Heavy Duty Direct Link Thumb for Mid-Size Excavator with WBM Wedge Lock Coupler

Serviceable Bushings

The pivot pin bore features greaseable and replaceable hardened bushings, ensuring smooth operation, enhanced durability, and easy serviceability.

Induction Hardened Pins

Thumb includes OEM quality high strength induction hardened pins and locking hardware.

Hard Surface Weld Overlay

Our heavy-duty thumbs come standard with hard facing on tine tips.  Hard facing is a great way to boost wear life and reduce costs for heavy-duty excavation work.

T1 Tines

Our thumb tine plates are crafted from high-strength low-alloy (HSLA) steel, known for its exceptional strength, toughness and wear resistance.  This makes it an ideal choice for heavy-duty applications such as excavator thumbs, where durability is essential.

Spherical Bushings

Our thumb cylinders are equipped with spherical bushings to allow slight angular movement to accommodate misalignment and reduce stress on the cylinder.  This flexibility minimizes wear on seals and other components, enhancing durability and extending the cylinder's lifespan.

Bucket Pin Rotation Axis

Because the thumb and bucket share the same pivot point, the grip angle between the bucket and the thumb remains consistent throughout the rotation.  This allows for a more stable and secure hold on materials of varying shapes and sizes.
