Tandem Bearing<\/h1><\/div>\n\n\n\n

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.<\/p><\/div>\n\n\n\n

They are designed to provide increased load-carrying capacity and rigidity compared to single-row bearings.<\/p><\/div>\n\n\n\n

ZMS is a professional supplier of tandem bearings in China that supply high quality a good substitute of famous brand like INA, ROLLWAY.<\/p><\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n

High Axial Load Capacity<\/strong>: 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<\/strong>: Provides high load capacity in a compact footprint, suitable for space-constrained machinery.

Low Friction and High Precision<\/strong>: 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.<\/p><\/div><\/div><\/div>\n<\/div>\n<\/div>\n\n\n\n

Extruders (Plastic and Rubber Processing):<\/strong>
\u2022 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.
\u2022 Example: Twin-screw extruders in polymer manufacturing.

Gearboxes (Industrial and Wind Turbines):<\/strong>
\u2022 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.
\u2022 Example: Wind turbine gearboxes, where they support the axial forces from the rotor and gears, enhancing durability and efficiency.

Rolling Mills<\/strong>:
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.<\/p><\/div><\/div><\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n

Multi-Stage Design for Massive Axial Loads<\/strong><\/h2>\n\n\n\n

Tandem bearings are highly specialized components engineered to accommodate extreme axial forces within a severely restricted radial envelope. By stacking multiple stages of thrust cylindrical roller bearings in series (tandem), the ZMS tandem bearing design distributes massive thrust loads evenly across two, three, four, or more stages. This unique configuration multiplies the axial load capacity significantly without increasing the outer diameter of the housing.<\/p>\n\n\n\n

The Ultimate Solution for Twin-Screw Extruders<\/strong><\/h2>\n\n\n\n

The plastic and rubber extrusion industries demand continuous operation under immense pressure. ZMS tandem bearings are the preferred choice for twin-screw extruder gearboxes<\/strong>. In these applications, the center distance between the two screw shafts is extremely tight, making standard heavy-duty thrust bearings impossible to install. Our multi-stage design solves this spatial limitation, ensuring reliable gear meshing, preventing shaft deflection, and maximizing the service life of your extrusion equipment.<\/p>\n\n\n\n

Engineered for Uniform Load Distribution<\/strong><\/h2>\n\n\n\n

A critical challenge in multi-stage bearing design is ensuring that every row carries its fair share of the load. ZMS tandem bearings utilize precisely manufactured thick-walled outer rings and high-quality calibrated elastic compression sleeves (spring rings). This advanced internal engineering ensures uniform load sharing across all stages, preventing premature failure of any single row and guaranteeing smooth, low-friction rotation.<\/p>\n\n\n\n
