81215 Thrust Ball Bearing | M / TN Types Available
The 81215 thrust ball bearing is a high-precision single-direction thrust ball bearing designed for pure axial loads. Featuring high rigidity, low friction and stable axial positioning, it ensures smooth, stable operation for low and medium-speed industrial machinery. Available in 81215M and 81215TN cage types, this bearing provides reliable and cost-effective thrust support for various mechanical transmission systems.
81215 M / TN Type Differences
81215M: Adopts a solid machined brass cage with high structural rigidity, excellent heat resistance and strong impact resistance. It delivers low wear and consistent stability during long continuous operation, ideal for heavy-load, high-temperature and harsh industrial working conditions.
81215TN: Equipped with a lightweight nylon TN cage featuring low friction and quiet rotation. It offers great anti-fatigue performance 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 81215 thrust ball bearings are made of premium GCr15 high-carbon chromium bearing steel. Professional heat treatment endows steel balls and raceways with high hardness, superior wear resistance and stable fatigue resistance, supporting long-term precise operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81215 bearings feature excellent 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. Outstanding hardness and wear resistance extend service life. Compact structure saves installation space with excellent cost performance.
Application Scenarios
81215 thrust ball bearings are widely applied in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81215M suits heavy-load and harsh working environments; 81215TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
