81113 Thrust Ball Bearing | M / TN Types Available
The 81113 thrust ball bearing is a high-precision single-direction thrust ball bearing designed for pure axial loads. It features a compact structure, high rigidity and low friction, delivering accurate axial positioning and stable operation for low to medium-speed industrial machinery. Available in 81113M and 81113TN cage types, this bearing provides durable and cost-effective thrust support for various mechanical transmission systems.
81113 M / TN Type Differences
81113M: Equipped with a solid machined brass cage with high structural rigidity, excellent heat resistance and strong impact resistance. It maintains ultra-low wear and stable performance during long-term continuous operation, ideal for heavy-load, high-temperature and harsh industrial working conditions.
81113TN: Adopts a lightweight nylon TN cage with a low friction coefficient and quiet rotation. It offers superior anti-fatigue performance and excellent cost performance, perfectly suited for medium-speed, clean and stable working environments with standard axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 81113 thrust ball bearings adopt 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, ensuring long-term precise and stable operation under continuous axial loads.
Stainless Steel (Optional): Custom stainless steel 81113 bearings feature excellent rust-proof, anti-oxidation and weak corrosion resistance. They adapt perfectly to humid, dusty and sanitary working scenarios, effectively preventing premature bearing failure and extending overall service life.
Product Features
Reliable single-direction pure axial load capacity. High-precision axial positioning with low operating noise. Two cage designs meet diverse speed and load demands. Excellent hardness and wear resistance extend service life. Compact structure saves installation space with high cost performance.
Application Scenarios
81113 thrust ball bearings are widely used in hydraulic systems, industrial gearboxes, ventilation fans, textile machinery, printing equipment and general mechanical transmissions. 81113M suits heavy-load and harsh working environments; 81113TN fits medium-speed, low-noise and cost-sensitive equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
