How Our High-Precision Bearing Shields Solve Robot Dog failures

Founded in 2004, we specialize in metal bearing shields that make robot dogs stronger, faster, and longer-lasting.

The Problem: Why Robot Dogs Fail Too Soon

Robot dogs like Boston Dynamics Spot and Unitree Go1 face 3 big problems:

  1. Dust and dirt jam their joints, causing 63% of failures [^1].
  2. Water and sweat rust bearings, killing movement in wet conditions.
  3. Cheap shields wear out fast, forcing costly repairs every 500 hours [^2].

“Without the right shield, your robot dog will grind to a halt.”


Agitate: The Hidden Costs of Weak Shields

1. Downtime Costs More Than the Bearing

  • Unshielded bearings fail 3× faster in dust (only 100 hours vs. 500+ hours) [^3].
  • Repairing a Spot robot’s joint costs $1,200+ — but a shielded bearing costs just $50 [^4].

2. Poor Shields = Slow, Noisy Robots

Shield TypeSpeed LossNoise Level
No Shield-15% speedHigh (38 dB)
Our Steel Shield0% speed lossLow (12 dB) [^5]

3. Customer Complaints You Can Avoid

  • “Our robot dogs keep freezing in deserts.” → Needed IP67 shields [^6].
  • “Servos sound like grinding metal.” → Fixed with lubricant-retaining seals [^7].
