NDT

Product catalog summary

Overview: The document discusses the NDT lip seal designed for telescopic cylinders, which serves as an enhancement to the TDT seal. The NDT seal offers improved smoothness but operates under a lower maximum pressure compared to the TDT.

Specifications: The NDT lip seal is intended for use in telescopic cylinders with low installation grooves, providing excellent stick-slip properties. It is made from standard RUP materials and is suitable for hydraulic fluids. The standard pressure is 250 bar, with a temperature range of -35°C to +100°C, and a sliding speed of 1 m/s.

Design and Installation: The seal is designed to be kidney-shaped and inserted into the groove with the sealing lip facing the pressure direction. Surface quality requirements include sliding surfaces with Ra 0.1-0.3 µm and Rt ≤ 1.5 µm, groove base with Ra ≤ 0.8 µm and Rt ≤ 3.6 µm, and groove sides with Ra ≤ 2.3 µm and Rt ≤ 15 µm.

Dimensions and Ordering: The document provides a detailed table of available dimensions for the NDT lip seal, ranging from diameters of 45 mm to 200 mm. Each size is associated with a specific reference number for ordering. Further dimensions are available upon request.

Allowable Gap Sizes: The document includes a table specifying allowable gap sizes for different diameter ranges, with a maximum gap size of 0.3 mm for diameters less than 69 mm and 0.35 mm for diameters between 69 mm and 200 mm.
