Greases are typically classified based on their temperature range and performance characteristics. The consistency and smoothness of a grease can be significantly affected by the operating temperature. Choosing the right grease for a specific application ensures that bearings operate efficiently and last longer.
In terms of oil classification, oils can generally be categorized into low-temperature (LT), medium-temperature (MT), and high-temperature (HT) types. Additionally, there are specialized oils such as EP (extreme pressure) and EM (molybdenum disulfide enhanced), which provide improved film strength and wear resistance under heavy loads or extreme conditions.
Selecting the correct lubricant is crucial. Using an incorrect type of grease can render all other bearing protection measures ineffective. It’s essential to choose a grease that performs optimally at the given operating temperature and environmental conditions. While manufacturers often recommend specific greases, many bicycle bearings do not come with detailed lubrication instructions. Therefore, it's important to ensure the bearing operates in the best possible condition.
When choosing grease for your bicycle, it's wise to go for a product with medium viscosity, high water resistance, and good extreme pressure properties. Many options are available in the market, and one popular choice is Thailand 202 (also known as Star 2). This grease meets most common needs and is usually priced around 25 yuan per kilogram. However, its high viscosity can make it slightly difficult to rotate by hand, and it may even stick to rubber seals in some cases. It works well with hubs like Shimano and road bike axles, especially for high-pressure, low-speed bearings.
Another excellent option is SKF LGEP-2 lithium-based grease. It offers similar benefits to Thailand 202 but has lower viscosity, making it smoother for shafts and heads that require frequent transitions. Although it is more expensive, its reliability and long-term performance make it a worthwhile investment.
You can find this high-quality grease at SKF resale shops near you. While the price is higher, the improved performance and protection for your bearings make it a valuable choice.
