81204 Thrust Ball Bearing | M / TN Types Available
The 81204 thrust ball bearing is a high-precision single-direction thrust bearing designed for pure axial load bearing. Featuring high rigidity, stable structure and low-friction operation, it delivers accurate axial positioning for low and medium-speed industrial machinery. Available in 81204M and 81204TN cage types, this bearing provides reliable and cost-effective thrust support for various mechanical transmission systems.
81204 M / TN Type Differences
81204M: Equipped with a solid machined brass cage with high structural rigidity, excellent heat resistance and strong impact resistance. It maintains low wear and stable operation during long-term continuous operation, ideal for heavy-load, high-temperature and harsh industrial working conditions.
81204TN: Adopts a lightweight nylon TN cage with a low friction coefficient and quiet rotation performance. It offers outstanding anti-fatigue ability and high cost performance, perfectly suited for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81204 thrust ball bearings adopt premium GCr15 high-carbon chromium bearing steel. After professional heat treatment, the steel balls and raceways achieve 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 81204 bearings feature reliable 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 great cost performance.
Application Scenarios
81204 thrust ball bearings are widely used in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81204M suits heavy-load and harsh working environments; 81204TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
