89311 Thrust Ball Bearing | M / TN Types Available
The 89311 thrust ball bearing is a heavy-duty single-direction thrust ball bearing designed for high pure axial load working conditions. Featuring high structural rigidity, strong load capacity and low-friction stable operation, it provides precise axial positioning and steady support for medium-speed heavy-duty industrial machinery. Offered in 89311M and 89311TN cage types, this bearing is a durable and cost-effective solution for heavy mechanical transmission systems.
89311 M / TN Type Differences
89311M: Equipped with a solid machined brass cage with high rigidity, excellent heat resistance and strong impact resistance. It effectively resists deformation under heavy loads and maintains stable continuous operation, making it ideal for heavy-load, high-temperature and harsh industrial environments.
89311TN: Adopts a lightweight reinforced nylon TN cage with low friction coefficient and quiet rotation performance. It delivers reliable anti-fatigue properties and high cost efficiency, perfectly suited for medium-speed, clean working environments with heavy axial load demands.
Material Introduction
Bearing Steel (GCr15): Standard 89311 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 stable operation under continuous heavy axial loads.
Stainless Steel (Optional): Custom stainless steel 89311 bearings feature 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 heavy axial load capacity. High-precision axial positioning with low running noise. Dual cage designs meet diverse heavy-duty working requirements. High hardness and deformation resistance prolong service life. Compact structure with excellent cost performance.
Application Scenarios
89311 thrust ball bearings are widely used in heavy-duty hydraulic equipment, industrial gearboxes, mining machinery, construction machinery and heavy mechanical transmission systems. 89311M suits heavy-load and harsh working conditions; 89311TN fits medium-speed, low-noise and cost-sensitive heavy equipment. Stainless steel versions apply to humid and sanitary industrial scenarios.
