81213 Thrust Ball Bearing | M / TN Types Available
The 81213 thrust ball bearing is a high-precision single-direction thrust ball bearing designed for pure axial load operation. It features high rigidity, low friction and stable axial positioning, providing consistent and reliable support for low to medium-speed industrial machinery. Offered in 81213M and 81213TN cage types, this bearing is a durable and cost-effective solution for various mechanical transmission systems.
81213 M / TN Type Differences
81213M: Equipped with a solid machined brass cage with high structural rigidity, excellent heat resistance and strong impact resistance. It delivers low wear and stable performance during long-term continuous operation, ideal for heavy-load, high-temperature and harsh industrial working conditions.
81213TN: Adopts a lightweight nylon TN cage with a low friction coefficient and quiet rotation. It features great anti-fatigue performance and high cost performance, perfectly suitable for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81213 thrust ball bearings adopt premium GCr15 high-carbon chromium bearing steel. With professional heat treatment, steel balls and raceways achieve high hardness, outstanding wear resistance and stable fatigue resistance, ensuring long-term precise and stable operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81213 bearings provide 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 operating noise. Two cage designs meet diverse speed and load demands. Excellent hardness and wear resistance prolong service life. Compact structure saves installation space with high cost performance.
Application Scenarios
81213 thrust ball bearings are widely applied in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81213M suits heavy-load and harsh working environments; 81213TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
