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.

Dispensers with a steel bowl are more durable than dispensers with a plastic bowl, so they’re the better choice if there's vibration or impact.
