When to Choose Single-Point Lubricators for Your Automatic Lubrication System

Three automated single-point lubricators.

​​​In modern maintenance practices, ​​single point lubricators​​ have become a widely adopted technology in ​​automatic lubrication systems​​. Designed to lubricate a single bearing or mechanical component, these devices offer a more precise and convenient alternative to manual greasing. As industries continue to seek more efficient maintenance solutions, ​​automatic grease lubricators​​ like these are gaining popularity because of their ease of use and effectiveness. Whether in manufacturing, ​​automotive​​, or ​​heavy equipment maintenance​​, the demand for automated lubrication continues to grow, offering a reliable way to keep components running smoothly without constant manual intervention.​​

​​​Single point lubricators​​ are compact devices, typically slightly larger than a soda can, designed to lubricate one specific bearing or component. They feature built-in grease reservoirs with volumes ranging from 120 cc to 250 cc. Plastic casings​​​ ​​protect these lubricators​​​ and use either expanding gas or batteries to power the downward motion of a piston, which dispenses grease through a small orifice directly into the bearing​​. Installation is straightforward, as they can easily be screwed onto the bearing or mechanical component.​​

​​​The back pressure generated by these devices is typically between 3-5 bars, making them suitable for less demanding applications. One of the most appealing features of ​​single point lubricators​​ is the ability to pre-program lubrication intervals. These intervals can be set to deliver a precise amount of grease over a specific period, ranging from one month to as long as twelve months, allowing for consistent and accurate lubrication with minimal manual input.​​

​​​Ease of Use and Installation​​ 

​​​The small size of single point lubricators makes them incredibly easy to handle and install. Their compact design allows for quick mounting, and the built-in reservoir eliminates the need for external grease cartridges or complicated setups. Maintenance teams can quickly integrate these ​​automatic grease lubricators​​ into their maintenance routines without requiring specialized training or tools.​​ 

​​​Pre-Programmable Lubrication Intervals​​ 

​​​One of the key benefits of automatic bearing lubrication with single-point lubricators is setting lubrication intervals in advance. This allows for consistent maintenance with no frequent manual greasing. For instance, if a maintenance team wants to ensure that a bearing receives 0.3 cc of grease per day, the lubricator can be programmed delivering precise lubrication over a predetermined period of up to twelve months. This pre-programming feature ensures bearings receive the correct amount of lubricant, minimizing the risk of over-lubrication or lubricant starvation.​​ 

​​​Small Reservoir Size​​ 

​​​While single point lubricators offer many advantages, they have some limitations. One of the most notable is their small reservoir size, which limits their use to smaller bearings and less demanding applications. For larger components or systems that require more lubricant, a larger automatic greaser for heavy equipment may be needed. The typical reservoir capacity of 120 to 250 cc means that frequent refilling or replacing may be required in high-demand environments.​​ 

​​​Low Backpressure​​ 

​​​The low back pressure generated by single point lubricators, typically between 3-5 bars, limits their effectiveness in certain environments. For example, they may not be suitable for areas that experience extreme temperatures, high humidity, or excessive vibrations. In these conditions, the lubricator may struggle to deliver grease consistently, potentially leading to equipment failures. These devices may have difficulty dispensing higher viscosity greases, such as ​​NLGI 3​​, which requires more pressure to move through the system. This makes single point lubricators less suitable for applications involving ​​automatic greasers for heavy equipment​​ or in industries where thicker greases are commonly used.​​ 

​​​​​​​​When considering using single-point lubricators, maintenance professionals should evaluate the equipment’s specific needs. While these devices are ideal for certain applications, such as small bearings in relatively stable environments, they may not be appropriate for more challenging conditions. It’s important to assess factors like the size of the bearing, the viscosity of the grease required, and the environmental conditions in which the lubricator will be used.​​

​​​For industries that require lubrication in more demanding conditions, alternative ​​automatic lubrication systems​​ may be more suitable. These systems can handle higher back pressures, larger grease capacities, and more extreme environmental conditions, ensuring that equipment remains well-lubricated even in the harshest settings.​​

​​​In summary, single point lubricators offer several advantages in ​​automatic lubrication systems​​, providing consistent and reliable lubrication for small bearings and components. Their ease of use, compact design, and pre-programmable lubrication intervals make them an attractive option for maintenance teams looking to improve their lubrication practices. However, it’s crucial to consider the limitations of these devices, particularly their small reservoir size and low back pressure, when deciding whether they are the right choice for your specific application.​​

​​​Maintenance professionals should weigh the benefits and limitations of single point lubricators and ensure that the technology they choose meets the needs of their equipment and operating conditions. In environments where thicker greases or larger bearings are required, other ​​automatic grease lubricators​​ or ​​automatic greasers for heavy equipment​​ may be more appropriate.​​
