Product Description

Product Name: RU297G RU297X Cross Roller Excavator Slewing Bearing, Heavy-Duty Slewing Ring

RU297G/RU297X are heavy-duty crossed roller bearings specifically designed for excavator and construction machinery turntables. Adopting an integrated inner and outer ring structure with pre-drilled mounting holes, they can be directly bolted without additional flanges or supports, ensuring easy installation and strong adaptability to installation errors. Featuring a 90° crossed cylindrical roller layout, a single bearing can simultaneously bear radial load, axial load and large overturning moment, with rigidity 3-4 times higher than that of traditional bearing sets, effectively ensuring the smooth rotation of excavators and resisting impact loads during digging operations.

Core Parameters:
  • Dimensions (mm): ID 210 × OD 380 × Width 40
  • Model Difference: RU297G (Standard type, high rigidity, suitable for general working conditions); RU297X (Reinforced type, higher precision, suitable for heavy load and impact working conditions)
  • Material: GCr15 bearing steel, hardened by quenching, with excellent wear resistance and impact resistance
  • Precision Grade: P5/P4 (P5 grade is commonly used for construction machinery)
  • Load Ratings: Dynamic Load Cr 156 kN, Static Load Cor 281 kN
  • Weight: Approx. 21.3 kg
  • Seal Options: Open type (X), Double-sided NBR seals (UU), dust and water proof, suitable for harsh dust and muddy environments on construction sites
Typical Applications
  • Excavator slewing systems
  • Construction machinery
  • Industrial robots
  • Automation rotary platforms
  • Lifting equipment
  • CNC rotary tables
  • Heavy-duty rotating machinery
