Bearings for Blown Film Extrusion Machines
Bearings used in blown film extrusion machines operate under continuous load, elevated temperatures and variable speeds. These applications require dependable components that ensure smooth rotation of rollers, calibration cages, cooling rings and winding units. Whether you need standard deep groove ball bearings, cylindrical roller bearings or high-precision units, we can supply the exact specification required for your equipment.
Reliable Bearings for Film Production Lines
Blown film extruders depend on highly stable and durable bearings. These components must handle continuous rotation, vibration, moisture and thermal expansion. Using the correct bearing type directly improves film quality, thickness accuracy and overall machine efficiency.
We supply bearings for all critical points of the production line, including:
- Air rings and cooling systems
- Calibration cages and guide rollers
- Haul-off units and nip rollers
- Winders and tension control systems
- Gearboxes and drive shafts
- Extruder auxiliary systems
Types of Bearings Commonly Used
- Deep groove ball bearings – universal use, quiet operation
- Cylindrical roller bearings – high radial load capacity
- Tapered roller bearings – suitable for combined loads
- Self-aligning ball bearings – compensate for misalignment
- Needle roller bearings – compact design, high load capacity
- Precision bearings – for high-speed winding systems
