Merit 3363 0894 80 Lower Bushing | Precision Alignment for Epiroc HB Series

Why Choose Merit 3363 0894 80?

1. Forged Strength for Extreme Conditions

While standard cast bushings often fail under the lateral stress of prying, Merit bushings are manufactured from high-grade forged alloy steel. The forging process creates a superior molecular structure, allowing the part to absorb massive shockwaves and withstand the "lever effect" without cracking.

2. Advanced Induction Hardening

Our bushings undergo a proprietary deep-case induction hardening process. We achieve a surface hardness of HRC 56-60, creating a shield against the abrasive dust and rock fragments typical of quarrying and mining, while the core remains ductile to prevent brittle fracturing.

3. Precision-Engineered Lubrication Channels

Friction is the enemy of productivity. The Merit 3363 0894 80 features CNC-machined internal grooves designed to work in perfect harmony with automatic lubrication systems. This ensures an even, constant film of chisel paste, preventing "cold welding" (galling) and seizing.

The Strategic Advantage for Your Fleet

• Piston Protection: By eliminating tool "wobble," our bushing ensures the piston strikes the tool perfectly center, preventing catastrophic piston scoring and seal leaks.
• Front Head Integrity: Replacing your bushing at the correct interval protects the expensive front head housing from direct impact damage.
• Seamless Compatibility: A 1:1 precision match for Epiroc HB 2000, HB 3100, and HB 4700 models—install with confidence, no modifications required.
