Inspecting a Single Point Lubricator

What is a Single-Point Lubricator?

A single-point lubricator is a device engineered to attach to a single unit to regularly and automatically deliver a small amount of clean grease or lubricating oil to a specific area. It is often used to keep bearings lubricated but can also be used to lubricate pumps, electric motors, fans, chains and conveyors, among other applications. Manually greasing bearings often result in over- and under-greasing, eventually leading to premature bearing wear. Single-point lubricators can be configured to dispense the correct lubricant quantity to a single point for a predetermined period. Single-point lubricators are a popular method of extending the life of bearings and other components and preventing extended downtime due to lubrication-related failures. While there are many types, the most common are spring-loaded, electrochemical and electromechanical.

Why use a Single-Point Lubricator?

Single-point lubricators are designed to give a consistent, measured and continuous supply of fresh grease or lubricating oil. Some applications are hard to reach, unsafe to get to or may require a lot of excess grease. You will use a single-point lubricator to add the grease more frequently than if you could do it manually. Some suitable environments for single-point lubricators include:

It's essential to select the right type of single-point lubricator for each specific environment and application to ensure optimal performance, equipment protection and cost-effectiveness.


Why inspect a Single-Point Lubricator

Inspecting a single-point lubricator is important for several reasons:

Inspecting a Single-Point Lubricator

 Step 1: Gather the appropriate tools required to perform the procedure

Step 2: Clean the outside of the single-point lubricator with a lint-free, industrial towel

Step 3: Examine the purge point and clean any purge lubricant; clean with a pipe cleaner if there is an obstruction

Step 4: Inspect the single-point lubricator

Step 5: Activate the test function to check performance

Step 6: Verify the timer is adjusted according to the correct lubrication frequency

Step 7: Check for overgreasing and make a note

Step 8: If any abnormal condition is found, report it

Step 9: Check the grease level in the single-point lubricator and report

Step 10: Note the date of the last inspection and confirm the lubricant consumption is according to the time elapsed

Step 11: Note the date and level of the current inspection

Don't forget to collect all tools used during the procedure, wipe up any spilled lubricant and dispose of all consumables used in the inspection.
