Product Description

A standard type double acting single rod air cylinder.
[Features]
· ISO standard (6432) compliant (C85).
· Part numbers are set for products with mounting brackets, rod-end brackets and auto switches.
· As it is no longer necessary to order the bracket and the applicable cylinder separately, ordering time can be reduced.
· Easy fine adjustment of auto switch position.
· Transparent switch bracket improves visibility of indicator LED.
*See the manufacturer's catalog for detailed specifications.

Calculation (Example): C85N20-50NV

Basic weight: 179 g (ø20 [20‑mm diameter])
Additional weight: 8.1 g (at 10‑mm stroke)
Cylinder stroke: 50 mm
Mounting bracket, Clevis: 85 g
Accessory, Rod end: 45 g

179 + 8.1 × 50/10 + 85 + 45 = 350 g
