BUSH

BUSH – Precision-Machined Rotary Drilling Component for Bored Pile Machines

The BUSH is a fundamental component within the rotary drilling system of bored pile machines, ensuring accurate guidance, rotational control, and alignment of drilling tools under extreme loads. Designed to bear substantial axial and radial forces while maintaining tight tolerances, this cylindrical insert is the quiet workhorse behind high-performance drilling operations.

At 3GEN Export, we supply OEM-quality BUSH components engineered for dependable integration with a broad range of rotary rigs from leading manufacturers, including BAUER, LIEBHERR, SOILMEC, SANY, and XCMG.

What is a BUSH in Drilling Equipment?

In foundation drilling systems, the BUSH acts as a guiding and supporting insert typically mounted inside rotary heads, kelly bars, or casing tubes. It prevents misalignment, absorbs vibration, and reduces friction between rotating parts, thereby protecting structural components and prolonging the service life of the entire machine.

Machined to tight tolerances from durable steel or bronze alloys, this part is essential for maintaining stability and accuracy during vertical drilling operations—especially in deep or large-diameter boreholes.
