Zhejiang Waxing Electromechanical Co., Ltd is one of the most professional manufacturers and suppliers of 81144m unidirectional thrust cylindrical roller bearing in China. Welcome to buy high quality customized bearings made in China here from our factory. For price consultation, contact us.
81144M is a unidirectional thrust cylindrical roller bearing (with machined brass cage), designed to withstand extremely large unidirectional axial loads, low-speed high rigidity working conditions.
main advantages
1. Ultra high axial bearing capacity: The cylindrical roller line contact design increases the bearing capacity several times compared to thrust ball bearings of the same size, making it suitable for overweight loads.
2. High rigidity and impact resistance: The solid brass cage has high strength, smooth operation, and resistance to vibration and impact loads.
3. Low friction and heat generation: The roller and raceway are precisely matched, and the lubrication requirements are relatively low, making it suitable for long-term heavy load operation.
4. Separable design: Components can be disassembled and installed for easy maintenance and clearance adjustment.
Typical usage scenarios
-Metallurgical mining equipment: hydraulic cylinders for rolling mills, winches, and axial positioning of main shafts for large crushers.
-Heavy Machinery and Engineering: Crane slewing bearings, shield tunneling machine top push systems, large valve actuators.
-Industrial furnaces and welding: trolley furnace track support, quenching machine lifting mechanism, large welding machine and pressure shaft.
-Machine tool and power transmission: Large boring machine spindle axial fixation, heavy-duty screw pump, low-speed high torque reducer output end.
