Journal Bearings
New Journal Bearings Designed and Manufactured In-House
At Revak Keene, we don’t just repair bearings — we also design and manufacture new journal bearings in-house. Our team works with advanced materials and techniques to ensure that each bearing is built to meet your machinery’s precise specifications. Whether you’re looking to replace an existing bearing or need a custom design, we deliver high-quality, OEM-standard bearings that ensure long-lasting performance and reliability.
Journal Bearing Overview:
Journal bearings are designed to support radial loads and are commonly used in high-speed machinery such as steam turbines and pumps. They work by creating a hydrodynamic film that separates the rotating shaft from the bearing surface, ensuring smooth operation with minimal friction.
Key Features:
- Supports radial loads in rotating machinery.
- Utilizes a hydrodynamic film for low friction and high efficiency.
- Ideal for use in steam turbines, pumps, and rotating equipment.
Common Failures:
- Fatigue due to repetitive stress.
- Electrolysis causing pitting and wear.
- Separation of babbitt material from the base metal.
Services:
- In-house repair and manufacturing.
- Refurbishment to OEM standards or better.
- Retrofit and custom solutions for upgraded performance.
Thrust Bearings
Custom Thrust Bearings Manufactured to Exceed OEM Standards
In addition to repairs and retrofits, Revak Keene manufactures new thrust bearings that are designed to handle high axial loads with precision. Our team uses advanced materials and engineering to ensure that every new thrust bearing meets or exceeds OEM standards, ensuring the highest level of performance for your machinery.
Thrust Bearing Overview
Thrust bearings are essential for supporting axial loads and preventing shaft displacement. These bearings are vital in maintaining alignment and ensuring the stability of the rotating parts in machinery such as pumps, turbines, and compressors.
Key Features:
- Handles axial loads to prevent shaft displacement.
- Maintains proper alignment and stability.
- Commonly used in high-load turbines and compressors.
Common Failures:
- Pitting due to contaminated lubrication.
- Fatigue cracks from high-load cycles.
- Cavitation from improper lubrication.
Services:
- NDE inspections to identify wear and fatigue.
- In-house refurbishment and new designs.
- Reverse engineering for custom solutions.
Sleeve Bearings
New Sleeve Bearings Tailored for High-Speed Applications
When you need new sleeve bearings, look no further than Revak Keene. Our in-house manufacturing team creates custom sleeve bearings designed for high-speed, low-friction applications. We tailor each bearing to meet the specific needs of your equipment, ensuring superior performance and extended service life.
Sleeve Bearing Overview
Sleeve bearings provide low-friction performance in high-speed applications by creating a sliding motion between the shaft and the bearing. These bearings are commonly used in rotating equipment such as electric motors and fans.
Key Features:
- Low-friction design for high-speed operation.
- Supports rotational motion in various industries.
- Suitable for use in electric motors, fans, and pumps.
Common Failures:
- Overheating due to lubrication failure.
- Scoring caused by contaminants.
- Wiping from excessive heat or overload.
Services:
- Custom manufacturing and refurbishment.
- Lubrication management to prevent overheating.
- Precision alignment to minimize wear.
Tilt-Pad Bearings
Manufacturing New Tilt-Pad Bearings for Stability and Precision
At Revak Keene, we design and manufacture new tilt-pad bearings that provide the stability and adaptability needed for fluctuating loads and misalignment. Our in-house capabilities ensure that each tilt-pad bearing is customized to your equipment, offering long-term reliability and performance that surpasses industry standards.
Tilt-Pad Bearing Overview
Tilt-pad bearings are highly adaptable and can accommodate misalignment and fluctuating loads. They are used in machinery where stability is critical, such as turbines and compressors. These bearings reduce vibration and increase the overall reliability of the machine.
Key Features:
- Accommodates misalignment and fluctuating loads.
- Reduces vibration for stable operation.
- Common in high-speed turbines and compressors.
Common Failures:
- Vibration fatigue from excessive use.
- Erosion from improper lubrication.
- Separation due to material fatigue.
Services:
- Complete in-house design and production.
- Refurbishment to ensure long-term reliability.
- Rotordynamic analysis for vibration reduction.
Comprehensive Bearing Services
- Non-Destructive Examination (NDE): Using cutting-edge technology, we inspect for potential flaws or defects in bearing surfaces, ensuring operational integrity without damage. This inspection meets the highest industry quality standards for critical rotating equipment.
- Refurbishment and Rebuilds: Bearings undergo wear due to dynamic loads, misalignment, and improper lubrication. At Revak Keene, we restore worn or damaged bearings to like-new condition, extending their service life through precise re-engineering and material upgrades.
- Retrofit and Modifications: When machinery evolves, so too must its components. Our retrofitting services ensure that existing bearings are modified or adapted to meet new specifications, ensuring compatibility and enhanced performance.
- New Bearing Designs: Our in-house team designs new bearings from the ground up, ensuring they are tailored to each specific application, whether it's for a steam turbine, pump, or small prime mover. All designs comply with industry best practices, guaranteeing superior durability and performance.
