An excavator tooth pin, also known as a tooth pin or tooth lock pin, is a component used to secure the bucket teeth onto the adaptor or tooth holder of an excavator bucket. It is an essential part of the tooth assembly, ensuring that the tooth remains securely attached during excavation and loading operations.
Some key points about excavator tooth pins
1. Function: The primary function of an excavator tooth pin is to provide a secure and reliable connection between the bucket tooth and the adaptor or tooth holder. It prevents the tooth from dislodging or coming loose during heavy-duty digging and loading.
2. Design: Tooth pins are typically cylindrical in shape, with one end featuring a head or flange and the other end having a hole or groove for attaching a retaining clip or lock. The dimensions and design of the pin may vary depending on the specific tooth and adaptor configuration.
3. Materials: Tooth pins are commonly made from high-strength alloy steel to withstand the heavy forces and impacts encountered in excavation applications. The choice of material ensures durability, resistance to wear, and reliable performance.
4. Retaining Clips or Locks: In addition to the tooth pin, a retaining clip or lock is used to secure the pin in place and prevent it from coming out. The retaining clip is typically inserted into a groove or hole on the pin, ensuring a secure connection.
5. Replacement and Maintenance: Tooth pins can wear out over time due to the constant stress and abrasion they endure. When a tooth pin becomes worn or damaged, it should be replaced promptly to maintain the proper attachment of the tooth. Regular inspection and maintenance of tooth pins are crucial to ensure optimal performance and safety.
Types of excavator tooth pins
There are several types of excavator tooth pins available, each designed to fit specific tooth and adaptor configurations. Here are some common types of excavator tooth pins:
1. Standard Pin: Standard tooth pins are the most commonly used type. They have a cylindrical shape with a head or flange on one end and a hole or groove on the other end for attaching a retaining clip. Standard pins are available in various sizes and are compatible with a wide range of tooth and adaptor systems.
2. Multi-Lock Pin: Multi-lock pins, also known as Hensley-style pins, feature multiple grooves along their length. These grooves provide flexibility in adjusting the tooth position to compensate for wear. Multi-lock pins are often used in heavy-duty applications where teeth may experience significant wear.
3. Master Pin: Master pins are longer and larger in size compared to standard pins. They are used in conjunction with a master adaptor, which allows for the attachment of multiple teeth in a single assembly. Master pins provide increased stability and strength when multiple teeth are required.
4. Pin and Retainer Systems: Some tooth systems use integrated pin and retainer systems where the pin and retaining clip are combined into a single unit. These systems offer convenience and ease of installation, as the pin and retainer do not need to be installed separately.
5. One-Piece Pin: One-piece tooth pins are designed without a separate retaining clip. They have a built-in locking mechanism or a modified shape that ensures the tooth remains securely attached to the adaptor. One-piece pins eliminate the need for a separate retaining clip, simplifying the installation process.
Price range for excavator tooth pins
The price range for excavator tooth pins can vary depending on factors such as the type of pin, brand, quality, size, and where you purchase them. Additionally, market conditions and location can also influence the price range. It's important to note that the prices mentioned here are approximate and can vary significantly. Here is a general overview of the price range for common types of excavator tooth pins:
1. Standard Pins: The price for a standard tooth pin typically ranges from $5 to $15 per pin, depending on the size, brand, and quality.
2. Multi-Lock Pins: Multi-lock tooth pins are generally priced between $8 and $20 per pin, depending on the size, brand, and quality.
3. Master Pins: Master tooth pins, being larger and more specialized, can range in price from $10 to $30 or more per pin, depending on the size, brand, and quality.
4. Pin and Retainer Systems: Integrated pin and retainer systems are typically priced between $10 and $25 per unit, depending on the brand, quality, and compatibility with specific tooth and adaptor systems.
5. One-Piece Pins: One-piece tooth pins can range in price from $10 to $30 or more per pin, depending on the type, brand, and quality.
These price ranges are rough estimates and can vary significantly based on the factors mentioned earlier. It's recommended to contact suppliers, manufacturers, or dealers for specific pricing information and to compare prices from multiple sources to ensure you are getting the best value for your investment.
