Products Description
Machine‑tool specialization
Developed exclusively for CWK500 machines; dimensions are precisely matched to the original equipment.
Dry‑running adaptability
Supports coolant‑free operation, giving the joint greater flexibility in demanding conditions.
Long‑lasting sealing
The SIC seal ring, together with a balanced mechanical seal, is wear‑ and corrosion‑resistant, extending service life.
Anodized aluminium housing is lightweight and corrosion‑resistant; the steel rotor provides structural stability.
Unique structure
The bearing‑less, disengageable design matches the operating characteristics of machine tools and reduces failure points.
Standard interface
| M12 × 1.5 LH rotor connection + G 3/8″ supply connection – easy to install on existing piping. |
Products Description
A: The bearing‑less, disengageable design is better suited to the CWK500's operating conditions. It eliminates bearing jamming and wear that can be caused by coolant impurities, reduces the number of potential failure points, and simplifies the structure, thereby making maintenance easier and more reliable.
A: Yes. SIC material has excellent chemical‑corrosion resistance and wear resistance, so it can effectively withstand the corrosive action of coolant. Combined with the balanced mechanical‑seal design, it maintains stable sealing performance for a long time and prevents leakage.
