Original BOCI Water-cooled Locking Ring BLT643 DP.M.Q0393AA

✅ Precision locking seal prevents water leakage and lens burnout
M16×1 high-precision fine-pitch thread ensures even force distribution to prevent chipping of the ceramic; the end face presses against the seal ring to provide a zero-leakage high-pressure water cooling system, preventing coolant from corroding the optical lenses and reducing lens wear.
✅ 304 quenched and tempered stainless steel, heat-resistant and distortion-free
Withstands prolonged machining of high-power, thick plates; resists arc and slag corrosion; threads are resistant to stripping and seizing, offering a longer service life than standard carbon steel locking rings.
✅ Non-slip knurled outer ring for quick, tool-free installation and removal
Can be installed or removed by hand; replacing water-cooled ceramic components takes just 5 minutes, reducing production line downtime.
✅ Original 1:1 replacement, ensuring coaxial stability and fewer alerts
Compatible with the original DY.C.A0009AA water-cooled ceramic, with zero dimensional deviation; the ceramic remains level, ensuring reliable contact at the capacitive contacts, reducing nozzle height error alerts, and making it suitable for unmanned automated production lines.
✅ Balanced stress distribution protects the ceramic and extends service life
Pressure is evenly distributed, preventing single-point compression cracks; maintains a constant water-cooling temperature, reducing thermal shock to the ceramic, and decreasing ceramic replacement frequency by 2–3 times
