Tandem Bearing

Tandem bearings also known as tandem roller bearings or multi-row bearings are designed to support high axial loads in one direction. There are two rows, three rows, four rows, five rows, six rows and eight rows. They can also with shaft or sleeve.

They are designed to provide increased load-carrying capacity and rigidity compared to single-row bearings.

ZMS is a professional supplier of tandem bearings in China that supply high quality a good substitute of famous brand like INA, ROLLWAY.

Feature

High Axial Load Capacity: The multi-row cylindrical roller design distributes axial loads across several rows, allowing these bearings to handle significantly higher loads than single-row bearings.

Compact and Robust Design: Provides high load capacity in a compact footprint, suitable for space-constrained machinery.

Low Friction and High Precision: Cylindrical rollers reduce friction and maintain alignment, ensuring smooth operation and minimal wear.
Durability: Designed to withstand heavy loads and harsh conditions, improving the lifespan of the equipment.

Applications

Extruders (Plastic and Rubber Processing):
• Tandem cylindrical roller bearings are extensively used in extrusion machines, where they support the screw that generates significant axial thrust during the processing of materials like plastics, rubber, or food products. Their high axial load capacity and rigidity ensure reliable performance under continuous high-pressure conditions.
• Example: Twin-screw extruders in polymer manufacturing.

Gearboxes (Industrial and Wind Turbines):
• These bearings are employed in heavy-duty gearboxes, particularly in planetary gear systems, to manage axial loads from gear meshing. Their ability to handle high loads while maintaining precision makes them ideal for demanding applications.
• Example: Wind turbine gearboxes, where they support the axial forces from the rotor and gears, enhancing durability and efficiency.

Rolling Mills:
In metal rolling mills, tandem cylindrical roller bearings are used to support rolls that apply high axial forces to shape metal sheets or bars. Their robust design ensures stability and precision during the rolling process.
Example: Cold rolling mills for steel or aluminum production.
