81214 Thrust Ball Bearing | M / TN Types Available
The 81214 thrust ball bearing is a precision single-direction thrust ball bearing built for pure axial load support. Featuring high rigidity, low friction and stable axial positioning performance, it delivers steady and efficient operation for low to medium-speed industrial machinery. Available in 81214M and 81214TN cage variants, this bearing offers reliable, cost-effective thrust support for general mechanical transmission systems.
81214 M / TN Type Differences
81214M: Features a solid machined brass cage with high rigidity, superior heat resistance and strong impact resistance. It maintains ultra-low wear and stable operation during long continuous working cycles, ideal for heavy-load, high-temperature and harsh industrial conditions.
81214TN: Equipped with a lightweight nylon TN cage with low friction and quiet rotation. It provides excellent anti-fatigue performance and great cost efficiency, perfectly suited for medium-speed, clean and stable working environments with standard axial load demands.
Material Introduction
Bearing Steel (GCr15): Standard 81214 thrust ball bearings adopt high-quality GCr15 high-carbon chromium bearing steel. After professional heat treatment, steel balls and raceways gain high hardness, outstanding wear resistance and stable fatigue resistance, ensuring long-term precise operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81214 bearings deliver excellent rust-proof, anti-oxidation and weak corrosion resistance. They adapt well to humid, dusty and sanitary working scenarios, effectively avoiding premature bearing damage and extending service life.
Product Features
Stable single-direction pure axial load capacity. Accurate axial positioning with low running noise. Two cage structures fit diverse speed and load conditions. High hardness and wear resistance prolong service life. Compact structure saves installation space with high cost performance.
Application Scenarios
81214 thrust ball bearings are widely used in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81214M is suitable for heavy-load and harsh working environments; 81214TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
