Test

We develop and supply customized special-purpose test equipment, delivering solutions optimized for each customer’s specific objectives. At KNR Systems we strive to be a trusted partner in research and development, supporting innovation through tailored engineering and technical expertise.

Robot

KNR Systems provides hydraulic robotic arms, standard mobile robots (robot arm platforms), hydraulic components, and robotic solutions based on its unrivaled hydraulic robot technology.

Bearing System

Bearings are critical components that reduce friction and enable smooth rotation during vehicle operation, significantly influencing ride quality and safety. To precisely evaluate their performance, durability, and reliability, a variety of tests—such as load testing, vibration analysis, friction coefficient measurement, and thermal variation assessment—are required. KNR Systems bearing testing equipment ensures accurate and repeatable evaluations even under extreme conditions. Its flagship solution, the Mud & Salt Water Splash Testing System, is specifically designed to replicate real road conditions by exposing wheel bearings to mud and saltwater environments, enabling comprehensive durability and performance testing across a wide range of scenarios.

Mud & Salt Water Splash Testing System

The Wheel Bearing Mud/Saline Splash Test Equipment is designed to simulate load and rotation conditions equivalent to those of an actual vehicle on wheel bearings. It evaluates the long-term reliability of the bearing's sealing performance by exposing it to mud and saline splashes under realistic operating conditions.
