Perfect fit for my custom rig
This bushing fits perfectly into the hydraulic cylinder of my large-scale toy excavator. The self-lubricating feature makes the arm movement incredibly smooth.

Good quality but tight fit
The material quality is excellent and feels very durable. It was a bit tight to install initially, but once seated, it works flawlessly.

Great replacement part
My son's favorite toy excavator had a worn-out liner. This replacement brought it back to life. The copper lining seems very robust.

Excellent durability
After weeks of heavy play, there is no sign of wear on the bushing. The self-lubricating aspect really helps keep the toy running quietly.

Works well but specific sizing
Make sure to measure your cylinder exactly before buying. It worked for the 90x77 size I needed, but the tolerance is quite precise.

Smooth operation guaranteed
I use these for various educational robotics projects. The single-side steel sleeve design provides great stability without adding too much weight.
Q: Is this bushing suitable for real heavy machinery?
A: No, this product is specifically designed for toys, strollers, and educational play equipment simulations, not for actual industrial heavy machinery.
Q: What tools are needed to replace the old bushing?
A: Typically, a small rubber mallet and a press tool or a sturdy flat surface are sufficient to press the new liner into place safely.
Q: Which dimension should I choose for a standard 1:14 scale excavator?
A: Most 1:14 scale models utilize the 70x60mm or 90x77mm sizes. Please check your specific model's manual or measure the existing liner to be sure.
Q: Do I need to apply grease during installation?
A: No, the bushing features a self-lubricating copper lining, so additional grease is not required for normal play conditions.
Q: Can this be used in outdoor play sets?
A: Yes, the corrosion-resistant treatment allows for outdoor use, though we recommend storing the toy indoors when not in use to maximize longevity.
