TCB40 Classification

TCB 401

TCB401 sintered bronze powder bushing is mold pressed under high pressure and then sintered under high temperature, and oil is soaked into the homogeneously spreaded tiny pores of the metal under vacuum. This bearing can withstand dry condition in medium speed and low load for short time...

TCB 402

TCB402 sintered iron powder bearings can protect shaft with oil. They're anti-friction same as bronze powder bearings under low load. They're widely used in textile machines, electric tools and absorbers of auto and motorcycle. When being static, hey can be acted as orientation bushing.
