ATV quad, front wheel ball bearings not tappered roller bearings.

In summary, the conversation discusses the failure of three out of four front wheel bearings on a Chinese built ATV quad after only a couple of hours of operation. The individual suggests that the failure may be due to incorrect installation of the wheel bearings or the use of inadequate ball bearings instead of tapered roller bearings. They also mention the possibility that the bearings were of low quality.

My friend bought a budget, Chinese built ATV quad. It has two wheel drive. The front wheels have pairs of ball bearings. After only a couple of hours of operation 3 of the 4 front wheel bearings failed big time. I came up with two guesses as to why the bearings failed so quickly.

1. The wheel bearings have a spacer between the inner races of the inner and outer wheel bearings. If the spacer does not match the spacing of the bearings when they are installed in the hub and axle shaft nut is tightened then the bearing will under go forces they were not intended for?

2. Ball bearings should have never been used and tapered roller bearings should have been used instead?

Any ideas if guess 1 or 2 is likely?

Thanks for any help!

Ball bearings are a very poor choice for heavily loaded applications, but unless the were severely undersized, they should have lasted longer than a couple of hours.

So... I would say both, and 3 = The bearings are probably very poor quality.

It is recommended to check the bearings at least once a year and replace them if there is any sign of wear and tear. If the ATV is used frequently or in harsh conditions, it may need more frequent replacements.

Are ATV quad front wheel ball bearings better than tappered roller bearings?

Both types of bearings have their own advantages and disadvantages. ATV quad front wheel ball bearings are typically more affordable and easier to replace, while tappered roller bearings are more durable and can handle higher loads. It ultimately depends on the specific needs and usage of the ATV.
