Further Details:

SERIES 'DWT-MOT':

Our automated hydraulic bearing extractor's series of DWT MOT is uniquely composed reduced, versatile instrument for demounting shrink fitted round shaped roller bearing on Indian Railways EMUs as well as tubular shaped wheel sets journal of ICF coaches, i.e., MG or BG.

This product is the new addition to our array of hydraulic extractors grounded on system of oil injection as well as has higher efficiency to the physically operated extractors.

Principle:

Process of demounting is completely grounded on the system of oil injection. In this system, pressurized oil is infused between the journal and the bearing surface and created a sleek oil layer removing contact of metal to metal. The bearing for practically drifts out on oil layer without journal scoring.

Design Features:

The Extractor comprises of a portable Workstation affixed with reduced Hydraulic Energy-Pack possessing constructed safety devices and controls.
Our automated hydraulic bearing extractor possesses double settled wheels in fore side and double swivel castors at the back of hydraulic parts of the main force origin of 150 bars (optimum) as well as the different compartment possesses an intensifier for infusion of oil to create the force of bars that are 750 in number.
The dismounting accessories and tools are exceptionally intended to stimulate oil infusing at elevated force between the tube shaped journal and the shrink fit bearing internal ring, for simple and easy dismounting.
The mechanized hydraulic energy pack with infusion of oil system of our instrument enables the bearing withdrawal protected and easy.
The quick acting hydraulic withdrawal apparatus guarantees that the pivotal removal of bearing is quick, without utilization of manual pressure.
If there should be an occurrence of energy failure or if there should arise an occurrence of field workings when the Digital Hydraulic Extractor's Energy-Pack is impossible to be utilized, as a support through the unit is furnished with double sets of physically worked Oil Injectors that comes with foot-stand as well as different embellishments and single Cranking Jack Machine, to be utilized for Physical Withdrawal Process.

Computerized Hydraulic Bearing Extractor With The System Of Oil Injection

For demounting roller orientation contracted fitted (i.e. coordinate mounted) on barrel shaped diaries of ICF Coaches wheel sets (MG/BG) as well as Indian Railways EMUs.

Powerful and Versatile Extraction

This hydraulic bearing extractor delivers up to 700 bar of pressure, allowing operators to efficiently remove spherical roller bearings from heavy machinery. It suits a wide range of inner diameters (25-200 mm) and outer diameters (up to 400 mm), making it compatible with numerous industrial bearing types in demanding environments, including steel plants and rail workshops.

Advanced Safety and Control Features

With an integrated electrical control panel and emergency stop, this unit prioritizes operator safety. The inclusion of overload protection and a pressure relief valve helps prevent system failures during operation. Built-in hydraulic oil lubrication and high-grade seals ensure smooth extraction and longevity, even under continuous, high-pressure use.

Mobility and Customization

Weighing approximately 120 kg and equipped with rugged wheels, this extractor is designed for easy transport across the factory floor. Multiple configuration options-such as drive motor power, extraction stroke length, and electrical supply-allow customization for specific industrial needs, backed by a one-year warranty and comprehensive after-sales support.

FAQ's of Automated Hydraulic Bearing Extractor:

Q: How does the Automated Hydraulic Bearing Extractor function during the bearing removal process?

A: The extractor utilizes high-pressure hydraulics, powered by a 2 H.P. motor (custom options available), to apply force directly to the bearing. Operators use the integrated control panel to manage the extraction, with safety features ensuring that overloads or excessive pressures are immediately addressed. Hydraulic oil lubrication is applied throughout the extraction for smooth operation and protection of components.

Q: What types of bearings and applications is this extractor suitable for?

A: This unit is engineered to handle all standard industrial bearings, particularly spherical roller bearings shrink-fitted on cylindrical journals. It's ideal for use in sectors like steel plants, power plants, heavy manufacturing, and railway workshops, making the dismounting of bearings quick and reliable for inner diameters of 25 mm to 200 mm and outer diameters up to 400 mm.

Q: When is it recommended to use this hydraulic extractor over manual methods?

A: The extractor should be used whenever high forces are necessary-especially when dealing with shrink-fitted or heavily mounted bearings where manual removal is impractical, unsafe, or risks damaging expensive components. It is particularly beneficial for frequent, heavy-duty extraction tasks demanding precision and repeatability.

Q: Where can this hydraulic bearing extractor be deployed within industrial facilities?

A: Thanks to its mobility and robust construction, the extractor can be easily transported to different locations within steel plants, rail workshops, mining sites, and heavy manufacturing units. Its portable design allows on-site extraction, reducing downtime by eliminating the need to transport equipment to a central workshop.

Q: What benefits does the overload protection and pressure relief valve provide during use?

A: Overload protection and the pressure relief valve safeguard both the machine and operator during extraction by automatically halting operation in case of excessive force or system stress. This reduces the risk of equipment failure, bearing damage, or operator injury, thereby enhancing workplace safety and operational efficiency.

Q: How is the extractor maintained for optimal performance and longevity?

A: Routine maintenance includes inspecting hydraulic seals, checking hydraulic oil levels, and ensuring the control panel and safety systems are fully operational. Periodic lubrication, as well as prompt attention to any leaks or performance declines, will ensure sustained high-pressure capability and safe use over time.

Q: What warranty and support services are provided for this extractor?

A: Each Automated Hydraulic Bearing Extractor comes with a one-year warranty covering manufacturing defects. Comprehensive after-sales support is available, including spare parts, customization of configurations, and technical guidance for trouble-free operation.
