Description
Robot Joint Rubber Clamp Pads
Robot Joint Rubber Clamp Pads are precision-molded elastomeric components designed for the joint assemblies of humanoid and quadruped robots. These pads deliver optimal grip, cushioning, and vibration damping for robotic joints, enhancing stability, accuracy, and long-term durability in high-cycle industrial environments. Julong Rubber’s expertise in custom rubber formulation and mold engineering ensures every pad meets the exacting standards of advanced automation.
Key Features
- High Elasticity & Resilience: Engineered from premium SBR (Styrene-Butadiene Rubber), our clamp pads provide superior flexibility and energy return, minimizing joint play and wear.
- Vibration Damping: Effectively absorb shock and reduce vibration transmission between robot limbs and actuators, crucial for high-speed and precision movement.
- Consistent Grip: Advanced anti-slip surface textures ensure secure joint locking, reducing slippage and positional drift during repetitive operations.
- Abrasion & Tear Resistance: SBR offers robust resistance to mechanical abrasion, extending product lifespan under dynamic, heavy-load conditions.
- Environmentally Stable: Retains mechanical properties across a wide temperature range and in challenging industrial settings.
