Overview
Constant level oilers provide automatic regulation of oil level inside bearing housings and similar enclosures. They maintain a preset oil height to ensure continuous lubrication of rolling element bearings, reducing operator intervention and preventing damage caused by low or uneven lubrication.

How do constant level oilers work?
The device keeps a fixed oil level by allowing oil to flow from a reservoir into the sump when the level falls below the set point. Operation relies on gravity and pressure balance; the unit replenishes oil automatically as long as the reservoir contains fluid.

Key features

• Automatic maintenance of a constant oil level
• Designed for rolling bearings and similar housings
• Reduces manual oil checks and maintenance actions
• Minimises risk of bearing failure due to oil loss or under-lubrication
• Available in multiple reservoir materials (plastic, glass) and sizes
• Standard thread options: BSP and NPT

Applications and compatibility
Commonly used in heavy industry, chemical and process plants, and other environments where reliable, continuous lubrication is required. Select reservoir material and capacity based on temperature, chemical compatibility and refill intervals. Typical capacities range from 85 cc to 500 cc.

FAQ

• Q: What is the primary purpose of a constant level oiler? A: To automatically maintain a set oil level in machinery housings, ensuring consistent lubrication of bearings and reducing the risk of damage from insufficient oil.
• Q: Are these oilers suitable for high temperatures? A: Many models, especially with glass reservoirs, tolerate elevated temperatures. Verify the product temperature rating for specific applications.
• Q: Which connection types are available? A: BSP and NPT threaded connections are commonly offered to match industrial plumbing standards.
• Q: How often must the reservoir be refilled? A: Refill frequency depends on consumption and reservoir capacity; the system only needs manual refill when the reservoir runs low.
• Q: Can they be used on all machinery? A: They are ideal for applications requiring a fixed oil level (e.g., rolling bearings) but suitability should be evaluated per equipment lubrication needs.
