81212 Thrust Ball Bearing | M / TN Types Available
The 81212 thrust ball bearing is a high-precision single-direction thrust ball bearing optimized for pure axial load operation. Featuring high rigidity, low friction and stable axial positioning, it delivers smooth and reliable performance for low to medium-speed industrial machinery. Available in 81212M and 81212TN cage types, this bearing offers durable and cost-effective thrust support for general mechanical transmission systems.
81212 M / TN Type Differences
81212M: Designed with a solid machined brass cage with high structural rigidity, superior heat resistance and strong impact resistance. It maintains low wear and stable output during long-term continuous operation, ideal for heavy-load, high-temperature and harsh industrial working conditions.
81212TN: Equipped with a lightweight nylon TN cage that provides low friction coefficient and quiet rotation. With excellent anti-fatigue performance and high cost performance, it is well suited for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81212 thrust ball bearings adopt premium GCr15 high-carbon chromium bearing steel. After professional heat treatment, the steel balls and raceways obtain high hardness, excellent wear resistance and stable fatigue resistance, ensuring long-term precise and stable operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81212 bearings feature outstanding rust-proof, anti-oxidation and weak corrosion resistance. They adapt perfectly to humid, dusty and sanitary working scenarios, effectively preventing premature bearing failure and extending service life.
Product Features
Reliable single-direction pure axial load capacity. High-precision axial positioning with low running noise. Two cage designs meet various speed and load conditions. Excellent hardness and wear resistance extend service life. Compact structure saves installation space with great cost performance.
Application Scenarios
81212 thrust ball bearings are widely used in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81212M is suitable for heavy-load and harsh working environments; 81212TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
