Angular Contact THRUST Ball Bearing (NSK)
Angular Contact Thrust BallBearing
Maker : NSK
Numbering System of High-Speed Angular Contact Thrust Ball Bearings (ROBUST Series)
주 1)TAC (NSK) 계열의 베어링은 생산 중단 되었습니다
2) 종래의 TAC 계열을 사용하고 있는 주축에는 BAR (30 ° contact angle),BTR : 40 ° contact angle
베어링으로 교체되었으며, 축과 하우징을 변경하지 않고 Collar 치수만 C에서 D로 길이를 늘이는 것만으로 변경이 가능합니다.
3) BAR , BTR 베어링은 외륜이 Angular Contact Thrust Ball Bearing 보다 작으므로
상호간에 호환성이 없습니다.
(☞ 베어링의 조립 틈새 참조)
