Couplings Description

The ESCOGEAR N series couplings are lubricated type couplings with the highest torque capacity. The ESCOGEAR N series couplings basically consist of two hubs with external teeth connected by means of one single internally geared sleeve and sealed by two flanges. This is a light version of the ESCOGEAR F series couplings.

The couplings are able to compensate for radial, angular and axial misalignments. Where the angular misalignment is determined by the gearing geometry, the axial capacity varies according to the manufacturer and can be great.

They have a small backlash and allows smooth running over the entire speed and torque range. Grease lubrication ensures low maintenance and at the same time allows relatively large shaft misalignment.

Couplings Construction

Couplings Fields of Use

ESCOGEAR N series shaft couplings are designed for economical drive in all industries.

They are used mainly in the drives of conveyor systems, rolling mills and other drives in steel mills, in the paper, chemical and rubber industries.

The modular system offers maximum flexibility in assembling various configurations. The couplings are available in various sizes and designs.

Couplings Material

The ESCOGEAR N series couplings are generally made out of carbon steel Ck45 and the flanges of stamped steel.

Couplings Advantages

  • Maximum bores defined by standardized shaft diameters
  • Reduced external dimensions and weight
  • Easy installation and minimum maintenance requirements
  • Absolute reliability
  • Perfect homokinetic torque transmission
