81211 Thrust Ball Bearing | M / TN Types Available
The 81211 thrust ball bearing is a precision single-direction thrust ball bearing designed to withstand pure axial loads. With high structural rigidity, low friction and stable axial positioning capability, it delivers steady operation for low and medium-speed industrial machinery. Available in 81211M and 81211TN cage types, this bearing is a durable and cost-effective solution for various mechanical transmission systems.
81211 M / TN Type Differences
81211M: Equipped with a solid machined brass cage featuring high rigidity, excellent heat resistance and strong impact resistance. It runs stably with minimal wear during long continuous operation, ideal for heavy-load, high-temperature and harsh industrial working conditions.
81211TN: Adopts a lightweight nylon TN cage with low friction and quiet rotation performance. It provides reliable anti-fatigue properties and great cost performance, perfectly suited for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81211 thrust ball bearings adopt premium GCr15 high-carbon chromium bearing steel. Through strict heat treatment, steel balls and raceways gain 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 81211 bearings feature excellent rust-proof, anti-oxidation and weak corrosion resistance. They adapt well to humid, dusty and sanitary working scenarios, effectively avoiding 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 structures meet different speed and load demands. High hardness and wear resistance prolong service life. Compact structure saves installation space with high cost performance.
Application Scenarios
81211 thrust ball bearings are widely applied in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81211M fits heavy-load and harsh working environments; 81211TN suits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
