81205 Thrust Ball Bearing | M / TN Types Available
The 81205 thrust ball bearing is a precision single-direction thrust ball bearing built to handle pure axial loads. Featuring high structural rigidity, stable performance and low friction operation, it ensures accurate axial positioning for low and medium-speed industrial machinery. Supplied in 81205M and 81205TN cage types, this bearing delivers reliable, cost-effective thrust support for general mechanical transmission systems.
81205 M / TN Type Differences
81205M: Features a solid machined brass cage with high rigidity, outstanding heat resistance and strong impact resistance. It runs steadily with low wear during long continuous operation, making it ideal for heavy-load, high-temperature and harsh industrial working conditions.
81205TN: Equipped with a lightweight nylon TN cage featuring low friction and quiet rotation. It provides excellent anti-fatigue performance and superior cost performance, perfectly suited for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81205 thrust ball bearings adopt high-quality GCr15 high-carbon chromium bearing steel. With precise heat treatment, the steel balls and raceways achieve high hardness, excellent wear resistance and stable fatigue resistance, supporting long-term stable and precise operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81205 bearings offer excellent rust-proof, anti-oxidation and weak corrosion resistance. They adapt perfectly 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. High-precision axial positioning with low running noise. Two cage structures fit different speed and load conditions. High hardness and wear resistance extend service life. Compact structure saves installation space with high cost performance.
Application Scenarios
81205 thrust ball bearings are widely applied in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81205M is suitable for heavy-load and harsh working environments; 81205TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
