81209 Thrust Ball Bearing | M / TN Types Available
The 81209 thrust ball bearing is a high-precision single-direction thrust ball bearing designed for pure axial loads. It features high rigidity, low friction and stable axial positioning, delivering consistent performance for low and medium-speed industrial machinery. Available in 81209M and 81209TN cage types, this bearing provides durable and cost-effective thrust support for various mechanical transmission systems.
81209 M / TN Type Differences
81209M: Built with a solid machined brass cage featuring high structural rigidity, excellent heat resistance and strong impact resistance. It maintains low wear and stable operation during long continuous running, ideal for heavy-load, high-temperature and harsh industrial working conditions.
81209TN: Equipped with a lightweight nylon TN cage with low friction coefficient and quiet rotation performance. It offers reliable anti-fatigue properties and excellent cost performance, perfect for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81209 thrust ball bearings adopt premium GCr15 high-carbon chromium bearing steel. With professional heat treatment, steel balls and raceways achieve high hardness, superior wear resistance and stable fatigue resistance, ensuring long-term precise and stable operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81209 bearings deliver excellent rust-proof, anti-oxidation and weak corrosion resistance. They adapt well to humid, dusty and sanitary working scenarios, effectively preventing premature bearing failure and extending service life.
Product Features
Stable single-direction pure axial load capacity. High-precision axial positioning with low running noise. Two cage designs meet different speed and load demands. Excellent hardness and wear resistance extend service life. Compact structure saves installation space with high cost performance.
Application Scenarios
81209 thrust ball bearings are widely applied in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81209M suits heavy-load and harsh working environments; 81209TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
