89309 Thrust Ball Bearing | M / TN Types Available
The 89309 thrust ball bearing is a heavy-duty single-direction thrust ball bearing designed for high pure axial load working conditions. Featuring high rigidity, large load capacity and low-friction stable operation, it provides precise axial positioning and reliable support for medium-speed heavy-duty industrial machinery. Available in 89309M and 89309TN cage types, this bearing is a durable and cost-effective solution for heavy mechanical transmission systems.
89309 M / TN Type Differences
89309M: Equipped with a solid machined brass cage with high structural rigidity, excellent heat resistance and strong impact resistance. It effectively prevents deformation under heavy loads and maintains stable long-term continuous operation, ideal for heavy-load, high-temperature and harsh industrial environments.
89309TN: Adopts lightweight reinforced nylon TN cage with low friction coefficient and quiet rotation performance. It offers stable anti-fatigue ability and outstanding cost performance, perfectly suitable for medium-speed, clean working scenarios with heavy axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 89309 thrust ball bearings adopt high-quality GCr15 high-carbon chromium bearing steel. After professional heat treatment, raceways and steel balls obtain high hardness, excellent wear resistance and stable fatigue resistance, supporting long-term stable operation under continuous heavy axial loads.
Stainless Steel (Optional): Custom stainless steel 89309 bearings deliver great rust-proof, anti-oxidation and weak corrosion resistance. They adapt well to humid, dusty and sanitary working environments, avoiding premature bearing damage and extending service life.
Product Features
Excellent single-direction heavy axial load capacity. High-precision axial positioning with low running noise. Two cage designs meet different heavy-duty working demands. High hardness and deformation resistance prolong service life. Compact structure with high cost performance.
Application Scenarios
89309 thrust ball bearings are widely used in heavy-duty hydraulic equipment, industrial gearboxes, mining machinery, construction machinery and heavy mechanical transmission systems. 89309M applies to heavy-load and harsh working conditions; 89309TN fits medium-speed, low-noise and cost-sensitive heavy equipment. Stainless steel versions are suitable for humid and sanitary industrial scenarios.
