Business Overview
Another core business of KATEM is the localization of powertrain components for Commercial
Vehicles,
a sector still heavily dependent on imports. Commercial Vehicles cover all land vehicles except
passenger cars,
including buses, trucks, off-road RVs, construction equipment, agricultural machinery, defense and
special-purpose vehicles.
The key component applied across these vehicles is the drive shaft, which transfers engine power via
the propeller shaft
and differential gear box to the front and rear wheels.
Key Technologies & Achievements
- Axle: standard axles and independent suspension type
- Powertrain parts: propeller shafts, drive shafts, wheel hubs
- Brake parts: forged steel, cast steel, and cast iron brake discs
- Axle-type brake discs
- Wheel-type brake discs
- Axle- and wheel-type brake calipers
- Experience in full process of Double Cardan drive shaft design, production, and reliability testing
- Localization and import substitution of Commercial Vehicle powertrain and brake parts
- Development and supply of cast/forged steel brake discs for high-speed rail to KORAIL
- Global market readiness with internationally certified quality systems
Vision
Building on our expertise in Commercial Vehicle powertrain and brake parts,
KATEM aims to maximize import substitution in domestic and overseas markets,
and strengthen global competitiveness through international quality certification,
positioning itself as a leading specialist in this field.
a sector that has long relied on imports. Commercial Vehicles include buses, trucks, off-road RVs,
construction equipment, agricultural machinery, defense, and special-purpose vehicles, even extending to railway vehicles.
A key component applied across these vehicles is the drive shaft, which transfers engine torque
from the propeller shaft through the differential gear box to the wheels.
While such drive shafts, particularly the Double Cardan type, have traditionally been fully imported due to
technical and market limitations, KATEM has accumulated full-cycle capabilities in design, manufacturing,
and reliability testing through continuous R&D efforts.
Alongside, we have advanced brake technologies, including discs and calipers, to grow into a specialist in this field.
Notably, KATEM has successfully localized cast iron brake discs for Commercial Vehicles
and developed cast and forged steel brake discs for high-speed rail, now supplied to KORAIL.
These achievements, combined with ongoing certification to international quality standards,
reinforce our commitment to becoming a global leader in Commercial Vehicle powertrain and brake systems.
