Helicoid Lube+ Damper Grease for Lenses & Cameras

Helicoid Lube+ is a premium-grade synthetic optical lube that comes in 6 different thicknesses, from NLGI 000 to NLGI 3, covering most of the typical lubricant scenarios on camera lenses.

The focus rings on vintage lenses are often less smooth (or sometimes over-loosened) than they used to be. This phenomenon is because the damper grease has deteriorated and dried up over time. Time to replace the grease!

• 100% synthetic grease with PTFE additives.
• Translucent and odourless lube with a consistent flow.
• Resistant to a humid environment.
• Wide operating temperature range.
• Made in the UK, Superior Quality.

Polar Bear's Note (for reference only):

Choosing the right grease for helicoids can be complex, so we'll do our best to cover some important considerations.

1. Picking the right grease:

There are numerous types and models of dampening greases used on camera lenses, and there is no single grease suitable for all applications. The design and manufacturing tolerance of the helicoid heavily influence the choice of grease.

For example, helicoids with smaller pitches typically require less friction to operate and therefore may benefit from using a softer dampening grease. Additionally, the length of the helicoid usually influences the contact surfaces and the required level of dampening. Furthermore, the weight of the optical group plays a significant role. The dampening power must be sufficient to support the group when pointing upward and downward. This is particularly crucial in the helicoid mechanism of zoom lenses.

Finally, manufacturing tolerance is critical. For example, Soviet lenses are noted for their mixed construction, which often includes large gaps in the helicoid assembly. As a result, a harder dampening grease is commonly advised. In contrast, the helicoid in Nikon lenses is noted for its extremely high-tolerance manufacturing, requiring less and softer grease.

2. Apply it right:

When replacing the dampening grease, the deteriorated grease must be removed completely. Washing the part with degreaser is highly recommended. Lighter fluid and isopropyl alcohol are commonly used for degreasing helicoids.

After the parts are cleaned thoroughly, assemble the helicoid and perform a dry run. This test will show if any thread correction is needed, or if there are dents or bends. Furthermore, it will let you know how much dampening is required.

When putting on new grease, the golden rule is 'less is better'. Never overdo it. If it is too loose, replace the grease with a firmer one. Replace the grease with a softer one if it is too firm. Only a very thin grease coating is needed, except for the helicoid, which has large gaps between its parts. Adding too much grease will lead to oil leaks and contaminate other parts of the lens.
