Cartridge for automatic lubricator

Automatic lubricator cartridges are pre-filled replacement reservoirs for automatic grease lubricators (grease lubricators) that dispense a set quantity of lubricant to bearings and other points. The drive unit of the lubricator body (such as an electric type) pushes lubricant out of the cartridge and supplies small amounts over a set period. When the cartridge is empty, only the cartridge is replaced and operation continues. Capacities listed for these products range from 125 to 380 ml, and both grease-filled and oil-filled versions are available. They are used for lubrication of conveyor bearings, packaging machines, bottling machines, and other points where manual greasing is labor-intensive or where access is difficult.

How to choose Cartridge for automatic lubricator

  1. 1. Select a cartridge compatible with the lubricator in use

    Cartridges are generally shaped and connected for specific lubricator models or series, and other models typically cannot be fitted. First confirm that the model of your lubricator matches the series name listed under compatible lubricators in the specifications.

  2. 2. Determine capacity from greasing quantity and replacement interval

    Capacities listed for these products range from 125 to 380 ml. Where the same lubricator has different capacity options, select by working back from the required discharge quantity and desired replacement interval. Larger capacities reduce how often replacement is needed, but confirm the capacity range the lubricator can accept.

  3. 3. Check the lubricant type suitable for the bearing

    Choose grease or oil according to the structure of the lubrication point and the lubrication method. Mixing lubricants of different types can reduce performance, so confirm that the filled product is compatible with the lubricant currently in use.

  4. 4. Match the grease brand and consistency

    Grease compatibility varies with thickener and base oil, and mixing different brands should generally be avoided. The NLGI consistency number indicates hardness grade; a smaller number means softer grease that is easier to dispense. Verify against the brand and consistency specified by the equipment manufacturer.

  5. 5. Confirm suitability for the ambient temperature

    Lubricant becomes stiff at low temperatures and becomes difficult to dispense, while at high temperatures it softens and degrades faster. For outdoor equipment or use near refrigeration or heating processes, confirm that the operating temperature range includes the ambient temperature at the installation site.
