FAQ

Tapered roller bearings require a specific preload for optimal performance. It is crucial to follow the manufacturer's guidelines, using proper tools to press the cone and cup into their respective housings and shafts. Incorrect preload can lead to premature failure.

The appropriate lubrication depends on the operating speed, temperature, and load. Generally, a high-quality grease with an EP (Extreme Pressure) additive is suitable for most applications. For high-speed or high-temperature environments, oil lubrication might be necessary.

Yes, the 31309 designation is an ISO standard. This means it is dimensionally interchangeable with bearings of the same number from other major manufacturers like SKF, FAG, or NSK. However, internal geometry and material quality can vary, potentially affecting performance and lifespan.
