The BAC brake lining is a woven lining of ceramic yarns with very thin monofilaments reinforced with brass wire. The wire acts as mechanical reinforcement and a medium carrying off heat from theworking area. Special multi-layered weave prevents delamination of lining under high loads while braking. Such a woven lining is soaked with top quality composition of natural and synthetic resins, which results in manufacturing a reliable and highly homogeneous friction material.
Woven brake lining BAC: Application
The BAC woven asbestos-free brake lining is designed for application in drum brakes of heavy machinery, wherever large braking forces are essential, at high temperatures and in places where high reliability of friction material is required.
Technical characteristics:
Acceptable working parameters of the woven brake lining BAC:
- Maximum unit pressure for lining adhesion to brake raceway: 1,2 MPa
- Maximum tangential velocity of braking raceway 20 m/s
- Maximum temperature under continuous operation 280°C/350°C *
- Minimum kinetic friction coefficient 0,40
Technical specification for application of hoisting machines in mining industry:
Acceptable working parameters of the woven brake lining BAC:
- Maximum unit pressure for lining adhesion to brake raceway 0,8 MPa
- Maximum continuous working temperature for tangential velocity of friction surface 16 m/s 150℃
- Maximum continuous working temperature for tangential velocity of friction surface 26 m/s 100℃
- Minimum kinetic friction coefficient 0,40
Caution:
In order to evaluate the temperature correctly not only the ambient temperature in which the brake lining is assembled, but also the growth of temperature due to friction heat emission in working area should be taken into account. In case of intense braking the temperature can increase by as much as 200 ℃.
Approvals and admissions:
BAC brake lining posseses admission no. GM-15/12, issued by Polish State Mining Authority (WUG) for application in hoisting machines used in mine shaft hoists. Brake lining BAC is also certified by Germanischer Lloyd.
