Graphite plugged oiles bearing is made of cast bronze alloy base material with special solid lubricants plugged. 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. JDB graphite plugged oiles bearing provide a maintenance free bearing solution, particularly for high load, intermittent of oscillating motion.

Cast Bronze Bearing with Graphite Plugs

Characteristics


TOB-50 Flange

1. May work without any ol for long period

2. Extremely high load capacity, good anti-wear and lower friction

3. Particularly appropriate for low speed and high load

4. Suitable for reciprocating, oscillation or intermittent motion where oil film is hard to be formed

5. Good chemical resistant and anti-corrosion characteristics

6. Can b€ used in wide range of temperature from -40℃-+300℃

Strusture

TOB-50 Flange material is made of strong cast bronze based metal with special solid lubricants embedded. The base metal withstands high load and the solid lubricants provide self-lubrication. The bearing shows excellent performance without pre-lubrication under conditions of extreme high/low temperature with low speed. This material provides a maintenance-free bearing solution, particularly for high load, intermittent of oscillating motion.

Material

Solid Bronze bushings and plates are made completely of tin bronze, CuSn10P, which has very good machine ability. All surfaces of the solid bronze bushings are machined.

Solid iron bushings and plates are made in same way of bronze material, but it is much lower costs if you are not in high performance requirements.

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.

Dry lubricated bearings

TOP bearings incorporate graphite and molybdenum disulphide as the dry lubricants. In these materials, the lubricating properties are the consequence of a lamella layer structure that is created under load, when the lubricant adheres to the contact surfaces in the bearing. The layered structure enables sliding movement of the parallel plates . Weak bonding between the plates provides low shear strength in the direction of the sliding movement but high compression strength in the direction perpendicular to the sliding movement. Also, a solid lubricant having high compression strength is capable of withstanding heavy loads without creating metal-to-metal contact. Finally, the dry lubricant has good adhesion to the substrate surface. This property provides a presence of solid lubricant on the bearing surfaces even at high shear stresses.

Typical Application

This kind of bearing can be applied under dry, high temperature, high pressure, corrosive, water or other chemical environments when no oil can be introduced. It is widely used in automotive products line, water engineering, dam gate, plastic industries, successive casting machines, steel rollers in metallurgy industry, mineral machines, ships, turbo generators, hydraulic turbines and injection molding machines...

Customer Size Oem & Odm Bronze Bushing

It is based on high strength copper alloy of special techniques. The solid lubricant is inlayed by certain angle, density and special formula, and then is processed exactly. The product is widely applied to casting machine, mining machinery, shipping, steam turbine, Injection machinery and automobile mounding, etc.
