Seals

All standard ball bearings of Nanotec motors have an integrated ZZ seal which, together with the shoulder of the inner bearing, forms an active gap seal and makes it difficult for dirt particles to penetrate and prevents emergence of the lubricant. The cover plates are made of non rusting steel and do not cause any increase in torque or have any influence on the highest admissible speed compared to open ball bearings.

For greater sealing requirements, the material selection regarding chemical resistance, high and low temperatures, low and high contact pressure and circumferential speed, vacuum, Rockwell hardness, special coatings with regard to FDA conformity for beverage and foodstuff applications etc. is decisive.

Whereas the most different forms and constructions, such as special lip profiles for the optimization of driving forces, O-rings with different tolerance classes and cross-section diameter, radial seals, radial shaft sealing rings, face seal, V-rings with chamfered sealing lip, elastically supported PTFE seals (with highly stress-resistant plastic compound and an embedded spring of corrosion-proof stainless steel), as well as also RS, 2RS seals, VS seals, RZ seals are specified by the respective applications.
Through the integrated sealing construction, together with our customers we can realize a wide variety of different sealing solutions with even the smallest clearances.

Customer-specific seals are economically possible from an order quantity of 50 pieces.
