DAEWOO DH80 DH80-7 EXCAVATOR SLEWING SWING BEARING RING 640*900*83MM
Product Overview
Slewing Ring Bearing is a precision rotary component tailored for excavators. It connects the excavator’s upper structure to the lower chassis, enabling smooth 360° rotation. Made of high-strength 50Mn/42CrMo alloy steel via advanced forging and heat treatment, it offers excellent durability and load-bearing capacity for harsh construction sites. As an OEM replacement, it ensures seamless compatibility, reducing maintenance time and costs, and features integrated races, rolling elements and seals for dusty/muddy environments.
Key Specifications
Key Features
Perfect Model Compatibility: Customized- matching OEM specs for direct, modification-free installation.
Superior Load-Bearing Capacity: Single-row angular contact or three-ring design supports axial, radial and overturning loads for digging, lifting and swinging.
High-Strength & Durable: 50Mn/42CrMo alloy steel with heat treatment and precision grinding; surface anti-rust treatment enhances corrosion resistance.
Smooth & Precise Rotation: High-precision raceways and controlled clearances ensure low resistance, quiet operation and accurate positioning.
Robust Sealing: High-quality seals prevent soil, water and dust from entering, protecting internal components in harsh conditions.
Optional Internal Gear: Internal gear meshes perfectly with the excavator’s drive system, offering better strength and protection.
Easy Maintenance: Integrated lubrication channels and grease ports enable convenient maintenance to extend service life.
Typical Applications
Exclusively designed for the excavator, this slewing ring is critical for heavy-duty scenarios requiring smooth rotation and strong load-bearing. Main applications:
Construction & Earthmoving: Urban/rural projects (foundation digging, backfilling, trench digging) in tight or complex terrains.
Mining & Quarrying: Small-to-medium mining (ore extraction, gravel mining) with heavy loads, dust and vibration.
Infrastructure Maintenance: Municipal engineering, park renovation and road maintenance (debris cleaning, small-scale demolition).
Agricultural & Rural Construction: Farmland renovation, irrigation ditch digging and rural housing, adapting to harsh outdoor conditions.
Aftermarket Replacement: Direct OEM replacement for worn slewing rings, restoring excavator performance for maintenance and repair services.
