Metallic self-lubricating bearing
DNB-#50               Plug graphite bearings are primarily used in applications that need continual  lubrication in hard to reach areas. Graphite is mechanically forced into the holes/ grooves under extreme pressure. A film of lubricant is transferred to the shaft as  it begins to turn. These bearings offer continuous lubrication over long periods  without maintenance.        Plug graphite bearings provide a mechanical lubrication system with graphite.  They are oilless and self lubricating. These bearings are designed for long life  without downtime.      Additional capabilities include graphite filled grooves and wear plates. Send us  a drawing or sample.Generally, we'll have a price back to you within 24 hours.       Reasons for Selecting Plug Graphite Self-Lubricating Products     1. Total Self-Lubricating: No oil or grease required
The self-lubricating features allow bearings to be used where oiling is difficult, expensive to implement, and where grease/oil cannot be used. Excellent lubrication is achieved even under high loads at low speeds.  2.  Excellent Wear Resistance:
Excellent wear resistance is achieved under severe working conditions, such as heavy load, low velocity, reciprocating, oscillating and intermittent motions where the formation of oil film is difficult.  3. Low Coefficient of Friction: 0.04 to 0.2 typical:
Self-lubrication with specially embedded solid lubricants reduces friction.  4. Wide Operating Temperature Ranges: -40 °C to +300 °C
Superior performance is exhibited under high and low temperature conditions.  5. Corrosion and Chemical Resistance:
Performance is not affected by water and caustic chemicals.  6. Designed to Exceed Your Requirements:
High precision products with close tolerances.  7. Cost Competitive:
Maintenance, replacement, and end-item downtime cost reduced due to the exceptional service life compared to similar self-lubricating products.  Process     Applications:  Steel mill & roll mill equipment  Cranes,elevators and other conveyor equipment  Cargo handing industry  Molding machine  Industry furnaces  Shipbuilding & offshore engineering  Plastic injection machine         Our solid (graphite)bushing/wear plate are provide with solid lubricants inserted in holes or grooves,these lubricants functioning as  a continously lubricating film between contact sliding surfaces and to prevent metallic contact bettween moving parts.    Tech.Data
