KSN KABUTO SEAL CENTER with NUT
Structured to keep cutting water away by means of oil seal.
The waterproofing function still works under slower rotation.
The replacement head enables cost reduction.
- See page HEAD LIST for center head types.
- See page ALLOWABLE LOAD & MORSE TAPAR for revolutions per minute.
- Type KSN has the same waterproof structure as that of type KS.
- We recommend that type KFN be used for fine machining or light metal working.

(while KSN-5 comes with the center head 5A60° and DHN-2).
