  • Affordable
  • Long-lasting
  • Incorporates advanced tuning techniques


  • Facilitates all engine functions directly or indirectly.
  • Has both spring-like tension and the quality to form a perfect circle when closed.
  • Effective in sealing the combustion gas,
  • Helps in controlling oil lubrication,
  • Successfully dissipate heat
  • minimize deterioration
  • increases engine durability and performance
  • preservers well under operational pressure.
  • Wide material range, including steel and cast iron.

Types of NDC Bearings

  1. Metal bearing
  2. Half bearing
  3. Resin Bushing and Plate

Metal bearing

An important part to support a connecting rod and a crankshaft to rotate in an engine for automobiles, motorcycles, construction machinery or ships.

Half bearing

Divided into two parts to cope with the complex shape of the installation point.

Resin Bushing and Plate

This type of bearing is widely used for various purposes in many places including: automotive automatic transmission, wiper, suspension, shafts for industrial machinery, electric and office automation equipment.


  • Good in abrasion resistance, load resistance, impact resistance, and heat resistance.
  • Half bearings which present excellent seizure resistance with the best load resistance.
  • Resin bearings are widely used for different types of sliding potions,and are required to be lead-free better consideration of the environment.


  • NDC Bearing can be used for places where the speed and the load would be a problem.
  • FR936 a type of Resin Bearings can be used for various purposes, such as: general industrial products, hydraulic products, home electric appliances, automobile parts, textile machines, packing machines.
  • It can be applied on complex shapes and various materials including: metals, rubbers, and plastics.
