New Premium Sine Seal Oil Seal

DCS SEW Eurodrive Premium Sine Seal Oil Seal 1 400

Oil seals are used to seal rotating shafts and to both protect the gear unit against dirt from outside and to protect the production environment from leaking lubricant. The oil seals must be able to withstand variable speeds, the pressure inside the gear unit, various temperature requirements and a range of other conditions.

Sealing solutions for gearmotors

Oil seals in today's production systems are subject to increasingly challenging conditions and requirements. Our gear units, and therefore the sealing systems, are used in machines that run at variable speeds or at continuous duty and therefore cause the temperatures in the drive system to fluctuate. The pressure inside the gear unit also varies according to the capacity utilization.

SEW-EURODRIVE employs a special sealing systems to protect your system against leaking lubricant, to protect our gear units against outside dirt, and to protect the motor against oil expelled from the gear unit.

In addition to conventional oil seals, SEW-EURODRIVE now offers a completely NEW, optional sealing ring that was developed specially for us: the Premium Sine Seal. This oil seal was developed for the input motor shaft in gearmotors in collaboration with Freudenberg Sealing Technologies.

The advantage of the new Premium Sine Seal is that its sinusoidal sealing lip exhibits substantially increased durability, and during servicing the new oil seal can be placed in the same location on the shaft because the Premium Sine Seal does not cause any run-in on the shaft. The special shape of the sealing lip means that the contact area on the rotating shaft is larger, which improves both heat dissipation and the transfer of lubricant at the sealing surface.

Benefits at a glance

Wear reduced: on the sealing lip by about 50%

Expected service life longer: by a factor of 2 (compared to othe
systems on the market), which means longer maintenance intervals

No run-in: or wear on the shaft - replacement oil seals can be installed at the same location

Improved reliability: against leakage with increased system availability

Put to the Ultimate Test – Part 1: Torsion Tests by HELUKABEL

DCS Put to the Ultimate Test Part 1 Torsion Tests by HELUKABEL 1 400x275

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.

For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
