Not all crusher parts are created equal. If you’ve been relying on OEM crusher replacement parts because they seem like the “safe” choice, it might be time to take a closer look.
Unlike OEMs, who design for mass production, not for the daily demands of your circuit, material, or uptime targets, Optimum Crush, expertise lies in designing parts that are tailored to your specific needs. We work with mines worldwide that have made the switch after realizing their OEM parts were doing more harm than good.
Here are five clear signs it’s time to stop using OEM parts and start using parts built to perform.
1. You’re Replacing Your OEM Crusher Replacement Parts
If you’re burning through liners faster than expected, your wear patterns aren’t the only problem.
OEMs build parts to meet average specs, not to match your material or chamber geometry. The result?
- Shorter wear life
- More frequent shutdowns
- Increased labor costs
Optimum Crush designs for longer-lasting performance—and it shows. We back our parts with the lowest warranty rate in the industry at just 0.17%.
2. You’re Seeing Uneven Wear or Poor Fit On Your OEM Crusher Replacement Parts
Uneven mantle wear. Misaligned liners. Inconsistent performance from “new” parts. Sound familiar?
These issues are a red flag that your OEM parts aren’t fitting the way they should. Poor fit leads to:
- Vibration and stress on the machine
- Increased energy draw
- Reduced output
Switching to custom-engineered parts improves performance and extends the life of your entire machine.
3. Lead Times Are Costing You
If you’re tired of waiting weeks (or months) for a critical replacement part, it’s time to take back control and stop bleeding money.
Downtime costs stack up fast. And when you’re dependent on OEM delivery schedules, you’re not in control.
Optimum Crush stocks high-demand crusher parts and delivers fast, helping you avoid costly shutdowns and schedule disruptions.
4. Your Warranty Claims Are Going Nowhere
The industry average for part failure claims sits around 3%. That may sound small, but when it hits your operation, the cost is big.
At Optimum Crush, we’re proud to maintain the lowest warranty rate in the industry—under 0.17%. That’s not luck. It results from precision engineering, tighter quality control, and parts built specifically for your crushers.
If your OEM supplier won’t stand behind their parts like that, it’s time to rethink who you trust.
5. You’re Doing All the Problem-Solving
OEMs are great at selling parts, but not always great at solving problems. If your team is left troubleshooting independently, you’re not getting the support and partnership you deserve.
We don’t just ship parts. We show up. We troubleshoot. We provide data, training, and direct engineering support to help you get the most from every crusher in your plant.
That’s the difference between a vendor and a partner.
