DeutschSolid Lubricated Brass Bearing
The #50SP5-SL1 solid lubricated brass bearing is primarily composed of high-strength special brass with HB>235. Its wear-resistant surface has a certain proportion of drilled holes. This kind of oil-free brass bearing is inset with a solid lubricant. Both its strength and hardness are higher than those of the #50 SP1-SL1.
Characteristics
1. Owing to higher mechanical strength and hardness, the solid lubricated brass bearing is provided with increased carrying capacity and abrasion resistance in comparison with #50SP1.
2. It can be applied in different industries such as mining machinery and engineering machinery.
3. The engineering machine bearing gives superb wear resistance under conditions of low speed and heavy load.
4. It is not suitable for use in seawater environment.
