Overview

Covering mainstream models compatible with 6 tons, 20 tons and 30 tons excavators, this series adopts high-standard raw material control and precision machining technology, withstanding impact load, frequent forward and reverse rotation and harsh outdoor working conditions of earthmoving operations. It is an essential core component for construction machinery manufacturers, earthmoving equipment fleet operators and engineering procurement specialists.

Technical Specifications & Dimensional Parameters

Key Features & Performance Advantages

High-purity Raw Material & Stable Microstructure

The 013 series excavator slewing bearing adopts strict high-standard raw material composition control, obtains a stable and uniform microstructure after forging and heat treatment, greatly improving the fatigue resistance and wear resistance of the raceway.

Full-process Precision Control & Quality Monitoring

We realize online measurement of hardened layer depth and raceway profile during machining, strictly control internal clearance between 0.04-0.25mm, axial runout ≤0.12mm, and mounting surface flatness ≤0.15mm, ensuring the precision consistency of each product.

Specialized Sealing System for Excavator Working Conditions

Equipped with a dedicated sealing strip for excavator slewing bearings, it can effectively block dust, sediment, rainwater and other impurities on construction sites, prevent grease leakage, and adapt to the harsh outdoor construction environment of earthmoving operations.

Heavy Load Impact Resistance & Long Service Life

Optimized raceway design and heat treatment process enable the product to withstand long-term heavy load and frequent impact load, reduce wear rate during high-frequency rotation, and significantly extend the maintenance cycle and service life.

Applications & Compatible Equipment

This series is mainly suitable for 6 tons, 20 tons, 30 tons hydraulic crawler excavators and wheeled excavators, widely used in earthmoving engineering, municipal construction, garden engineering, mining excavation, water conservancy construction and other scenarios. It can also be compatible with other construction machinery with the same tonnage and similar rotary structure requirements.

Installation, Operation & Maintenance Guidelines

Installation Specifications

Before installation, check the integrity of the raceway and sealing parts, calibrate the flatness of the equipment mounting surface, and tighten mounting bolts in diagonal order with specified torque to avoid uneven stress.

Operation & Maintenance Rules

During operation, avoid long-term overload operation and frequent violent impact rotation, stop for inspection immediately if abnormal noise, jamming or excessive temperature rise occurs during rotation. Clean the sealing contact surface regularly, add special grease for construction machinery slewing bearings according to the usage cycle, check bolt tightening torque, and regularly detect raceway wear and internal clearance changes.

Customization & Bulk Procurement Solutions

We provide exclusive customization and bulk procurement solutions for construction machinery manufacturers and engineering procurement teams, including non-standard size customization, material upgrading for special working conditions, sealing system optimization and personalized structural modification. For bulk procurement, we provide stable mass production delivery cycles, exclusive pricing, full-batch quality certification and dedicated technical docking services.

FAQs About 013 Series Excavator Slewing Circle
