KZ Bearings: Powering Performance in Construction Machinery

Built for Heavy-Duty Applications

KZ Bearings, engineered by KG Bearing India LLP, are designed to meet the rigorous needs of construction machines such as:

• Excavators
• Loaders
• Cranes
• Bulldozers
• Concrete mixers
• Road rollers

These machines require components that can handle heavy radial and axial loads, shock impacts, and continuous movement. KZ Bearings are built with high-grade steel, advanced heat treatment, and precision engineering—ensuring smooth operation and a longer lifespan, even in tough jobsite conditions.

Here’s a breakdown of how each type of KZ bearing is used in construction machinery applications:

KZ Tapered Roller Bearings – For Wheels and Gearboxes

• How Used:
  Tapered roller bearings are ideal for applications involving combined radial and axial loads, such as wheel hubs and construction gearboxes.
• Example:
  In a bulldozer or loader, these bearings support the wheels, helping them rotate smoothly under the machine’s heavy weight. In gearboxes, they maintain gear alignment under load, ensuring power is transferred efficiently.

KZ Spherical Roller Bearings – For High-Load Misaligned Joints

• How Used:
  These bearings are designed to handle misalignment and very high radial loads, making them ideal for pivoting parts in tough environments.
• Example:
  In excavator arms and crane joints, where structural flexing occurs during operation, spherical roller bearings maintain smooth motion without being affected by misalignment or deformation.

KZ Cylindrical Roller Bearings – For Heavy-Duty Transmissions

• How Used:
  These bearings carry high radial loads and are suitable for high-speed and high-precision applications.
• Example:
  In road rollers or large mixers, cylindrical roller bearings are used in motors and transmission shafts to maintain reliable power transfer, even under constant vibration and stress.

KZ Spherical Roller Thrust Bearings – For Vertical Shafts and Crane Booms

• How Used:
  Thrust bearings are specifically designed to handle axial loads (loads parallel to the shaft).
• Example:
  In crane slewing rings, these bearings allow the boom to rotate smoothly under load. In vertical lifting systems, they manage the downward force as materials are raised or lowered.
