N1 is a one-piece, single-acting sealing element and is available in NBR and polyurethane (TPU). U-cup seals are active sealing elements and as the system pressure increases, the force on the sealing lips also increases.
The U-cup N1 has a symmetrical profile and is particularly suitable for hydraulic and pneumatic applications. NBR seals are used as primary seals for system pressures up to 15 MPa. U-cup seals made of TPU are suitable for working pressures up to 40 MPa. TPU makes these seals suitable as primary and secondary seals due to the excellent abrasion resistance.
The standard TPU compound has a hardness of 93 Shore A. NBR U-cups have a hardness of 90 Shore A. Compounds in a different hardness and/or color are available upon request.

Our Logistics – Your Service
Innovative, environmentally friendly and efficient
In addition to innovative techniques, our logistics has 2,870 sqm of process surface. We have the world's first AutoStore storage system on two levels. Both grits are connected to each other by means of special lifters. In total, up to 31,000 containers can be stored in a very confined space. Due to this subdivision, up to 240,000 storage areas can be managed most efficiently.
