Combined Bearings Series ZARN

The ZARN series combined bearings ingeniously combine radial bearings and thrust bearings. The rolling elements in the radial part fit closely with the raceway and are responsible for carrying radial loads to ensure the smooth operation of the equipment; the thrust part accurately handles axial loads. The two work together to adapt to complex force conditions.

Combined Structure：The ZARN series combined bearings ingeniously combine radial bearings and thrust bearings. The rolling elements in the radial part fit closely with the raceway and are responsible for carrying radial loads to ensure the smooth operation of the equipment; the thrust part accurately handles axial loads. The two work together to adapt to complex force conditions.

Superior Combined Load-bearing Capacity：The unique combined design endows it with both radial and axial load-bearing capacities. It can simultaneously bear extremely large radial and axial loads and is widely used in fields with demanding load-bearing requirements, such as heavy machinery and large rotating equipment.
High Operational Stability：The precise cooperation of all components results in small vibration and low noise during operation. It can maintain stability under complex working conditions such as high-speed operation and frequent start-stop, reducing the risk of equipment failure and extending the life span.
Flexible Adaptability to Working Conditions：It can meet the operation requirements of wind power equipment in outdoor complex climates and variable loads, and also adapt to the strict requirements of industrial machine tools for bearings during high-speed and high-precision machining, with strong versatility.

Application

The bearings can be used in the following industries

Energy and Power：The spindle bearings of wind turbines, hydro turbines and other equipment often use this type, bearing the complex forces brought by blade rotation, ensuring power generation efficiency and equipment stability.
Heavy Industrial Manufacturing：Large rolling mills, mining crushers and other heavy machinery rely on it to bear huge production loads, ensuring continuous production and increasing production capacity.
Transportation Equipment：The key rotating parts of ship propellers and railway locomotives cope with the force changes under high-speed operation and frequent speed changes, ensuring operational safety.
