Variation or loss of air pressure can lead to unwanted movement of vertically mounted pneumatic cylinders under load. Piston rod locks prevent rod travel, potential accidents and subsequent damage and loss.

 

The well established cylinder locking devices types FEL, FEDL and FEDK supplied by

FS Engineering (Automation Systems) Ltd consist of two components:

a) the cylinder adapter bracket with and b) an inserted rod lock cartridge.

 

The obvious advantages over single component units are:

a) the possibility of quick, easy and cost effective replacement of worn or damaged cartridges and b) the use of individual cartridges for custom designed rod lock applications.

 

The compact variant, type FEDK is technically identical to the FEL & FEDL models, but their cartridges are much shorter hence enable design engineers to fit them into tight space where the longer FEL & FEDL cartridges might cause a spot of bother.    

 

Because the cartridges are shorter in length but wider in diameter they are not interchangeable with the FEL & FEDL series.

 

Like their FEL & FEDL siblings, FEDK cartridges are also made of spring loaded high quality brass wedge clamps which provide fast, reliable and secure clamping in any position and without marking the rods.

 

The patented wedge and piston assembly sits in an enclosed black (FEL) or red (FEDL & FEDK) anodised aluminium barrel. A simple, well proven system that provides a highly effective, easy to install low cost method for stopping unhelpful linear rod motion on standard or special purpose applications.  

 

FEDL & FEDK locking sets comprising cartridge and adapter are available for ISO 6431/6432 cylinders from 12 to 125 mm bore (FEL 12 to 200 mm) with retaining forces from 180 to 8,700 N (FEL 200 to 12,000 N). Individual cartridges are supplied for rod diameters from 6 to 32 mm (FEL 6 to 40 mm). For product details please download the PDF file "Rod Locks Data Sheets".

 

Pneumatic cylinders to be equiped with rod locks require an extended piston rod.

 

The devices are maintenance free, work with filtered, lubricated or dry compressed air with operating pressures from 4 to 10 bar in ambient temperatures from -20ºC to +80ºC.

 

The FEDK version provides passive locking, meaning they need air to release the rod and will clamp again when the air pressure falls below 4 bar.

 

Active locking requiring air to clamp the rod are available with some FEL & FEDL version as well as the optional provision of lock on or off sensing with FEL cartridges.

  • Locking-Sets comprising cartridge and

        adapter to cylinders from  D12 to 200 mm  

  • Cylinders require an extended piston rod

  • Cartridge and adapter in anodised aluminium

  • Maintenance free

  • Medium: Filtered, lubricated or dry

        compressed air, max temp. 80º  

  • Operating pressure: 4 to 10 bar

  • Ambient temperature: -20º to +80º
