K 764
DESCRIPTION
The type K 764 is a compact piston seal designed primarily for use in lightweight hydraulic applications. This seal is recommended for double acting piston aplications, that must achieve minimal leakage. Moreover it has improved properties at temporary one-side pressure load. K 764 consists of excellent wear resistant profile ring and the O-Ring which is the preloading part. We recommend to use guiding rings which are use on one or both sides. You can find technical data for guiding strips of category F 87 and F506 in relevant data sheets. Marked housing follow ISO 7425 - Part 1.
Advantages
- double-acting seal with improved properies of single-acting properities
- excellent wear resistant
- improved dynamic and static tightness due to new designed seal geometry
- dirt resistant
- good material elasticity ensures quick and easy mounting
- the additional calibration isn't require
MEDIA
This seal standardly with NBR O-Ring is suitable to run in liquids based on mineral oil from -40°C to +100°C. The temperature range to +40°C is allowed for water, pressure liquids HFA at the standard materials. Other media resistance is a subject to request.
