Advantage

  • High Precision Dimension: The carbon steel plate has excellent processing technology good molding and easy welding. Thickened material, stable performance, and high hardness, not easy to rust.
  • Low Friction: Low dissipation factor. More durable than most ordinary domestic bearings. Lower operating costs​
  • Life Is Long: High-quality steel through strict quality inspection, quality control layer-by-layer detection, and reliable quality, long service life.
  • Customization: Drawings and samples can be processed and customized. Conventional large-scale spot, non-standard customization.
