Product Information
Full details
The Morris K99 Water Resistant Marine Boat Grease is designed for industrial and marine environments where water exposure is a significant concern. It offers robust lubrication and superior corrosion protection for plain and antifriction bearings, even in very wet or temporarily submerged conditions. A key benefit is its excellent sealing properties, preventing contaminants from entering bearings. However, users must ensure compatibility with previously applied greases before initial use.

FAQs
What types of bearings is K99 suitable for?
K99 is suitable for both plain bearings and antifriction (rolling element) bearings, including ball and roller bearings.
Can K99 be used in completely submerged applications?
Yes, K99 is designed for applications where bearings may be temporarily immersed in water, offering protection during such periods.
How do I check compatibility with my existing grease?
A simple test involves mixing a small amount of K99 with the old grease. If they remain smooth and homogenous, they are likely compatible. If they become lumpy, separate, or change texture drastically, they are incompatible.
What is the recommended application quantity?
It is best to follow the bearing manufacturer's specific recommendations for grease quantity. As a general rule, avoid over-lubricating, as this can generate heat and reduce lubricant efficiency.
Where can K99 be used besides marine applications?
K99 is also ideal for any industrial setting where components are exposed to high humidity, frequent washdowns, or potential water spray, such as in food processing plants (where food grade is not specified), agricultural machinery, or outdoor equipment.
What does the performance level DIN 51502 K2/3G-20 mean?
This indicates K99 is a lubricating grease (K), with a NLGI consistency of 2 or 3 (depending on formulation, typically 2 for marine), suitable for operating temperatures (G), and has a base oil viscosity that provides adequate lubrication in its temperature range (-20°C to +120°C typical for this rating).
Is K99 a high-temperature grease?
K99 is formulated for water resistance and corrosion protection. While it has a typical operating temperature range, it is not specifically designated as a high-temperature grease. For extremely high-temperature applications, consult the Morris Lubricants technical data sheets for alternative products.
Troubleshooting
Grease washes out rapidly
Ensure the correct grease type (K99) is used for water-exposed applications. Verify that the bearing seals are intact and functioning properly. Check if the application environment exceeds K99's water resistance capabilities or if the grease was applied incorrectly.
Corrosion observed on bearing surfaces
Confirm that K99 was applied correctly and that there are no gaps in coverage. Check for contamination of the grease during application or storage. Ensure the operating environment is within the intended use parameters for K99.
Premature bearing failure
Verify that K99 was compatible with the previous grease and that old grease was adequately purged. Ensure the correct amount of grease was applied; over- or under-lubrication can cause damage. Confirm that the bearing load and speed are appropriate for K99 lubrication.
Grease appears emulsified or separated
This can indicate prolonged or excessive water ingress. Check bearing seals for damage. If the grease has been exposed to extreme conditions or prolonged submersion, it may need to be replaced more frequently than initially planned.
Pros and Cons
Pros
- Superior water resistance in wet environments.
- Excellent protection against corrosion and rust.
- Maintains lubrication integrity even with water contact.
- Good sealing capabilities to keep contaminants out.
- Suitable for a wide range of bearings in challenging conditions.
Cons
- Requires compatibility check with existing greases.
- Over-lubrication can be detrimental, similar to other greases.
- May not be suitable for extremely high-temperature applications without further specification.
- Primarily designed for water resistance, specialized extreme pressure needs might require different formulations.
Setup, Compatibility & Care
Initial Application:
- Compatibility Check: Before applying K99 for the first time, it is crucial to check its compatibility with any previously used grease. If incompatibility is suspected or confirmed, the old grease should be thoroughly purged from the bearing before applying K99.
- Purging: Remove as much of the old grease as possible. For bearings, initial purging may involve running the equipment briefly after applying K99 to expel residual old grease.
- Quantity: Apply the recommended amount of grease as specified by the bearing manufacturer. Over-lubrication can lead to excessive heat and premature failure.
Compatibility:
K99 is generally compatible with many other greases, but specific chemical compositions can vary. Always err on the side of caution and perform a compatibility test if unsure. It is rated to DIN 51502 K2/3G-20 and ISO 6743-9 L-XBCHB2/7, which may help in cross-referencing.
Care:
- Store K99 in its original container in a cool, dry place, away from direct sunlight.
- Keep containers tightly sealed when not in use to prevent contamination and moisture absorption.
- Regularly inspect lubricated components for signs of wear or contamination, and re-grease according to the manufacturer's maintenance schedule.
