Plug Graphite Bearings
Plug Graphite Bearings
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.
Enduralube ™ Bearings from National Bronze Mfg are commonly used in applications requiring a completely self lubricating, copper base alloy bearing material. Choose from our many standard sleeve and flanged bearings, in both metric and imperial sizes, or let us produce a custom part to your exact specifications. The National Enduralube bearing requires no oil or grease, instead a graphite film is formed between the surfaces to provide a reliable, mechanical barrier of lubrication. Additional capabilities include graphite filled grooves and wear plates. National Enduralube Bearings can be manufactured from a number of bronze alloys to meet the specific requirements of your application

Totally Self-Lubricating: No oil or grease required.
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: -415° ° to 1,100° °F
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.
