Tapered roller bearing (English name: Tapered Roller Bearing) is a type of bearing that has conical roller – means large head and small head, which helps to transmit both effectively radial load and axial load (axial direction) At the same time. This is the ideal bearing for applications requiring high precision, continuous operation and high load bearing such as car wheel shafts, gearboxes, presses, construction machines, etc.
Highlights:
Double load bearing: Radial and axial loads in one direction
Detachable structure: Consists of inner ring (cone) and outer ring (cup), easy to install and replace
Effective anti-shaft vibration: Keeps the rotation system stable even under heavy loads
Optimized design for heavy engineering, automotive and transmission industries
Application:
Wheel axles for cars, trucks, trailers
Industrial gearboxes, differential boxes, gear shafts
Construction machinery, presses, crushers, turbines
Mining equipment, heavy construction machinery
