P-X series industrial gear units

Many applications in bulk materials handling or environmental and recycling technology depend on drives with high torques. SEW-EURODRIVE has the solution: a perfectly coordinated unit consisting of planetary gear units and standardized primary bevel-helical gear units.

High torque, high thermal rating

If you need a compact, cost-effective solution with high thermal ratings, our planetary gear units of the P-X series are the right solution. These standardized, powerful industrial gear units combine planetary gear units of the P series with primary gear units of the proven X series of industrial gear units. As an added benefit, all the mounting options and optional features of the X series are also available for this solution.

To achieve the best possible thermal ratings, we take a holistic approach to surface cooling in the P-X gear unit: On the one hand, the cooling fins on the primary gear unit housing significantly increase the surface area of the gear unit. On the other hand, the radial fan in the motor adapter generates a strong air flow. This effectively cools the areas where the main heat is generated.

In addition, a special feature provides even more cooling in the P-X transmission. The cast-on intermediate flange on the primary gearbox connects the two gear units, creating a shared oil chamber. This ensures optimum oil circulation between the two gear units. In this way, excess residual heat is dissipated from the planetary gear unit by cooling oil.

The P-X series planetary gear unit thus combines all the advantages of two pioneering industrial gear unit concepts.

Compact, flexible and cost-effective

Whether hollow shaft or solid shaft, with or without a key, smooth or spline according to DIN 5480, horizontal, vertical or angled mounting position – the P-X series offers you a number of options.

Cost advantages result for your stockholding - thanks to the reduced number of spare gear units for the machines with dual drives. This is because the P-X gear unit, in line with its X series primary bevel helical gear unit, has a reversible housing that can be used flexibly on both sides of the machine. And coupled with the high level of operational reliability, maintenance and servicing costs can also be reduced.
