81207Cylindrical Roller Thrust Bearings

81207 Thrust Cylindrical Roller Bearing | 81207TN And 81207M Cage And Application

The 81207 is a robust single-direction thrust cylindrical roller bearing with standard dimensions of 35×62×18mm. Engineered for pure unidirectional axial thrust loads, this bearing delivers exceptional structural rigidity, strong pressure resistance and consistent low-speed operational stability. It effectively restricts shaft axial displacement, absorbs continuous heavy thrust pressure and mechanical vibration, and maintains precise shaft positioning during long-cycle industrial operation. Featuring dense cylindrical roller arrangement, the 81207 offers upgraded load capacity and structural stability, perfectly suited for medium and heavy-duty thrust mechanical systems. The series provides two practical configurations: 81207TN nylon cage model and 81207M solid brass cage model for standard and harsh working environments.

81207TN Bearing (Nylon PA66 Cage)

81207TN adopts a high-strength injection-moldedPA66 nylon cage, serving as the economical and universal standard version. The lightweight, high-toughness nylon retainer ensures smooth and precise roller circulation, effectively reducing running friction and operational noise during continuous medium-load operation. It features a low friction coefficient, excellent lubricity and reliable anti-fatigue performance, avoiding rigid metal friction and internal component abrasion. The corrosion-resistant nylon structure protects internal rollers and retains lubricant stability, extending overall service life. Ideal for clean, normal-temperature and conventional industrial conditions, 81207TN delivers stable performance and cost advantages for general thrust transmission equipment.

81207M Bearing (Solid Brass Cage)

81207M is equipped with a precision machined solid brass cage, designed for extreme heavy-duty and high-temperature working scenarios. The high-rigidity integral brass cage boasts superior thermal stability, structural strength and shock resistance compared with nylon cages. It maintains accurate roller spacing and complete structural integrity under high temperatures, instantaneous heavy thrust loads and long-term uninterrupted operation. This effectively prevents roller skew, structural deformation and premature wear, greatly enhancing bearing durability and operational reliability. As a premium heavy-duty model, 81207M is widely used in critical core equipment that requires zero-failure continuous operation in complex and harsh industrial environments.

Bearing Material And Structural Advantages

All 81207 series bearings are manufactured from high-purity chrome bearing steel. After integral quenching treatment and ultra-precision surface grinding, the raceways and cylindrical rollers achieve high hardness, outstanding wear resistance and stable mechanical properties. The flat raceway design ensures uniform force distribution, eliminates local stress concentration, and minimizes elastic deformation under heavy loads. Its compact high-rigidity structure supports stable heavy axial thrust bearing capacity, guaranteeing long-term precise positioning and reliable operation of mechanical shafts.

Industrial Applications

81207 thrust cylindrical roller bearings are widely applied in medium and heavy-thrust industrial equipment for axial load support and shaft limiting positioning. 81207TN is suitable for general heavy machinery, medium-sized gear reducers, automated production lines and conventional transmission systems. 81207M fits rigorous working scenarios including high-temperature processing equipment, hydraulic systems, mining auxiliary machinery and heavy industrial devices with continuous heavy-load and impact operation.

Product Summary: The 81207 bearing features high rigidity and powerful heavy-thrust bearing capacity for medium and heavy-duty mechanical systems. 81207TN provides cost-effective, low-noise stable performance for standard working conditions, while 81207M delivers high-temperature resistance and anti-shock durability for harsh environments, fully covering mainstream industrial heavy-thrust application demands.
