Festo's CRHD repairable round cylinder series to DIN ISO 6431 is one of the company's new core products for the food, beverage and packaging industries and any other industry demanding the highest standards of hygiene and corrosion resistance. The product's hygienic design cuts cleaning requirements to a minimum - CRHD is compatible with all leading manufacturers' cleaning agents.

The stainless steel cylinders used in the food and beverage industries must meet stringent requirements. Festo's hygienic design products are intended in particular to reduce the times required for CIP (cleaning in place) and SIP (sterilisation in place). The CRHD series features minimal gaps and high surface quality, with a peak-to-valley height Ra of 0,5 to 0,6 µm ensuring rapid draining of liquids.

The CRHD repairable round cylinder series is Festo's new core product for use in food and beverage zones. Its hygienic design cuts cleaning and sterilisation times significantly

Setting a new standard in logical design, the CRHD's cylinder barrel joints to its bearing and end caps are positive locking and mounting components are integrated into the cylinders. Even the adjusting screw of the end-position cushioning has been designed in accordance with hygiene regulations. The rod wiper seal end face is flush with the bearing cap.

The cylinders are easy to clean and resistant to aggressive environmental conditions such as cleaning agents, foodstuff and vapours by virtue of the materials used (AISI 306 for the caps and barrel; AISI 316 for the piston rod). CRHDs are lubricated by an H1 food-industry grease with USDA certification and meet the highest corrosion-resistance requirements (corrosion-resistance class KBK4). At-a-glance features and variants include a choice of rod wiper materials - PUR, FPM, NBR - and air connections at both ends with mirror image sealing surfaces. Piston diameters range from 32 to 100 mm, utilising X strokes of 10 to 500 mm, with an extended piston rod variant (K8). Variant S6 includes heat-resistant seals up to +150°C and a FPM wiper. A choice of two different bearing caps and three different end caps are available, with clevis or strap mounting using the same component.
