Linear drives


Whether used in cold-rolled strip, hot-rolled strip or roll forming production, material is transported to the next step in production with individually driven rollers. When a roller drive fails, the remaining drives have to absorb the force to continue transport. This frequently has a negative impact on the surface coating of the rollers and thus impacts the service life of the system.

It is therefore essential to prevent coupling failures on the roller drive. Since the transported material often emits temperatures of over 180°C, spider couplings are not a long-life, durable solution. Even gear couplings are not a good alternative for this application due to the maintenance required. Metal bellows couplings, however, offer a real alternative solution. In addition to their rugged design, these couplings compensate for misalignment and thermal expansion. To meet a specific operating requirement for impact resistance, they also come with an optional integrated safety system.
