• Improved cooling performance
• Reduced friction and wear
• Extended bearing life

Large Oil Sump Design

• Large oil reservoir integrated into the base
• Ensures continuous oil supply during operation
• Suitable for prolonged industrial duty cycles

External Circulating Oil Lubrication System (Optional)

For applications involving extremely high operating temperatures, SOFN housings can be equipped with an external circulating oil lubrication system.

System Includes

• External oil pump
• Filters and control valves
• Heat exchanger
• Oil circulation piping

Advantages

• Precise temperature control
• Continuous oil cleaning and cooling
• Improved lubrication efficiency
• Increased bearing reliability

This system is recommended where bearing temperatures exceed standard operating limits.
