TBM(Tunnel Boring Machine) slewing bearings

We committed to exploring slewing bearings over the years,

SBI can produce slewing bearings with diameters from 100mm ~ 6000mm,

Each set of product have the traceability ,

Our testing center by the CANS international certification,

We can guarantee high -quality test of each bearing products.

SBI has a significant progress in TBM''s main bearing !

SBI and Shanghai Tunnel Engineering Co., Ltd. continued cooperation to findings TBM main bearing for many years since.

We studied different soil layer structure and bearing''s stress analysis and load distribution and contact stress and fatigue life analysis,

We have a unique design theory,

The retainer having a low friction coefficient and wear resistance,

Because of the Aluminum bronze cage is overall structure with There are film-oriented wedge angle .

And each rolling have distribution load , because of Logarithmic curve rollings.

This improves the load carrying capacity and life of the bearing.

Our bearings run perfectly in TBM,

SBI TBM slewing bearings have more lifetime value than other products.

SBI TBM slewing bearings are used in China''s largest Tunnel Boring Machine,

SBI TBM slewing bearings can replace the bearing of other countries,

You can reduce the manufacturing cost of the TBM if you are using SBI slewing bearings.

The partnership with famous largest corporations of Top 500(ABB、EMERSON、IHI、FMC、CARGOTEC、TEREX...) is very favourable for us to improve overall quality and management.

Finally, thank you for your interest in our products and services!
