Celsa Steel Mill

Barcelona

Application:

Roller table in Steel plant

Problem:

Jaure spider type coupling (Jauflex) had persistent need for maintenance as the spider rubber had to be replaced every 3 months because of shock loads and the steel mill’s high temperatures.

Solution:

Offering 20x RBI4 FH LBIM to accommodate overall length + RBI8 Driving flange to accommodate roller shaft, Celsa enjoyed the benefits of our failsafe coupling and easy replacement of blocks

Outcome:

• Protection against shock loads and failsafe.

• No stops due to couplings failure.

Portland Valderrivas

Barcelona

Application:

Fan drives

Problem:

8x grid couplings fwere fitted to the fan drives and were causing failures because of premature wear of the steel discs. As a consequence, the company were spending too much money on replacements.

Solution:

Our experts proposed 4x RBI 4 and 4x RBI 8 as a failsafe coupling that would be able to absorb vibrations.

Outcome:

• Maintenance free

• Failsafe coupling.

Aludium

Alicante

Application:

Tension leveller and bridles retrofit at an aluminium plant.

Problem:

Shock loads can be high, damaging gear couplings teeth and gearing on drive line. They needed shock load protection coupling.

Solution:

High Speed Side:6x RBI 4 with brake disc arrangement and low speed side: 6x RBI’s with special driving flange in EN19 material to be fitted on tollok

Outcome:
