Bearings

Overview

Bearings are the core basic components of rotating machinery, widely used in slewing bearings, transmission systems and hydraulic systems of construction, mining and agricultural machinery and generator sets. Our range covers deep-groove ball, tapered roller, cylindrical roller, self-aligning roller and thrust bearings, with brands including SKF, NSK, NTN, ZWZ and LYC.

Features

  • Made of high-carbon chromium bearing steel, hardness HRC60-64, long wear life
  • Precision grades P0-P5 optional for different accuracy requirements
  • Seal options: open, metal shield (ZZ) and rubber seal (2RS)
  • High-temperature, corrosion-resistant and insulated bearings available for special conditions

Applications

Excavator slewing bearings, loader front/rear axles, road-roller vibration bearings, coal-machinery drum bearings, tractor gearboxes and generator main shafts.

Key Advantages

Complete brand coverage with genuine products; ample stock of common models; professional selection support to ensure correct matching.
