Frequently Asked Questions
Q: What types of loads can these tapered roller bearings handle?
A: These tapered roller bearings are designed to handle both radial (perpendicular to the shaft) and axial (along the shaft) loads simultaneously, making them ideal for gearboxes, wheel hubs, differentials, conveyor systems, and other demanding mechanical applications.
Q: How do I choose the correct bearing model for my application?
A: Select based on your shaft's bore diameter. For example, model 32904 fits a 20mm bore shaft, while 32905 fits a 25mm bore shaft. Always cross-reference the outer diameter and width with your housing specifications before ordering. Refer to the product images for full dimensional diagrams.
Q: Are these bearings compatible with standard housings?
A: Yes. All models in the 329 series conform to standard international bearing dimensions, ensuring compatibility with most commercially available housings and mating components that accept the corresponding size series.
Q: What material are these bearings made from?
A: These bearings are manufactured from premium bearing steel, which offers high hardness, excellent wear resistance, and reliable performance under continuous operational stress — suitable for both light and heavy-duty machinery.
