Supply X156H Heavy Duty Bucket Teeth for Excavator Skid Steer Loader

1. Product Overview

The X156H bucket tooth is a heavy-duty upgrade to the standard Hensley 156 parabolic series.
Designed for operators who demand maximum durability, the “H” designation stands for “Heavy Duty,” meaning it is cast with additional wear material compared to standard dirt teeth.
This makes the X156H highly capable of handling abrasive materials, rocky terrains, and severe digging applications without compromising machine performance.

2. Detailed Specifications

3. Key Features

• Enhanced Wear Material: The X156H is specifically cast with a thicker, heavier profile than the standard X156, providing a significantly longer lifespan when working in highly abrasive conditions.
• Parabolic Design: The 156 series features a parabolic fit system that helps distribute impact and stress across the adapter rather than relying entirely on the pin.
• High-Grade Alloy Steel: Manufactured from premium alloy steel, these teeth offer a high level of hardness and rugged resistance to extreme wear and tear.
• Universal Compatibility: Provides a perfect fit for existing Hensley style 156 series adapters, meaning no expensive bucket modifications are required.

4. Applications

The X156H is an incredibly versatile tooth, optimized for heavy digging, trenching, mining, and general construction. It is compatible with a massive fleet of compact and mid-sized machinery, including:

1. Kubota K/KX Series Excavators: KX033-4, KX040-4, KX71, KX91, KX121, KX161.
2. Kubota U Series Excavators: U25, U35, U45, U55 models.
3. Skid Steer Loaders: Compatible with universal Bobcat-style X156 X Series adapters.
4. Mini Excavators & Backhoes: Fits various standard backhoe loader buckets utilizing a 1-5/8″ pocket width.

5. Information on Accessories

To ensure safe and reliable installation, the X156H bucket tooth requires the correct fastening hardware:

1. Fastening Pin: It utilizes a top-pinned vertical roll pin, commonly referenced as part number P156 or 156LPN.
2. Pin Dimensions: The standard compatible pin is generally 2-1/4″ in length with a 3/8″ diameter.
3. Adapters: The tooth mounts exclusively to Hensley Style 156 series weld-on or bolt-on adapters.

6. Manufacturing Process

The creation of an X156H bucket tooth relies on modern metallurgical science to ensure field reliability:

1. Precision Investment Casting: The raw alloy steel is melted and poured into highly precise molds, which guarantees that the 1-5/8″ inner pocket matches the adapter perfectly, preventing wobble and sheer stress.
2. Heat Treatment (Quenching & Tempering): The cast teeth undergo a rigorous thermal process to increase the steel’s molecular hardness while maintaining enough ductility to absorb high-impact shocks without snapping.

7. Common Industry FAQs

Q1: What is the difference between the X156 and the X156H?

A: The base X156 is the standard-duty general-purpose bucket tooth. The X156H (Heavy Duty) utilizes the exact same fitment and adapter but features a thicker casting with extra wear material for high-impact and abrasive digging environments.

Q2: Can I use the X156H on my Kubota mini excavator?

A: Yes, if your Kubota bucket is equipped with the 156 Series vertical roll pin tooth system. It is a direct OEM equivalent for Kubota part number 77700-03180 and fits popular models like the KX71, KX91, KX121, U35, and U55.

Q3: Does the tooth come pre-painted or coated?

A: While some aftermarket parts are shipped with a protective paint layer (like black, grey, or red), others are sold as raw, uncoated steel ready for immediate use. Paint on a bucket tooth is purely cosmetic and wears off within the first few minutes of digging.

Q4: How do I remove and install an X156H tooth?

A: Because it utilizes a vertical roll pin system, you can easily remove the old tooth by using a punch and a heavy hammer to drive the pin out from the top down. To install, slide the X156H onto the adapter and hammer a new P156 pin down through the aligned top hole.
