Key Takeaways:
Marusaku hydrostatic rotary tables use an air-curtain seal to keep chips and coolant out of the oil film without mechanical contact. Learn the benefits over lip seals.
Sealing Challenge
A 转台 sits在 storm的chips, coolant,与dust. If contaminants enter 油膜, 刚度与精度 degrade. But rubbing lip seal 会 reintroduce contact 摩擦—defeating purpose.

Air-Curtain Solution
An air-curtain seal blows thin, continuous stream的clean air across gap, creating invisible barrier 该 保持 chips与coolant out 同时 table rotates freely采用zero contact.
Benefits
- No mechanical contact → no 摩擦, no wear
- Effective against chips, mist,与dust
- 保持 油膜 clean → stable 精度
- Long 使用寿命, low 维护
为何 It Fits Hydrostatics
Because whole 轴承为无接触, 无接触 seal为 consistent choice—preserving table's core 优势的摩擦-free, wear-free operation.
