LUBESITE 502 Corrosion Resistant Grease Feeder, 1 oz. Capacity, 1/4 Inch NPT

LubeSite 502 grease feeder is designed for lubricating reservoirs that are mounted on machines and equipment to automatically dispense grease into critical moving components. This process eliminates the need for manual checks and prevents machine failure due to over-or-under greasing.

Features:

• Features a nickel-chrome, double plated base for protection against corrosion in chemical and food processing applications.
• Utilises Venturi mechanism to discharge the lubricant only when the bearing is in motion.
• Equipped with meter rods featuring graduated channels to regulate the flow of grease as needed.
• Provides 1 - 5 PSI spring tension to prevent blowing of bearing seals.
• Utilises NLGI grade 0 to 4 non-separating grease that can withstand operating temperatures ranging from -10 to 250 degrees F.

Compatible Accessories:

• Lubesite Remote Refill Kit: These refill kits are utilised with this grease feeder to refill the grease from distances up to 3 meters.

Frequently Asked Questions:

Q. How do I select the proper spring size?

A.

• To determine the size, a user may need the bearing shaft diameter and speed along with the bearing class. For example, if the shaft diameter is 2 inches and shaft speed is 2000 rpm, a larger spring unit is required.
• The user also needs to know the operating temperature and grease weight. For example, if the operating temperature of the bearings ranges from 60 to 80 degrees F, and a Grade 2 grease is used as a lubricant, then a medium spring assembly (silver) is needed.

Q. What are the applications of the 500 Series grease feeder?

A. 500 Series grease feeders are used in any equipment that has anti-friction oscillating, ball / roller bearings, shielded bearings with seals, bronze bearings and more.

Q. What are the factors to select springs according to application requirements?

A. The spring selection depends on the temperature and grease weight. Units are colour coded for use in different applications, such as blue for light, silver for medium, red for heavy and orange for very heavy duty applications.
