Typical Application Scenarios (Common for 65mm Shaft Diameter)

1. Metallurgy/Steel (Main Application)
Continuous casting machine rollers, rolling mill auxiliary rollers, heating furnace rollers, bar/wire conveyor rollers, cooling beds, straighteners, coilers, walking beams

2. Mining/Coal
Belt conveyors (head/tail pulleys, tensioning pulleys, idlers), scraper conveyors, crushers, vibrating screens, bucket wheel excavators, ball mills, coal mills, transfer conveyors

3. Cement/Building Materials
Rotary kiln support rollers, grate coolers, roller presses, air classifiers, elevators, clinker conveyors, lime kilns, tube mills

4. Power (Thermal/Hydropower/Wind Power)
Induced draft fans, forced draft fans, dust collectors, water pumps, coal mills, cooling tower fans, turbine guide bearings, wind turbine yaw/pitch bearings

5. Paper/ Printing: Paper machine press rolls, drying cylinders, rewinders, coating machines, calenders, conveyor rolls, paper winding machines

6. Ports / Cranes / General Industry: Stacker-reclaimers, gantry cranes, overhead cranes, ship loaders, ship unloaders, centrifugal pumps, Roots blowers, gearbox output shafts (positioning ends), mixing equipment

Model Type Core Function Applicable Scenarios

01EB65MGR Positioning Type Fixed shaft end, withstands radial + unidirectional axial force. For fixed ends where shaft movement needs to be limited and axial force is required.

01EB65MEX Floating Type Only withstands radial force, allows axial thermal expansion and contraction of the shaft. For floating ends where the shaft needs free expansion and contraction (paired with MGR).

01B65MGR Older Positioning Type Similar size, slightly lower load. For replacing older equipment, limited budget, and low load requirements.

Metallurgy / Steel (Main Application)

1. Continuous Casting Machine Roller Bearings (Fixed End)

Case Study: Slab continuous casting machine fan-shaped section rollers and conveyor rollers (shaft diameter 70mm) in a domestic steel plant

Operating Conditions: Continuous operation, high temperature (80–120℃), dust, water spray, medium to heavy load + impact

Selection Logic: Fixed end uses 01EB70MGR (positioning, withstands radial + axial forces)
Floating end uses 01EB70MEX (radial only, allows thermal expansion)
Split Design: No need to disassemble the roller conveyor frame/coupling, reducing replacement time from 8–12 hours to 40 minutes

Benefits: Annual downtime loss per continuous casting machine reduced by approximately 500,000–800,000 RMB

2. Rolling Mill Auxiliary Rolls / Heating Furnace Rolls

Case Study: Guide rollers, looper rollers, and heating furnace discharge rollers for bar/wire mills

Operating Conditions: High temperature, dust, frequent start-stop, strict axial movement control

Advantages: Triple labyrinth seal + Split design, adaptable to harsh working conditions; 01E reinforced version increases load capacity by 30% and extends lifespan by 40%.

3. Cooling Bed / Straightener / Winder

Case Studies: Cooling bed walking beam, straightener work roll, winder tension roll (70mm shaft)

Pain Point: Traditional bearing replacement requires disassembling the gearbox/motor, resulting in downtime exceeding 1 day.

Solution: 01EB70MGR + 01EB70MEX pairing, shaft replacement without disassembly, downtime < 1 hour.
