Product Overview
Will this fit?
Yes if you are greasing motor, pump, fan or conveyor bearings with a 1/8" NPT grease-fitting port, shaft up to 1-1/2" running under 2,500 rpm, intermittent or continuous (the 1 oz size in L713), in an environment with vibration or motion; the 300 series has an aluminum base for exactly that. Temperature −10 °F to 250 °F, grease NLGI 0–4.
What it does: a spring pushes grease at 1–5 psi, and the feeder only discharges while the shaft is turning, so a stopped machine is not over-greased and seals are not blown. No batteries, no gas cartridge, refillable through the standard fitting on top.
What is in the pack: four LubeSite 302 feeders, each with the medium (silver) spring installed and a light (blue) and heavy (red) spring in the box. This pack is priced the same as four singles; what you get is free shipping and four at a time.
Which spring: bearing at 40–110 °F with NLGI 2 grease → silver (installed). Colder with NLGI 2 → red. Above 110 °F with NLGI 2 or 3 → silver; with NLGI 4 → red. The full temperature-by-grade chart is on the LubeSite page.
Not a fit: static bearings with no vibration can use the cheaper 200 series; corrosive or washdown areas need the nickel-chrome 500 series; above 250 °F use the 704 glass-dome unit. A port other than 1/8" NPT needs an adapter; tell us the thread.
What's in the box: 4 x 302 1 OZ GREASE FEEDER METAL BASE.
