P4.1 rol e-chain

Latest generation P4.1 rol e-chain®

Merging bearing technology & smart sensors for longer service life

The line of P4 energy chains has been optimized for greater reliability. With the new P4.1 roller chain, there is a bearing point for pivoting in every chain link connection. These points are integrated with maintenance-free plain bearings, which minimize friction and more than double the expected service life. Container cranes in ports, for example, can achieve a service life of more than 15 years or 20,000+ operating hours.
  • Longer service life - 375,000km running performance - due to maintenance-free tribo-polymer plain bearings in chain link connections.
  • Long travels of more than 1,000m
  • Speeds of more than 5m/s
  • Low vibration and noise thanks to split profile roller
  • Integration of sensors for predictive maintenance
  • Up to 36-month guarantee on energy chains and cables or the number of double strokes determined by the service life calculator.

Special features of the rol e-chain® P4.1

Drive power reduced

P4.1-rollers Due to the offset between upper run and lower run, the polymer rollers are not rolled over, but roll past each other to allow very smooth running. As a result, the coefficient of friction decreases and the drive power is reduced by 57 per cent.

Longer service life

P4.1-bearings Equipped with maintenance-free plain bearings in each chain link, the service life of the energy chain is more than doubled.

Predictive maintenance

Predictive maintenance As an option, the new P4.1 can be fitted with smart monitoring sensors. Therefore, at a defined wear limit, a signal is issued to the igus i. cee communication module and with it maintenance can be planned in advance.
