81217 Thrust Ball Bearing | M / TN Types Available
The 81217 thrust ball bearing is a precision single-direction thrust ball bearing designed for pure axial loads. It features high rigidity, low friction and stable axial positioning, ensuring stable and efficient operation for low to medium-speed industrial equipment. Available in 81217M and 81217TN cage types, this bearing provides reliable and cost-effective axial thrust support for various mechanical transmission systems.
81217 M / TN Type Differences
81217M: Adopts a solid machined brass cage with high structural rigidity, excellent heat resistance and strong impact resistance. It runs steadily with low wear during long-term continuous operation, making it suitable for heavy-load, high-temperature and harsh industrial working conditions.
81217TN: Equipped with a lightweight nylon TN cage featuring low friction coefficient and quiet rotation performance. It offers great anti-fatigue ability and high cost performance, ideal for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81217 thrust ball bearings are manufactured from premium GCr15 high-carbon chromium bearing steel. After professional heat treatment, steel balls and raceways achieve high hardness, outstanding wear resistance and stable fatigue resistance, supporting long-term precise and stable operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81217 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 diverse speed and load demands. High hardness and wear resistance prolong service life. Compact structure saves installation space with excellent cost performance.
Application Scenarios
81217 thrust ball bearings are widely applied in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81217M suits heavy-load and harsh working environments; 81217TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
