YXd type shaft type shaft seal ring YXd specifications and groove dimensions Table I, Properties and Uses YXd type shaft seal is a lip seal prescribe an outer diameter of the tight fit of the lip seal. Because additional lubricant between the two lips, it greatly prevent friction and wear. In some cases, this seal may even replace expensive series arrangement. The main advantage is that excellent wear resistance, impact resistance, to fight a small compression deformation, improved sealing performance under zero pressure. For the most demanding working conditions, an excellent way to prevent outside air from entering to achieve a good seal. Second, the material imported polyurethane PU. Third, the mining conditions Operating pressure: ≤40MPa; Working temperature: -35 ~ + 100 ℃; Working medium: Hydraulic oil (mineral oil based); Reciprocating speed: ≤0.5m / s. Fourth, the design criteria and the groove dimensions, tolerances, etc. in line with JB / ZQ4265-86 standards.
