| Cast Bronze Bushings |
| |
| Cast bronze bushings is based on high strength brass or other material based on your choice, lubricating by oil added in the oil grooves. This type cast bronze sleeve bushing has the same performance with other oiles bearing.but with much higher hardness, twice life time for low speed application compared with tin bronze bushing. It's also called cast bearing,brass bush,cooper bearing,solid sliding bearing,oil grooves plain bearing,cast bronze bearing, cast bronze and so on. |

| FR Bronze MeshBearings/ Strip |
| |
| FR Bronze MeshBearings ?is a bearing made ofbronze mesh, PTFE infused fixable liner material designed to make assembly easy and effective. The material handles a wide torque range, and is intended for lower speed and light load applications. |
| |
| DB Cast Bronze Bushings |
| |
| DB Cast Bronze Bushings is made of Cast Bronze Bushings with Solid Lubricant Inserts, the base metal withstands high load and the graphite provide self-lubrication. This type of oiles bearing shows excellent performance without pre-lubrication under conditions of extreme high/low temperature with low speed. DB Cast Bronze Bushings provide a maintenance free bearing solution, particularly for high load, intermittent of oscillating motion. |

| Bimetal Plain Bearings |
| |
| Bimetal Bearings SAE 792 CuPb10Sn10 with indents is a bearing composed of two metal strips, in two different materials; The first is normally in steel backed with low friction and excellent wear resistance. The second is normally constituted by an alloycontaining copper, which when coupled with the steel strip acts as aninternal covering. Furthermore, some bearing bushings also have an external relubrication hole. the designed oil pockets, grooves and holes aresuitable for lubricated application to improvethe PV value. |

| Metal-Polymer Bronze Bearings |
| |
| Metal-Polymer Bronze Bearings PTFE + Lead is a type of composite oilless bearing, it has a common structure, consisting of a bronze backing bonded to a porous bronze sinter layer impregnated and overlaid with the PTFE/lead bearing material. Metal-Polymer Bronze Bearings PTFE + Lead take advantage of the out-standing dry bearing properties of PTFE and combines them with strength, stability and good wear resistance, excellent heat conductivity and low thermal expansion. It's also called teflon bearing,and PTFE lined dry sliding bearing, oil free bushes. |

| Metal-Polymer POM Bearings |
| |
| Metal-Polymer POM Bearings is a boundary self lubricating bearing, this type sliding bearing has similar material structure with PEEK bearing. It's also called DX bushing, POM based self lubricating bearing,plain dry bushing and POM oilless bearing. |
| |
| Sintered Bronze Bearings |
| |
| Sintered Bronze Bearings is made of tin bronze powder mutallurgy, the bearing byincreasing the porosity, oil containing rate be improved; it is long life because of high oil content, and abolition the oil filling felt, therefore, the total production cost reduced.With the boundary lubrication characteristics of sintered metal self-lubricating bearings, this kind of impregnated oil can take the partial high contact pressure and harsh alternating shear, forming the strong adsorption oil film on the contact surface regularly and small shear strength. Meanwhile, the oil subjected to thermal shock conditions, it is difficult or can not to occur the thermal damage( oxidation, decomposition and overlap ), with high thermal stability also. |

| Sintered Iron Bearings |
| |
| Sintered iron bearings is a bearing made of iron powder metallurgy, by the processing of powder mixing, compacting, sintering, oil-impregnating. |
| - Maintenance-free bearing for general engineering applications
- Optimum performance under relatively light loads and high speeds
- Produced by powder metallurgy process and therefore suitable for complex shapes
