WHITTET-HIGGINS防松螺母N系列產(chǎn)品介紹
Most commonly used locknuts, made of low carbon steel, these locknuts are the least expensive but require a lockwasher and the cutting of a keyway in the shaft.
This series meeting SAE-Society of the Automotive Engineers, ABEC-Annular Bearing Engineers Committee and AFBMA- Anti-Friction Bearing Manufacturers Association specifications offers a positive mechanical lock when combined with a lockwasher and keyway.
An 'A' before the locknut designation indicates this size was previously manufactured with 11 threads per inch whereas now they have either 12 or 8 threads per inch. It is recommended that everyone avoid making shaft threads to this now semi-obsolete 11 pitch series. All new designs could best use the 12 and 8 pitch AN series of threads for the greatest assurance of long term compatibility and future availability.
This N-AN series through size AN-26 meets the many exacting requirements for good operation of tapered roller bearings but series PN in all sizes meets specifications for the safest and best operation of tapered roller bearings.
常用的鎖緊螺母，由低碳鋼制成，這些鎖緊螺母需要鎖緊墊圈和軸上的鍵槽切割。
該系列符合 SAE 汽車工程師協(xié)會、ABEC 環(huán)形軸承工程師委員會和 AFBMA 抗摩擦軸承制造商協(xié)會規(guī)范，在與鎖緊墊圈和鍵槽結(jié)合使用時提供可靠的機械鎖定。
鎖緊螺母名稱前的“A”表示此尺寸以前制造時每英寸有 11 個螺紋，而現(xiàn)在它們每英寸有 12 個或 8 個螺紋。 建議大家避免在這個現(xiàn)在半過時的 11 螺距系列上制作軸螺紋。 所有新設(shè)計都可以使用12和8螺距AN系列螺紋，以保證長期兼容性和未來可用性。
N-AN 系列到尺寸 AN-26 滿足圓錐滾子軸承良好運行的許多嚴格要求，但所有尺寸的 PN 系列都滿足圓錐滾子軸承安全和規(guī)范。
