IRE-OMBA was founded in 1906 by the Earls of Sottocasa under the name
“SOCIETA’ ANONIMA OFFICINE METALLURGICHE SOTTOCASA”. Its headquarters
were at No. 14, Via Serassi Bergamo.
In 1932, the company changed its name to “Officine Metallurgiche Bergamasche
Anonima” (OMBA).Up until the early 1960s, the factory in Bergamo manufactured large-scale forged
pieces weighing up to 6,000 kg: drive shafts, piston rods, cylinder heads for large
marine engines, and large round and flat forged sections. In the die-casting field,
the company at this time specialized in a range of products for the engineering,
automotive and petrochemical industries.
It was towards the end of the 1960s that OMBA made forging the sole focus of
the company, speciali zing in the production of rings.

The first ring rolling mill was installed in 1969 and remained in operation
until 1997.
In 1974, the product range was increased with a new rolling mill, to which
two hydraulic presses were added in 1975 and 1976.
This equipment – albeit revamped – is still in use today.The late 1980s saw the start of a period of radical renewal, both in terms of
production and in terms of the organizational infrastructure of the company,
which gradually evolved from a family business to a more corporate concern
– a change that has allowed OMBA to continue its expansion.
With plants in Bergamo and Seriate, and a manufacturing facility about to
open its doors in China, OMBA has now consolidated its position as a key
manufacturing company in its sector at international level among the top ten
worldwide rings producers.
OMBA TODAY.

all OMBA products, each part undergoes a series of

• Non-destructive testing (ultrasonic, magnetic particle,
liquid penetrant)

Everyone makes mistakes. Ours never leave the factory.
