JP8049/JP8010 Metric Single Row Tapered Roller Bearing 80x125x24mm Cone Cup Assembly

JP8049/JP8010 is standard metric single-row separable tapered roller bearing set, composed of inner cone JP8049 and outer cup JP8010. Overall dimensions: 80mm inner bore × 125mm outer diameter × 24mm total assembly width.

This bearing simultaneously bears heavy radial load and unidirectional axial thrust load. Separable cone and cup design allows flexible preload adjustment during assembly to match different equipment clearance and rigidity demands. All rolling components adopt fully quenched GCr15 bearing steel, with precision super-ground tapered raceways and rollers to form uniform contact stress distribution, stable operation under shock, vibration and intermittent heavy impact loads. Widely applied to medium & heavy truck wheel hubs, metallurgical auxiliary transmission equipment, construction machinery, heavy-duty gear reducers, agricultural large tractors and off-road vehicles with high composite radial-axial load requirements.

Mounting shoulder dimension drawings, preload adjustment operation guides and load performance test reports can be provided on customer demand.

• Separable cone and cup integrated set, easy independent disassembly, installation and on-site preload adjustment, greatly reducing heavy vehicle and industrial equipment maintenance difficulty.
• Excellent high composite load bearing capacity, stable operation under heavy radial load and unidirectional axial thrust, outstanding anti-shock performance for metallurgy, construction and heavy vehicle working conditions.
• Ultra-precision grinding process for raceways and tapered rollers, smooth contact surface, low running noise, uniform contact area to avoid local overheating and premature raceway peeling.
• High hardness fully quenched GCr15 steel, stable internal metallographic structure, superior contact fatigue resistance and wear resistance, extending service life under long-term cyclic heavy impact load.
• Reinforced stamped steel cage, firmly fix each tapered roller position, prevent roller deflection and dislocation under large vibration and heavy impact.
• Standard metric interchangeable size, fully compatible with global same model bearing sets, direct replacement without modifying shaft and housing installation structure.
• Strict taper angle tolerance control, consistent contact pattern after installation, effectively reduce friction heat generation and abnormal wear during continuous heavy load operation.
• Multiple customizable options: P0/P6 precision grade, anti-rust surface coating, OEM laser marking on cone and cup, neutral export anti-rust carton packaging, high temperature resistant special grease filling.
