Products Description
The SEW K57-DRN90L4 is a robust drive solution engineered for industrial environments that demand high torque density and exceptional mechanical endurance. Unlike smaller units, the K57 is optimized for intermediate heavy-duty cycles, offering a significant boost in torque-up to 600 Nm-without a massive increase in footprint.
Equipped with the DRN90L4 IE3 motor, this 1.5kW unit ensures maximum energy conversion with minimal heat dissipation. Its helical-bevel gear design provides a significant efficiency advantage over worm-drive alternatives, maintaining over 90% efficiency across its entire speed range. This makes it an ideal choice for facilities looking to reduce carbon footprints while increasing system uptime.

FAQ
Q: What is the main benefit of choosing K57 over K47 for a 1.5kW application?
A: While both can use a 1.5kW motor, the K57 provides a much higher "Service Factor." This means it can handle higher shock loads and frequent start-stop cycles without internal gear fatigue.
Q: Does the K57 require specific oil for high-temperature environments?
A: For ambient temperatures above 40°C, we recommend using synthetic lubricants (CLP PG). Standard mineral oil (CLP VG220) is provided for normal industrial conditions.
Q: Can this unit be mounted vertically?
A: Yes, the K57 supports various mounting positions (M1 through M6). Please specify vertical mounting when ordering so we can ensure correct oil level and venting.
