81210 Thrust Ball Bearing | M / TN Types Available
The 81210 thrust ball bearing is a high-precision single-direction thrust ball bearing engineered for pure axial loads. Featuring high rigidity, low friction and stable axial positioning, it delivers reliable and consistent performance for low to medium-speed industrial machinery. Offered in 81210M and 81210TN cage types, this bearing provides durable, cost-effective thrust support for a wide range of mechanical transmission systems.
81210 M / TN Type Differences
81210M: Features a solid machined brass cage with high structural rigidity, outstanding heat resistance and strong impact tolerance. It ensures low wear and stable operation during long-term continuous running, making it ideal for heavy-load, high-temperature and harsh industrial working conditions.
81210TN: Adopts a lightweight nylon TN cage with a low friction coefficient and quiet rotation. It provides excellent anti-fatigue performance and high cost efficiency, perfectly suited for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81210 thrust ball bearings are manufactured with premium GCr15 high-carbon chromium bearing steel. After professional heat treatment, the steel balls and raceways achieve high hardness, superior wear resistance and stable fatigue resistance, supporting long-term precise operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81210 bearings offer excellent rust-proof, anti-oxidation and weak corrosion resistance. They adapt seamlessly to humid, dusty and sanitary working scenarios, preventing premature bearing failure and extending overall service life.
Product Features
Reliable single-direction pure axial load capacity. High-precision axial positioning with low operating noise. Two cage designs meet diverse speed and load demands. Superior hardness and wear resistance extend service life. Compact space-saving structure with excellent cost performance.
Application Scenarios
81210 thrust ball bearings are widely used in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81210M suits heavy-load and harsh working environments; 81210TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
