V43 Tooth Seat ESCO Style 35-45 Ton Excavator Bucket Tooth Seat Double Groove Weld-on Type Compatible with V43SYL Tooth Tip

The V43 tooth holder is an important accessory for construction machinery such as excavators and loaders. Below is a detailed introduction to its features, applications and material characteristics:
 

Product Features

• Unique Structural Design: Adopts the Super V vertical locking system, such as the V43PN special elastic pin. The locking surface can be automatically renewed with replacement, offering strong fatigue resistance. Some models feature a twin-tip or streamlined pointed design — for example, the V43AD tooth holder has a pointed tip that enhances penetration, making it suitable for rock excavation.
• Outstanding Performance Advantages: Hardness reaches 48-52HRC, impact toughness is ≥15J (25℃), tensile strength is ≥1450N/mm², and yield strength is ≥1100N/mm², combining high wear resistance and high strength.
• Good Adaptability: Compatible with 35-40 ton class construction machinery including excavators and loaders (e.g., Komatsu PC300, Hitachi ZX450). It can also be used with adapter series such as 5856-V43.
• Easy Replacement: The vertical drive pin design enables quick replacement, minimizing the impact of mineral powder blockage and reducing maintenance downtime.

  Product Applications

• Mining Operations: Suitable for open-pit mine stripping, quarry rock excavation, etc. For instance, the AD type of V43 tooth holder is particularly designed for quarry applications, effectively excavating and crushing hard rocks.
• Construction Works: Can be used for building foundation excavation, hard soil crushing in road construction and other operations. Its high strength and wear resistance ensure stable performance during long-term construction.
• Pipeline Laying: During pipeline installation, it is necessary to excavate hard soil or rocks. The high penetration and wear resistance of the V43 tooth holder can improve construction efficiency and reduce costs.

  Material Characteristics

• High-Quality Base Material: Made of high-strength alloy cast steel, with some models containing low-carbon alloy components. Formed through precision casting (investment casting) + forging process, it has a dense internal structure that guarantees the overall performance of the tooth holder.
• Excellent Mechanical Properties: Brinell hardness is 470-520HB, featuring good wear resistance and fracture resistance, which can adapt to various complex working environments.
• Reliable Quality: Complies with ISO 9001:2008 standards. Material composition can be customized according to engineering requirements, ensuring the stability and reliability of product quality.
