Special Plain Bearing Bush Flanged Head Self Lubricating Bronze Bushings
Brass flanged head self-lubricant inlaid bearing bushing is also known as oilless sliding bearing bushing ,do not need to apply lubricant oil during operation ,.the material is made up of brass and solid lubricant , solid lubricant is absorbed by brass bearing bushing body when bearings are put into it and lubricant will reduce friction that from bearing .
Brass flanged head self-lubricant inlaid bearing bushing is special designed for shaft bearing with light and heavy duty load .
Material
Flanged head self-lubricant inlaid bearing bushing is made of brass ZCuPb30
Technical data
| Material | ZCuPb30 |
| Hardness HRC | 25 |
| Working temperature | 300°C |
| Bearing Rotary ( sliding ) speed | 0.4m/s |
| Appling lubricant speed | 5m/s |
| Load | 100 N/mm2 |
| Friction | 0.18 |
Characteristics
Flanged head self-lubricant bearing bushings with more advantages compared to traditional bearings
Perfect Self-lubricant
Flanged head self-lubricant bearing bushings are not required extra lubricant during
operation compared to traditional bearing bushings and reduce much friction .
Heavy-duty
Harden metal material with perfect lubricant
Wear resistance
Flanged head self-lubricant bearing bushings can reduce much friction when bearings are working .
Resistant high temperature
Flanged head self-lubricant bearing bushings can work well in 300°C .
Standard Specification
Generally , specificationsr for self-lubricant sliding bearings from 12 to 50 and the length is from 8 to 80 mm .
