A spring delivers a constant, low-pressure flow of grease to your lubrication point, so it never runs dry. They’re best for applications with consistent temperatures, so the viscosity of the grease won’t change how quickly it flows. However, they shouldn’t be used in precision applications because the tension of the spring may change, causing the dispensing rate to change. Mount them close to the lubrication point. They have a standard grease fitting, so you can choose what grease to use, unlike prefilled dispensers. The grease fitting helps close the system to keep out dust and contaminants in dirty environments such as mills. Use grease fitting adapters to match your lubrication point.

Plastic Bowl—Clear—Dispensers with a clear plastic bowl make it easy to see how much grease is left and whether the dispenser is working properly. These dispensers come with three different adjustment springs to fit your dispensing needs.

Plastic Housing—Plastic housings are an economical choice when there's minimal vibration.

Anodized Aluminum Housing—Anodized aluminum housings withstand vibration, shock, and impact.

Nickel-Chrome-Plated Aluminum Housing—Nickel-chrome-plated aluminum housings resist corrosion better than plastic and anodized aluminum dispensers.

Remote-Mount Springs—Remote-mount springs (sold separately) provide extra pressure when using thick grease at a distance.
