How it works

• When the shaft rotates, heat and pressure draw oil out of the pores to lubricate the surface.
• When the machine stops, the oil is reabsorbed back into the bush.
• That’s why it’s called self-lubricating—no regular greasing needed.

Key advantages

• Low maintenance (no frequent lubrication)
• Quiet operation
• Good for continuous use
• Resistant to wear
• Cost-effective for many applications

Typical uses

• Electric motors
• Fans and blowers
• Small gearboxes
• Household appliances
• Light machinery

Limitations (important)

• Not ideal for very high loads or shock loads
• Limited performance at very high speeds or temperatures
• Needs proper shaft finish and alignment to last
