Knuckle in A Car

Your front wheels rely on a strong component for steering and braking. We have been manufacturing forged automotive parts since 2011 and have supplied load-bearing components to Sany Heavy Industry, where precision and reliability are essential. This experience supports our expertise in high-strength structural parts.

This Knuckle in a Car is used on the front axle of passenger cars and light trucks. It transmits steering force and braking force while also absorbing road shocks during driving.

It is manufactured from 40Cr or 42CrMo forged steel. The process includes die forging followed by quenching and tempering. The hardness is controlled at HB 240–280, providing both strength and toughness for demanding operating conditions.

Our forging and machining processes are well established and strictly controlled.

The Knuckle in a Car features journal accuracy of IT7 grade. The mounting hole position tolerance is controlled within ≤0.05 mm.

It supports a load capacity of 2000–8000 kg, suitable for passenger cars and light trucks.

The surface is treated with black oxide and anti-rust oil for improved corrosion resistance. The operating temperature range is -40°C to 120°C, ensuring stable performance in various environments.

We provide more than a component-we deliver structural reliability for your steering system.

This Knuckle in a Car integrates multiple key functions: it supports the wheel hub bearing, carries the brake disc, and connects to the steering tie rod.

It is suitable for sedans, SUVs, and light trucks, and can be manufactured according to customer drawings and specifications.

The material is 40Cr or 42CrMo forged steel, ensuring high strength and long service life. With over a decade of experience since 2011, we are committed to delivering dependable steering components for safe vehicle operation.
