Replacement Cylinders

General Dimensions & Specifications

Fronek A/DE offers complete replacement cylinders that come factory preset to customer specifications. They are designed to mate to existing Fronek A/DE hardware and ship coated with a corrosion resistant primer. Alternate coatings can be furnished upon request.
Fronek A/DE can supply two types of cylinder conficurations. Type NF, the extended tie rod configuration, is furnished with a base end mounting arrangment consisting of extended main cylinder tie rods (Figure 1). This type of configuration is compatible with Fronek A/DE’s Fig 510 and Fig 511 hardware. Type M77, the flange mount configuration, is nearly identical to the Type NF except that the base end mounting arrangment consists of a separate flange (Figure 2). Both cylinder types can be furnished for either nuclear or commercial applications.
The part and model numbers provided in the tables below are applicable to "Nuclear" grade product. For ‘Commercial’ grade applications, the part number is increased by 40 and the model number is appended with the letter ‘C’. For example:

‘Nuclear’	P/N 60501, Model No. ADH-2000L
coresponds to
‘Commercial’	P/N 60541, Model No. ADH-2000LC

When ordering, please specify model number, cylinder size, and stroke.
