Sapsons Hydraulic Bearing Pullers are heavy-duty tools designed for the safe, efficient removal of bearings, gears, and pulleys from shafts without causing damage. These industrial tools offer high force, often using self-contained or hand-pump-operated hydraulic power for secure, controlled dismounting in industrial applications.
Main Components
1. Hydraulic cylinder (ram)
2. Pump (manual or electric operated)
3. Puller head
4. Adjustable arms / jaws (2 or 3 legs)
5. Center bolt / spindle
6. High-pressure hose (in some models)
Material
Made from high-strength alloy steel
Heat-treated jaws for durability
Corrosion-resistant coated body
Working Principle
The hydraulic pump creates pressure inside the cylinder.
This pressure pushes the ram forward, which applies strong pulling force through the jaws to remove the bearing from the shaft without damaging surrounding parts.
Key Features and Design
Sapsons hydraulic pullers are engineered to minimize machine downtime and prevent damage to expensive components like shafts and housings.
Integrated and Separate Pump Options: Depending on the model, these pullers may feature an inbuilt hydraulic pump for one-person operation or connect to a separate hand pump via a high-pressure hose for greater control in tight spaces.
Adjustable Jaw Configurations: Most models allow users to switch between 2-jaw and 3-jaw setups to adapt to different component shapes and provide a stable, even grip.
Material and Durability: Constructed from high-strength forged alloy steel with special heat treatments to ensure longevity under heavy industrial loads.
Safety Mechanisms: Systems often include safety release valves to prevent overloading, protecting both the tool and the operator.
Typical Specifications
Light Duty (5–10 Tons): Suitable for passenger vehicles and small industrial motors.
Medium Duty (15–20 Tons): Common for heavy trucks, agricultural equipment, and larger gearboxes.
Heavy Duty (30–50+ Tons): Specialized units for mining, construction, and large-scale manufacturing machinery.
Applications:
1.Power Plants
In power plants such as NTPC and BHEL projects, hydraulic pullers are used for:
• Removing turbine bearings
• Dismantling pump assemblies
• Maintenance of generators and motors
2. Steel & Heavy Industries
Used for:
• Removing large gears from rolling mills
• Dismantling heavy-duty shafts
• Maintenance of conveyor systems
3. Railways
In organizations like Indian Railways:
• Wheel bearing removal
• Axle maintenance
• Locomotive repair work
4. Automobile Workshops
• Removing wheel hub bearings
• Pulling crankshaft gears
• Servicing transmission components
5. Industrial Maintenance
• Removing seized or rusted bearings
• Extracting pulleys and couplings
• Repairing electric motors
6. Mining & Construction Equipment
• Maintenance of excavators
• Dismantling gearbox components
• Removing large mechanical assemblies
Why It Is Preferred in Applications:
• Provides high pulling force with less effort (5 Ton to 100 Ton or more)
• Prevents damage to costly shafts and bearings
• Ensures safe and controlled dismantling/ operation
• Saves time during shutdown maintenance
• Suitable for tight and heavy fittings
Important Notes
Always select correct tonnage capacity.
Ensure jaws are properly aligned before applying pressure.
Do not exceed rated pressure limit.
Use safety gloves and goggles during operation.
