Mechanical engineering is one of the leading industrial sectors, one where further development never ceases. Technology, expertise, the art of engineering – mechanical engineering is known for all of those. This is a sector spanning a vast and diverse range of applications, from drive technology to workpiece machining, production and quality control, from metal to wood or plastic.

Seals and technical parts play an important role in mechanical engineering from specific machinery and plant to their upstream and downstream peripherals. The name SCHLÖSSER is a guarantor of quality and versatility. Our technical parts also embody total quality, they are Made in Germany and they are often the outcome of high-end engineering processes.


Quite simply, technical parts made by SCHLÖSSER can be used in very many mechanical engineering contexts. We field a wide range of standard products, and our team of technical experts can also tackle specialised requirements flexibly and rapidly. This is what makes us a top manufacturer and supplier on the mechanical engineering sector.

TECHNICAL PARTS made by SCHLÖSSER are used in:

Dichtungen Schlösser Elektromotoren

industrial electric motors

The custom seal solutions we offer enable us to keep pace with the extremely demanding requirements in electrical drivelines. Our high-quality products ensure that we can assure extended service lives and greater machine reliability coupled with lower friction losses and performance impairment.

Dichtungen Schlösser Maschinenbau


Seal integrity, reliability and efficiency are crucial factors in the drive technology sector.

In addition to assembly errors, corrosion and progressive leakage constitute potential hazards here, especially with gearbox motors that are often in operation over extended periods of time. Technical parts made by Schlösser are therefore, quite simply, indispensable.

Dichtungen Schlösser Hydraulik Pneumatik

Hydraulics & pneumatics

The choice of precisely the right seal to achieve optimum functionality for your hydraulic or pneumatic cylinders depends on three things. You need to have a comprehensive overview of operating conditions, movement sequences and the interaction of all components involved. As well as the primary seal function, the correct choice of material, physical performance in relation to operating temperature and operating pressure and an understanding of the properties required all combine to assure low friction losses and good resistance to abrasive wear. We are able to provide you with an optimum solution in terms of quality and cost-effectiveness because we can access a comprehensive material portfolio sourced from renowned suppliers, we have a range of high-performance machines and we employ a very capable team of highly skilled experts and specialists. The name SCHLÖSSER is a byword for the very finest quality of technical parts made from plastic – today and into the future.

Pumps and vacuum technology

Reliability is the key to achieving cost-effectiveness with any process technology system. Seals have an important role to play in reducing plant downtime and the associated loss of production. For example, they can ensure that liquids remain sealed in a container where shafts rotate in stationary housings, or occasionally where housings rotate around a stationary shaft.

Proper sealing also delivers significant benefits in terms of operational safety and the service life of a pump.

In vacuum technology, seals are used to prevent the ingress of ambient air into the vacuum. Depending on application and pressure range, various designs of seals are available.

Dichtungen Schlösser Laborausrüstung


The performance capability in the robotics sector is increasing progressively and new fields of application are getting added all the time. As a component in automated and digitally networked production and logistics systems, reliable functional integrity is an essential requirement. Thanks to the specific choice of material and component designs that are perfectly matched to each application, ultimate standards of functionality can be achieved consistently. Our sealing solutions can withstand big fluctuations in temperature and high speeds. This enables them to improve cost-effectiveness by a substantial amount. Added to this, our seals can prevent leakage and resultant malfunctions. This in turn eliminates downtime and its associated costs.

Industrial lift trucks

Movement and continuous operation cause wear and tear on many components associated with industrial lift truck technology.

Pallet trucks and forklifts are good examples, engaged in constant movement at high pressure which, as time goes by, leads to problems with the raising and lowering of forklift tines or with oil loss. Which in turn entails the need for regular maintenance.

Although for the most part invisible, but no less essential for that, our solutions contribute in many ways towards satisfying the quality demands of intralogistics while at the same time minimising or even preventing extended periods of equipment downtime.


For the most part, companies that operate on the mechanical engineering sector move within the boundaries of high-end delivery chains: These are defined not only by ultimate standards of quality but also by absolute deadline compliance. Here, SCHLÖSSER constitute the ideal components. Firstly, we provide high-quality products and secondly, our delivery performance is exemplary thanks to our high inventory capacities. Our experienced team is also delighted to assist with one-off production runs and the development of prototypes. With our clean room production facilities, we can also manufacture products for particularly sensitive sectors.
