81115 Thrust Ball Bearing | M / TN Types Available
The 81115 thrust ball bearing is a high-precision single-direction thrust ball bearing designed for pure axial load support. Featuring high structural rigidity, compact layout and low-friction operation, it provides precise axial positioning and consistent stability for low and medium-speed industrial machinery. Offered in 81115M and 81115TN cage variants, this bearing delivers durable and cost-effective thrust support for general mechanical transmission systems.
81115 M / TN Type Differences
81115M: Equipped with a solid machined brass cage with high rigidity, excellent heat resistance and strong impact resistance. It maintains minimal wear and stable performance during long-term continuous operation, ideal for heavy-load, high-temperature and harsh industrial working conditions.
81115TN: Adopts a lightweight nylon TN cage with a low friction coefficient and quiet rotation. It features reliable anti-fatigue performance and great cost efficiency, perfectly suited for medium-speed, clean and stable working environments with standard axial load demands.
Material Introduction
Bearing Steel (GCr15): Standard 81115 thrust ball bearings adopt premium GCr15 high-carbon chromium bearing steel. Through professional heat treatment, steel balls and raceways achieve high hardness, outstanding wear resistance and stable fatigue resistance, ensuring long-term precise operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81115 bearings provide excellent rust-proof, anti-oxidation and weak corrosion resistance. They adapt well to humid, dusty and sanitary working scenarios, preventing premature bearing failure and extending overall service life.
Product Features
Reliable single-direction pure axial load capacity. Accurate axial positioning with low operating noise. Two cage designs meet diverse speed and load requirements. High hardness and wear resistance extend service life. Compact space-saving structure with excellent cost performance.
Application Scenarios
81115 thrust ball bearings are widely used in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81115M suits heavy-load and harsh working environments; 81115TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
