Low-Temperature Damping Grease is specially designed for precision mechanisms operating under high and low temperature conditions (-20℃ to 80℃). Its core advantage lies in maintaining stable torque across a wide temperature range, ensuring effective damping and shock absorption for precision positioning mechanisms, fine-tuning devices, and stiction/ buffering components. This allows moving parts to operate smoothly, gently, and accurately.

Typical Applications Include:

• Damping and anti-slip mechanisms for lens focusing in cameras, microscopes, telescopes, and rangefinders

• Turntable damping gears and switch devices in disc players

• Other precision mechanical components requiring stable damping performance at low temperatures

• 
  

To ensure optimal performance and safe use, please strictly follow these precautions:

• Clean and Dry: Before application, ensure that the area to be greased is completely dry, clean, and free of contamination.

• Prevent Contamination: During use and storage, strictly prevent dust and foreign particles from mixing in. Always tightly seal the container after use.

• No Mixing: Do not mix with other types of greases, as this may cause adverse reactions, reduce performance, or damage components.

• Plastic Compatibility: For special plastic parts, conduct a compatibility test or obtain explicit approval from the plastic manufacturer before use to avoid swelling, embrittlement, or other adverse effects.

• Proper Storage: Store the product in a clean, dry, cool, and dark place.

1. Anti-Wear Performance Test (SH/T 0204)

Using a specialized anti-wear testing device, under a specified load, the upper steel ball rotates relative to three stationary steel balls on the lower surface, which are coated with the grease sample. After the test, the wear scar diameters on the three lower steel balls are measured. The size of the wear scars is used to evaluate the anti-wear performance of the grease.

2. Four-Ball Test Method (GB/T 3142)

In the four-ball test, grease is applied to a ball cup, and under a specified load, the upper bearing steel ball rotates at a set speed against three stationary steel balls below. After a period of operation, the wear scar diameters are measured to evaluate the extreme pressure (EP) performance of the grease.

There are three common expressions for this method: PB value, PD value, and ZMZ value:

• PB value: The maximum load under which no seizure occurs during the test, expressed in Newtons (N).

• PD value: The minimum load at which the rotating ball and the three fixed balls weld under the test conditions, expressed in N.

• ZMZ value: An indicator of the grease’s resistance to extreme pressure under applied loads. During the test, the load is incrementally applied to the three stationary balls in 0.1 logarithmic units, and the first ten seizure load results are used to calculate the ZMZ value, expressed in N.

3. Timken Test

This test is performed using a Timken test machine. Grease is applied between the friction surfaces of a metal ring and steel block under a specified load and speed. After a period of operation, the wear marks on the metal balls are examined to determine the EP performance of the grease, represented by the OK value.

• Purpose: To analyze the grease’s ability to resist loads under line contact.

• Test Method: SH/T 0203

4. Four-Ball Extreme Pressure Test (GB/T 12583)

This method is also expressed using three indicators: PB value, PD value, and LWI value.

• LWI value: Indicates the extreme pressure capacity of a sealed grease under a limiting load. It is determined by applying incremental loads in 0.1 logarithmic units on the three stationary balls and performing ten tests before the seizure point. The average corrected load represents the LWI value.

Extreme Pressure (EP) Grease

As the name suggests, extreme pressure (EP) grease is specially formulated to withstand high-pressure conditions. It is particularly suitable for heavy-load, high-impact, or high-vibration working environments, such as heavy machinery, mining equipment, or high-speed industrial machinery. In such harsh conditions, ordinary greases often struggle to maintain effective lubrication, leading to mechanical failures. EP greases, enhanced with special additives, can provide long-lasting lubrication even under extreme conditions.

Key Features of EP Grease

The excellent durability of EP grease is mainly due to its composition. It typically contains special extreme pressure additives, which form a protective film under high pressure to prevent direct metal-to-metal contact, significantly reducing wear and damage. Additionally, the base oils and thickeners in the grease also contribute to its extreme pressure performance.

However, not every lubrication scenario requires EP grease. The choice should be based on the actual working conditions of the equipment and the manufacturer’s recommendations. Overuse or improper use of EP grease may be counterproductive and negatively affect equipment performance.

Specialized Industrial Grease

In summary, industrial greases marked as EP represent high-performance, extreme-pressure-resistant lubricants. They ensure efficient lubrication in heavy-load and harsh environments, extend equipment service life, and help maintain reliable production operations.

A planetary gearbox is a mechanism designed to reduce motor speed while increasing torque. Its internal planetary gears are the core components of the gearbox, and special attention must be paid to lubrication when operating under extreme high or low temperatures. A high-quality, fully synthetic grease should possess the following four key functions to meet the lubrication requirements of planetary gears.

1. Lubrication and Wear Protection

During high-speed operation, the teeth of planetary gears engage and rub against each other rapidly, which can accelerate gear wear. Using grease forms a lubricating elastic film on the gear surfaces, reducing direct metal-to-metal contact and friction, thereby minimizing gear tooth wear.

2. Enhance the Durability of Planetary Gear Contact Surfaces

The contact stress on gear teeth is a primary factor leading to reduced gear strength. The lubricating film formed by grease helps distribute the stress across the gear surface, thereby improving the durability of the gears.

3. Prevent Adhesive Gear Surface Damage

Adhesion is a common failure mode in gear transmissions. Specifically, when the load and speed on the gear mesh exceed the limit that the lubricating film can withstand, the film may rupture, causing direct friction between the contacting gear surfaces and resulting in wear. As friction intensifies, the temperature of the gear surfaces rises rapidly, which may lead to adhesion and gear surface damage. Grease, with its anti-adhesion properties, load-bearing capacity, and extreme pressure (EP) characteristics, ensures effective separation between gear teeth, effectively preventing adhesive damage.

4. Reduce Transmission Noise and Vibration

Gear vibration and noise can arise from multiple factors, making the choice of grease particularly important. A suitable gear grease, due to its viscosity, can significantly reduce gear vibration, impact, and noise. However, the effect on vibration and noise may vary depending on the lubrication method and the specific type of grease used.
