81102Cylindrical Roller Thrust Bearings

81102 Thrust Cylindrical Roller Bearing | 81102TN And 81102M Cage And Application

The 81102 is a standard single-direction thrust cylindrical roller bearing with standard dimensions of 15×28×9mm. Designed exclusively for unidirectional heavy axial loads, this bearing features ultra-high rigidity, minimal deformation and stable low-speed operation. It effectively limits shaft axial displacement, absorbs continuous thrust pressure and maintains precise mechanical positioning. Compared with other thrust bearings, the 81102 delivers lower friction loss and stronger load capacity, making it ideal for heavy-thrust, low-speed industrial mechanical systems. The series offers two mainstream configurations: 81102TN with nylon cage and 81102M with solid brass cage, catering to general and harsh industrial working conditions.

81102TN Bearing (Nylon PA66 Cage)

81102TN adopts a high-strength injection-molded PA66 nylon cage, serving as the standard economical model for regular working environments. The lightweight nylon cage features excellent toughness, low friction coefficient and reliable anti-fatigue performance. It ensures precise and flexible cylindrical roller circulation, effectively reducing running noise and frictional heat during long-term cyclic operation. With outstanding lubricity and corrosion resistance, the nylon structure avoids rigid abrasion and extends grease service life. Suited for clean, medium-temperature and standard-load working scenarios, 81102TN provides stable consistent performance and optimal cost efficiency for conventional precision thrust machinery.

81102M Bearing (Solid Brass Cage)

81102M is fitted with a one-piece precision machined solid brass cage, the premium heavy-duty version for extreme working conditions. The high-rigidity brass cage boasts superior high-temperature resistance, structural stability and impact resistance, far exceeding the performance of nylon cages. It maintains accurate roller spacing and structural integrity under high temperatures, heavy instantaneous thrust loads and long-duration uninterrupted operation. This effectively prevents roller skew and structural deformation, greatly improving overall bearing durability and operational stability. 81102M is dedicated to critical core equipment that requires zero-failure operation in harsh, high-load and high-temperature environments.

Bearing Material And Structural Advantages

All 81102 series bearings are manufactured from high-purity chrome bearing steel. Through integral quenching and ultra-precision grinding, the raceways and cylindrical rollers achieve high surface hardness, exceptional wear resistance and stable mechanical properties. The flat raceway design ensures uniform force distribution, eliminating local stress concentration. Its compact and high-rigidity structure supports extreme axial loads with minimal elastic deformation, guaranteeing accurate axial positioning and stable long-term operation for mechanical shafts.

Industrial Applications

81102 thrust cylindrical roller bearings are widely used for unidirectional axial load support and shaft positioning. 81102TN is commonly applied in precision instruments, small reduction gearboxes, general automated machinery and light industrial transmission equipment. 81102M is ideal for high-temperature processing equipment, hydraulic systems, mining auxiliary machinery and heavy-load precision transmission systems requiring high stability and extended service life.

Product Summary: The 81102 bearing provides reliable high-rigidity axial load capacity for precision mechanical systems. 81102TN offers cost-effective, low-noise stable performance for standard conditions, while 81102M delivers high-temperature and anti-shock durability for harsh scenarios, fully covering mainstream precision heavy-thrust industrial application demands.
