Product Description
High-Resilience 3315301400 Bushing Retaining Stop Ring for Epiroc SB302 & Atlas Copco SBU340
Secure your hammer’s front-head alignment and eliminate hazardous component migration with Toparts' heavy-duty 3315301400 bushing stop ring. Precision-engineered as a direct-fit locking solution for Epiroc SB302 and Atlas Copco SBU340 solid-body hydraulic breakers, this high-tensile retaining ring keeps the inner/outer bushings rigidly positioned during continuous, high-frequency rock breaking.
The Toparts Engineering Difference: Built to Endure Axial Shock
During demolition, the piston's high-speed stroke creates severe harmonic vibrations and cumulative axial forces that push against the tool guide system. Standard aftermarket snap rings often suffer from hydrogen embrittlement or tension loss, leading to catastrophic bushing displacement. At Toparts, we manufacture the 3315301400 ring with strict structural upgrades:
Premium Spring Steel Formulation: Forged from premium manganese-alloy spring steel (65Mn / Cr-V equivalent) to deliver exceptional elastic limits and superior fatigue resistance. It expands smoothly for installation and snaps back with relentless clamping force.
Isothermal Quenching Process: Every 3315301400 ring undergoes specialized heat treatment to optimize structural toughness. This creates a hard surface that resists notch wear while maintaining a ductile core that absorbs continuous percussion shock without cracking.
Strict Dimensional Parallelism: CNC stamped and double-disc ground to guarantee uniform thickness and perfect flatness. This prevents uneven stress distribution inside the breaker’s internal locking groove, protecting your front head housing from scoring.
Phosphate Anti-Rust Layer: Finished with a heavy manganese phosphating coating, offering superior oil-retention and corrosion defense in wet tunneling or trenching environments.
