The BDL 32012 tapered roller bearing is engineered for heavy axial-radial load combinations, featuring:
Parâmetro | BDL 32012 | Rolamentos cónicos standard |
---|---|---|
Diâmetro interno | 60 mm | 50-70 mm |
Diâmetro exterior | 95 mm | 80-110 mm |
Capacidade de carga dinâmica | 112 kN | 90-105 kN |
Temperatura de funcionamento | -30°C a +120°C | -20°C a +100°C |
Superior lubrication retention design reduces maintenance frequency by 40% compared to conventional models[4][8].
Critical roles in water infrastructure:
Withstands variable loads from water pressure fluctuations (up to 15 MPa)[1][10].
Aplicação | Tipo de carga | Benefício de desempenho |
---|---|---|
Hydro-generators | Combined radial/axial | 99.3% uptime over 5-year period |
Water pumps | High-speed rotation | 30% vida útil mais longa |
