...Drives, Roller Screw Drives, Designs The product range of GSA AG includes four types of roller screw drives that differ in their functionality and characteristics. The drives are manufactured according to standard dimensions, but also based on custom designs. All components are produced and assembled in-house at GSA AG / Gewinde Ziegler AG. Roller screw drives are fundamentally used wherever an...

...Installation is simple as no chain or belt drives or gear reduction motors are required. Pumps can be directly connected to standard speed lowcost electric motors. By simply changing the shaft rotation, pumps can be used to pump in or out through the same piping. Pump model on baseframes with motors:MC-3-SS / MC-3-SS movable Motor size:5.5 kW (7.38 HP) RPM 50 Hz:1‘450 RPM 60 Hz:1‘740 Voltage:400/440 V, 50/60 Hz, 3 ph other voltages on request...

...These planetary gears, which can only be switched in stationary mode, are available in two- or three-stage versions. The shifting is done via a hydraulic or manual shifting mechanism. Our standard shifting gears are available for a maximum torque of approximately 7,500 Nm. Due to their extremely compact design, they are primarily used for power swivel heads in drilling machines. Additionally, Rollstar is continuously developing switchable solutions for larger planetary gears, currently up to 300,000 Nm. Do not hesitate to let us know your special requirements.

...To increase the lifespan of worm gears, improve sliding properties, and enhance emergency running characteristics, the worm wheels are made from special centrifugal cast bronze. This ensures an optimal material pairing between the wheel and the shaft. The centrifugal cast blanks are also sourced from reputable subcontractors. Depending on the requirements, other materials for the worm wheel are also used, such as special brass or spheroidal graphite cast iron, which is further subjected to surface treatment after machining.

...Complete internal gearing; With a segment; Or tooth by tooth manufacturable Internal gears are usually produced using impact tools. These can be used in various designs. For example, the complete internal gearing, just a segment, or tooth by tooth can be ground. The tools can also be designed with one or more pre-cutters. In all variants, it is possible to manufacture the profile with or without overlap. Item: 308...

...Flame hardening, induction hardening, and laser hardening are the three most common surface hardening processes. For decades, they have been widely used at Gerster AG. The successful company history began in 1950 with flame hardening. Subsequently, the machinery was gradually expanded to the current 50 surface hardening systems. Over the years, our specialists have developed very specific expertise, allowing them to offer you the optimal surface hardening solution for every need today. Today, surface hardening is primarily applied in drive technology for gears and guides.

...The BS series worm gears feature a symmetrical, compact aluminum die-cast housing. They can be used as actual gears or as gear motors. These units have been successfully used for many years under various harsh environmental conditions. For use in aggressive environments, where normally only stainless steel drives are accepted, we offer the BS series gears with an additional, special surface...
