30208 Single Row Tapered Roller Bearing Separable Cone & Cup 40x80x19.75mm Automobile Truck Gearbox Equipment

The 30208 single row tapered roller bearing consists of separable inner cone, roller assembly and outer cup. It can simultaneously withstand combined radial and one-way axial loads, features high rigidity and stable bearing capacity, widely used in automobile wheel hubs, truck differentials, gearboxes and engineering machinery transmission parts.

• Separable cone and cup structure for easy independent installation and maintenance
• Tapered roller design bears heavy radial and unidirectional axial composite loads
• Optimized roller crowning reduces edge stress, lowers friction and running heat
• High-hardness quenched steel delivers strong wear resistance and long service life
• Standard universal size, fully interchangeable for vehicle and industrial equipment
• Custom precision grades and anti-rust surface treatment are available

This tapered roller bearing is widely applied in:

• Car and light truck front/rear wheel hub assemblies
• Automotive differential, transmission gearbox and drive shaft parts
• Small construction machinery, agricultural vehicle rotary transmission components
• General industrial equipment requiring simultaneous radial and axial load support

• 25+ years experience in tapered roller bearing production
• Exported to 50+ countries worldwide
