89305 Thrust Ball Bearing | M / TN Types Available
The 89305 thrust ball bearing is a heavy-duty single-direction thrust ball bearing engineered for high pure axial load applications. It features high rigidity, strong load capacity and low-friction stable operation, delivering accurate axial positioning for medium-speed heavy-duty industrial machinery. Offered in 89305M and 89305TN cage types, this bearing provides durable, cost-effective thrust support for heavy mechanical transmission systems.
89305 M / TN Type Differences
89305M: Features a solid machined brass cage with high rigidity, outstanding heat resistance and strong impact resistance. It effectively resists deformation under heavy loads and runs stably during long-term continuous operation, ideal for heavy-load, high-temperature and harsh industrial working conditions.
89305TN: Adopts a lightweight reinforced nylon TN cage with low friction coefficient and quiet rotation. It delivers reliable anti-fatigue performance and excellent cost efficiency, perfectly suited for medium-speed, clean working environments with standard heavy axial load demands.
Material Introduction
Bearing Steel (GCr15): Standard 89305 thrust ball bearings are manufactured from premium GCr15 high-carbon chromium bearing steel. With professional heat treatment, raceways and steel balls gain high hardness, superior wear resistance and stable fatigue resistance, ensuring long-term stable operation under continuous heavy axial loads.
Stainless Steel (Optional): Custom stainless steel 89305 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
Superior single-direction heavy axial load capacity. High-precision axial positioning with low operating noise. Two cage designs meet diverse heavy-duty working conditions. High hardness and deformation resistance ensure long service life. Compact structure with excellent cost performance.
Application Scenarios
89305 thrust ball bearings are widely applied in heavy-duty hydraulic equipment, industrial gearboxes, mining machinery, construction machinery and heavy mechanical transmission systems. 89305M suits heavy-load and harsh working environments; 89305TN fits medium-speed, low-noise and cost-sensitive heavy equipment. Stainless steel versions apply to humid and sanitary industrial conditions.
