Extreme High Temperature Application
Extreme temperature formulation and processing of Cobra Solid Lubricants is available for applications with continuous operating temperatures between 450°F and 660°F. This special formulation is ideal for use in furnaces, conveyor ovens, kilns, hot air blowers, flue dampers, etc. Specify standard steel bearings for maximum load and speed where corrosion is not an issue. Designation: 204-12-T (ss) or 204-12F-T (steel).

High Temperature Application
High temperature formulation and processing of Cobra Solid Lubricants are capable of continuous operating temperatures between 250°F and 450°F on high tension or high speed shafts. The lubricant will not drip or fling and area contamination due to leakage is eliminated. Designation: 204-12-M (ss) or 204-12F-M (steel).

Normal Temperature Application
When operations require low friction or free-spinning bearings in a dirty or dusty location. Designation: 204-12-W.

Very Low Temperature Application
Bearings involving high speed or high tension maintain constant low starting torque even with temperatures in the cryogenic range with Cobra Solid Lubricants. The efficiency achieved results in longer motor life plus energy cost savings: 205-16-B (ss).

Submerged applications
Cobra Solid Lubricants are not soluble in most common solvents, acids, or alkalis. They are the ideal lubricants for bearings used in pumps that would wash a conventional lubricant out. Chemical or steam cleaning involving high speed or high tension can be accommodated with Cobra bearings. (Cobra bearings are better in fully submerged locations than those that are intermittently wet and dry.)

Limited Accessibility
Cobra Solid Lubricants are the perfect choice for locations where ball bearings are required but relubrication is difficult.

Cautions

Maximum Operating Temperature for H2000
Maximum Continuous: 82°C (180°F )
Maximum Interim Heat: 93°C (200°F)

Load Rating
When lubricated with H2000, bearing load ratings are the same as for standard bearings.

Speed: NDM Maximums
To determine whether your bearings fall in the allowable maximum speed limit range that is suitable for H2000, use this formula:

NDM=(O.D.+Bore)in mm X RPM
2

• H2000F Food Grade for Higher RPMs
• H2000FW Food Grade for Higher RPMs with sealing additive (for wet applications)
• Designation: 204-12-J (400 series ss)
           or       204-12-3J (300-series ss)

Since H2000 is a solid lubricant, seals and shields in most applications are not necessary but can be used to help keep dirt out. Seals can be replaced if requested; but shields cannot.
