
When To Engage Oiltech
Our technical services are typically required when:
- A bearing failure has occurred and the root cause is unclear
- Equipment is experiencing vibration, instability or overheating
- Performance is below expected levels
- A design is no longer suitable for current operating conditions
- A new or modified application requires engineering validation
Core Technical Capabilities
Failure Analysis & Root Cause Investigation
Understanding why a bearing failed is critical to preventing recurrence.
- Detailed inspection and failure mode identification
- Analysis of operating conditions and system behaviour
- Identification of underlying causes (not just symptoms)
- Practical recommendations to prevent repeat failures
Bearing Design & Performance Analysis
Engineering support for both new and existing applications.
- Bearing geometry design and optimisation
- Load, speed and lubrication evaluation
- Application-specific performance modelling
- Verification of operating limits and safety margins
Oil Film & Performance Modelling
Advanced analysis of hydrodynamic bearing behaviour.
- Oil film pressure and temperature distribution
- Minimum film thickness evaluation
- Power loss and thermal performance
- Stability characteristics and damping behaviour
This enables optimisation of bearing performance in high-speed turbomachinery.
Re-Engineering & Design Optimisation
Improving performance beyond original specifications.
- Redesign of existing bearings
- Upgrades for increased load or speed
- Modification of lubrication systems
- Adaptation to changing operating conditions
