Product Specification

Self-Lubricating Graphite Plugged Oilless Die Bushings are specialized components designed for applications that require a bearing solution without the need for external lubrication. These bushings utilize graphite, a natural mineral with excellent self-lubricating properties, to provide smooth, wear-resistant operation without the use of oil or grease.

The graphite plugs are embedded within the bushing material, typically a metal alloy, to create a wear-resistant surface that can withstand high loads and temperatures. The graphite acts as a natural lubricant, reducing friction and wear, while the metal alloy provides structural strength and dimensional stability.

Self-Lubricating Graphite Plugged Oilless Die Bushings are commonly used in applications where oil or grease lubrication is not practical or desired, such as in high-temperature environments or in applications where contamination from lubricants could be problematic. They are also suitable for applications requiring frequent maintenance-free operation or where lubrication systems are difficult to implement.

These bushings are often used in die casting machines, presses, and other industrial equipment where precision alignment and smooth operation are critical. Their self-lubricating properties eliminate the need for periodic relubrication, reducing maintenance requirements and downtime.

In summary, Self-Lubricating Graphite Plugged Oilless Die Bushings offer a reliable, maintenance-free bearing solution for applications requiring smooth, wear-resistant operation without the use of external lubricants.

Applications

• Place where lubrication cannot be applied or lubrication is dangerous.
• Place where product can be contaminated or failure is occurred due to lubrication.
• Low / High temperature, under-water, and place that is exposed to chemicals.
• Place that can prevent decrease in productivity due to machine stop while lubricating.
• Place where oiling is not effective due to harsh conditions such as frequent stop motion.
• Impact and vibration, high-load low-speed motion, rust occurrence, foreign substance penetration.
• Sliding motion, angular pitching motion.

Characteristics

• Can achieve excellent performance in high-load and low-speed motion, while lubrication is not applied.
• Can achieve excellent abrasion resistance in an environment where lubrication film is difficult to be formed such as
reciprocating motion, angular pitching motion, and frequent stop motion.
• Can be used in a condition where tolerance is not precise or working condition is rough.
• Relatively resistant to inflow of foreign substance, corrosive and chemical environment.
• Standards parts and custom-made parts available.
