Hydraulic unit model УСГ 500.2, УСГ 500.2Т
Purpose
Hydraulic unit models УСГ 500.2, УСГ 500.2Т (USG 500.2, USG 500.2T) are for drives of working bodies of presses.
Climatic category of the hydraulic units is NF. Category of placement is 4.2 in accordance with GOST 15150-69.
The hydraulic unit operates on pure mineral oil with kinematic viscosity of 20-35 mm2 / s at oil temperature of 15 ... 50 ° C and ambient temperature of 1 ... 45 ° C.
The cleanliness class of the working fluid is not lower than 12 according to GOST 17216-71. The nominal fineness of filtration is 25 μm.
Recommended brands of oils: ИГП-30, ИГП-38 ТУ.3.810.1413-78 ВНИИ НП-403 GOST 16728-78, industrial И-20А - И-40А according to GOST 20799-88.
Note: УСГ 500.2Т (USG 500.2T) differs from УСГ 500.2 (USG 500.2) by the absence of an ejector line.
