89310 Thrust Ball Bearing | M / TN Types Available
The 89310 thrust ball bearing is a heavy-duty single-direction thrust ball bearing optimized for high pure axial load operation. It delivers high rigidity, extreme load capacity and low-friction stability, offering accurate axial positioning and durable support for medium-speed heavy-duty industrial machinery. Available in 89310M and 89310TN cage types, this bearing serves as a reliable and cost-effective solution for heavy mechanical transmission systems.
89310 M / TN Type Differences
89310M: Features a solid machined brass cage with superior structural rigidity, outstanding heat resistance and strong impact tolerance. It resists deformation under extreme heavy loads and ensures stable long-term continuous operation, ideal for heavy-load, high-temperature and harsh industrial working environments.
89310TN: Adopts a lightweight reinforced nylon TN cage with low friction coefficient and quiet rotation. It provides stable anti-fatigue performance and excellent cost efficiency, perfectly suited for medium-speed, clean working conditions with heavy axial load requirements.
Material Introduction
Bearing Steel (GCr15): Standard 89310 thrust ball bearings are made of premium GCr15 high-carbon chromium bearing steel. Professional heat treatment endows raceways and steel balls with high hardness, exceptional wear resistance and stable fatigue resistance, supporting long-term stable operation under continuous heavy axial loads.
Stainless Steel (Optional): Custom stainless steel 89310 bearings offer reliable 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 service life.
Product Features
Powerful single-direction heavy axial load capacity. High-precision axial positioning with low operating noise. Dual cage designs fit diverse heavy-duty working demands. Excellent hardness and deformation resistance extend service life. Compact layout with superior cost performance.
Application Scenarios
89310 thrust ball bearings are widely applied in heavy-duty hydraulic equipment, industrial gearboxes, mining machinery, construction machinery and heavy mechanical transmission systems. 89310M is suitable for heavy-load and harsh working conditions; 89310TN matches medium-speed, low-noise and cost-sensitive heavy equipment. Stainless steel versions apply to humid and sanitary industrial scenarios.
