BS type piston rod seal is a type of seal consisting of two sealing lips located on the outside The diameter is a tight fitting lip seal. Due to the difference between the two lips There is a lubricant in the middle, which greatly prevents dry friction And wear and tear. In some cases, this type of seal can even be used To replace expensive serial configurations. Main advantages Excellent wear resistance, impact resistance, and extrusion resistance. Low compression deformation. Adapt to the most demanding working conditions. Due to the pressure medium between the sealing lips having Adequate lubrication. Improved sealing performance under part pressure. Extremely prevents external air from entering. Easy to install. technical parameter Working pressure: ≤ 400bar Working temperature: -30 ℃~+100 ℃ Reciprocating speed: ≤ 0.5m/s Mainly used for heavy-duty walking machinery and piston rods in static pressure The sealing, groove and diameter dimensions of the plunger comply with IS05597/1 According to the requirements of the international standard IS03320. Media Hydraulic oil (mineral oil based) Installation This type of seal should have an axial clearance (see columns H and L). To avoid damage to the sealing lip, do not install the seal Pull the seal onto the sharp edge.
