2 Lubricant selection/lubricant table.2 Lubricant selection/lubricant table The oil viscosity and type (mineral/synthetic) to be used are determined by SEW- EURODRIVE specifically for each order. This information is noted in the order confirmation and on the gear unit's nameplate. Any deviation from these conditions requires consultation with SEW-EURODRIVE..2.1 General information on selecting the oil Unless a special arrangement is made, SEW-EURODRIVE delivers the drives without oil. This does not apply to auxiliary drives and primary gear units. This means the gear unit must be filled with the correct oil grade and quantity before startup. You may find the corresponding information on the nameplate of the gear unit. The following tables provide an overview of mineral and synthetic oils Mineral oil Standards Synthetic oil Standards Lubrication oils are divided into ISO VG viscosity classes according to ISO 3448 and DIN 119.

3 Lubricant selection/lubricant table In addition to the required viscosity, the oil must fulfill the following criteria: CLP oils according to DIN Micro-pitting test according to FVA, FV no. 4/ I-IV, GFT class high, damage force level >10 If synthetic oil is used, SEW-EURODRIVE recommends polyalphaolefin-based oil (CLP HC). Observe the operating temperature of the gear unit when specifying the oil change intervals. If required, a cooling system must be used or the oil change interval must be shortened (see "Lubricant Change Intervals" in the "Helical and Bevel-Helical X.. Series Gear Units operating instructions)..2.2 Permitted lubricants The standard for viscosity and oil grade is the type of oil that is specified by SEW- EURODRIVE on the order (see order confirmation and nameplate). Consult SEW-EURODRIVE if you use bio and food grade lubricants or polyglycol oils. Check the compatibility of the greases and oils used. Key to the lubricant table The lubricant table shows the permitted lubricants for SEW-EURODRIVE gear units. This information is provided to preselect the lubricant. The proper and final lubricant selection is made by SEW-EURODRIVE to match the specific project. Consider the used abbreviations, meaning of shading and notes. CLP = Mineral oil CLP HC = Synthetic polyalphaolefin E = Ester oil (water hazard classification 1) = Mineral lubricant = Synthetic lubricant 3) = Lubricants may only be used if service factor F s 1.3 4) = Take into account critical startup behavior at low ambient temperatures 6) = Ambient temperature = Lubricant for the food industry (food grade oil) = Biodegradable oil (lubricant for agriculture, forestry, and water management) Oil Oil 72 Catalog X..

The purpose of a gear unit breather is to relieve pressure that occurs from heating during operation. The gear units are normally equipped with a high-quality breather filter with a filter mesh of 2 µm. The gear unit is equipped with an oil drain plug as standard.

The pump is mounted externally to the gear unit and is driven by the input shaft or intermediate shaft of the gear unit, assuring high reliability of the pump. Different pump sizes are available. Adequate flow rate for the specific application depends on the following factors: Oil quantity required to supply the points Pump position (connected to input shaft or intermediate shaft) Gear unit ratio Speed range of the gear unit Proper functioning of the shaft end pump is monitored via the connected pressure switch. See page 127. Consult SEW-EURODRIVE for selecting the suitable flow rate. For dimensions, see page 419. A minimum input speed is required for the shaft end pump to operate properly. If you use variable input speeds (e.g. inverter-controlled drives) or if you intend to change the input speed of a gear unit equipped with a shaft end pump, you must contact SEW-EURODRIVE Catalog X..

20 Accessories Motor pump /ONP Structure With pressure, a motor pump supplies all bearing points and gearing above the oil sump with oil via internal piping. A motor pump is used, for example, if the required speed of the shaft end pump (> 400 rpm) is not reached. It is also used in an inverter operation where a shaft end pump cannot be used or can only be used under certain circumstances. The motor pump is mounted externally to the gear unit and depends on the speed of the gear unit.

Warning or switch-off signal when the oil pressure reaches < 0. bar Option: Temperature switch with trip point for monitoring the cooling group, i.e. warning or gear unit shutdown when the oil temperature exceeds 194 F. The following pump mounting types are available: Directly mounted on the gear unit, including piping On the mounting frame, for separate installation, but without piping to the gear unit The customer has to connect the wiring for the following items: switch to the customer's evaluation unit Electrical contamination indicator of the oil filter Pump motor Option: Between temperature switch and pump motor Catalog X..
