1.2.3 For the bearing with a bore diameter of 20-480 mm, the inside diameter is 5 times the last two digits. For example:

1.2.4 For bearings with a bore diameter ≥ 500 mm, the bore diameter is generally given in millimetres. The size identification is separated from the rest of the bearing designation by an oblique stroke, e.g. 511/530 (d = 530 mm).

Phil Wood Waterproof Grease is ideal for bike applications that require superior water resistance and long-lasting protection.

Additives are incorporated into grease formulations to enhance specific properties and provide additional benefits. Some common additives found in grease include: Anti-wear Agents, Antioxidants, Corrosion Inhibitors, Water Resistance Additives.

However, if you frequently ride in wet or dusty conditions, it may be necessary to re-grease more frequently to ensure optimal performance and protection.

Without adequate lubrication, bearings can wear out rapidly, resulting in increased friction, decreased efficiency, and potential damage to components. By using the appropriate lubricant on bicycle bearings, cyclists can significantly decrease the resistance caused by friction, allowing for smooth and effortless component rotation.

By considering these factors, you can choose a bike grease that aligns with your specific needs and ensures optimal performance and protection for your bike bearings.

The temperature range indicates the minimum and maximum temperatures at which a grease can perform optimally. Greases have specific temperature limits, and operating outside these limits can result in inadequate lubrication, reduced performance, or even grease failure. It is crucial to select a grease that can withstand the anticipated temperature extremes of the application.
