MATERIAL OPTIONS
The standard material Is only suitable for hydraulic mineral oil applications. Other material options are available for water based (HFA and HFB) fluids and sythetic esters (HEES). In certain sizes a Hythone face material option Is available, particularly for intermittent single actring applications, without the use of remote bearings. Other material options can be supplied. These Include: Hydrolysis stabilised polyester elastomer (Grey 55D) Hydrolysis stabilised polyester elastomer (Red 72D) For full details and availability please contact your local Hailite soles office. |
DESIGN
The Hailite type 770 seal is a double acting compact, low friction seal for light to medium duty hydraulic cylinders. It has been designed to fit standard inch *o' ring housings. It comprises a tough self lubricated elastomeric face which is pre-loaded by a rectangular cross-section expander. It can be used on SG iron pistons or on a piston where there is an adequate remote bearing (see type 506 bearing data sheet).
INSTALLATION
Unlike PTFE seals it Is not generally necessary to use a cone to assemble the type 770 onto the piston, the elastomeric material will stretch sufficiently without problems.
FEATURES
• LOW BREAK-OUT AND OPERATING FRICTION LEVELS.
• RAPID RECOVERY OF FACE AFTER ASSEMBLY. UNLIKE COMMON PTFE FACES, NO RE-SI7JNG IS REQUIRED.
• MORE TOLERANT TO DIRT AND CONTAMINATION THAN COMMON PTFE EQUIVALENTS.
• EXCELLENT WEAR RESISTANCE^
• OPERATES ON A WIDE RANGE OF SURFACE FINISHES.
• IDEAL FOR USE WITH HALUTE HALUTE 506 OR 533 GFN WEAR RINGS |
