Super Lube 21030 Multi-Purpose Synthetic Grease with Syncolon, 3 oz Tube

Super Lube 21030 is the 3 oz tube of Super Lube Multi-Purpose Synthetic Grease with Syncolon®, the brand’s general-purpose grease and the size most home shops, mechanics and makers keep on the bench. Synthetic base fluids carry Syncolon (Super Lube’s PTFE) micro powders, which protect against friction, wear, rust and corrosion. It is an NLGI 2 grease rated -45°F to 450°F (-43°C to 232°C), registered NSF H1 for incidental food contact, and it contains no silicone.

• Passes a 100-hour salt spray test (ASTM B117); dielectric strength 643 V/mil

Where to use it

Plain, ball, roller and wheel bearings; cams, slides, valves, conveyors and chains; hubs, axles, shocks, springs, seat tracks and fifth wheels; winches, pulleys, garage doors, lawn mowers, snow blowers, sewing machines, faucets and pool pumps; bicycles, guns and fishing gear. If you maintain a 3D printer, a PTFE grease of this type is a common choice for linear rails and lead screws; check your printer maker’s guide first, since some specify a particular lubricant. See our 3D printer lubricant picks.

How to use

1. Clean and dry the area or part.
2. Purge any other grease before switching, as Super Lube recommends.
3. On bearings, wipe the grease fitting clean, fill the bearing about 1/3 to 1/2 full and do not over-grease; excess grease causes heat.
4. Monitor the part, set a regular maintenance interval, and periodically clean and repack bearings with fresh grease.

Compatibility and cautions

Super Lube describes the grease as compatible with most other greases. It is not for use in a pure oxygen environment. Read the SDS before use.

Choosing between 21030 and other Super Lube greases

The same grease is sold as a ½ oz 21010 tube, a 3 oz 21036 cartridge for mini grease guns, a 14.1 oz 41150 cartridge and a 14.1 oz 41160 canister. Buying for several benches or vehicles? The 21030 3-pack keeps spares on hand. If the parts are plastic or rubber, such as plastic gears, sealing rings or anything that squeaks, choose Super Lube 92003 Silicone Lubricating Grease, which is silicone-based and rated -40°F to 500°F (-40°C to 260°C).
