Hydraulic fluid power. Cylinders. Rectangular bearing ring housing for rods and pistons. Dimensions.
La présente norme est destinée à faciliter l'interchangeabilité des dispositifs de guidage à section rectangulaire pour tiges de piston et pistons de vérins hydrauliques. Pour cela, elle fixe les dimensions et les tolérances des logements auxquelles doivent se conformer les fabricants de joints et de dispositifs de guidage.

ISO 10766:2006 specifies the preferred range of nominal dimensions and associated tolerances for a series of hydraulic cylinder piston and rod housings for rectangular-section-cut bearing rings, of the type shown in Figure 1, for applications in the following range of dimensions: for cylinders with bores of 16 mm to 500 mm, inclusive;for rods with diameters of 12 mm to 360 mm, inclusive. ISO 10766:2006 does not give details of cut bearing ring design, because the manner of construction of cut bearing rings varies with each manufacturer.The design material of cut bearing rings and any incorporated anti-extrusion component are determined by conditions such as temperature and pressure.
