Stainless Steel Gear Units KES.37 und RESF371 Product description

1.1 Housing designThe efficiency-optimized KES.37.. helical-bevel gear units are characterized by an opti-mized housing design and the use of stainless steel. Recesses that can collect dirt andliquid have been eliminated. Thus the gear unit surface is easy to clean and is chemicalresistant.

1.2 Motor mountingThe IEC and NEMA adapters, also made of stainless steel, allow for a variable motormounting.

1.3 Surface protectionThe stainless steel variant is resistant to corrosion according to the operating conditionslisted in section "Cleaning recommendation" in the corresponding operating instructions.

1.4 Ambient temperatureGear units/gearmotors can be used at ambient temperatures between - 20 °C and+ 40 °C . Consult SEW-EURODRIVE if the ambient temperatures exceed this tempera-ture range.

INFORMATIONThe present addendum to the "Gear Units" catalog comprises the KES.37 and RESF37stainless steel gear units.

Please use the data specified in this publication. This document does not replace thecomprehensive "Gear Units" catalog.

INFORMATIONNotes on the shafts illustrated on the mounting position sheets.

Observe the following information regarding the illustrations on the mounting positionsheets:• For gear units with solid shaft: The displayed shaft is always on the A end.• For shaft-mounted gear units: The shaft with dashed lines represents the

customer shaft. The output end ( = shaft position) is always shown on the A end.

INFORMATIONNotes on the illustrated motors. Motors are only represented symbolically on the mounting position sheets.

3.1 Lubricants

3.1.1 General informationUnless a special arrangement is made, SEW-EURODRIVE supplies the drives with alubricant fill adapted for the specific gear unit and mounting position. The mounting po-sition, M1 – M6, must be specified with the order. See "Mounting positions", page 6. Youmust adapt the lubricant fill if you change the mounting position subsequently (� "Lu-bricant fill quantities", page 12).

3.1.2 Lubricant tableThe lubricant table on the following page shows the permitted lubricants for SEW-EU-RODRIVE gear units. Observe the following key to the lubricant table.

Key to the lubricant table

Abbreviations, meaning of shading and notes:CLP PG = Polyglycol (W gear units, conforms to USDA-H1)CLP HC = Synthetic hydrocarbonsCLP HC NSF H1 = Synthetic hydrocarbons (NSF H1 certification)E = Ester oil (water hazard classification 1)

= Synthetic lubricant (= synthetic-based roller bearing grease)= Mineral lubricant (= mineral-based rolling bearing grease)
