I ride about 3,000-4,000 miles a year and my rule of thumb is to do the hubs every 300 – 500 miles or so, and the bottom bracket twice a year. Works out to a hub overhaul about every other month. Both of these are more frequent than the suggested schedule.
How often should you grease bike hubs?
Some racers use oil instead of grease, for less friction. If you use oil, you must oil the hubs every week or two, or risk serious damage to them.
How often do wheel bearings need to be replaced?
Your wheel bearings have a heavy impact on the handling of your vehicle. It would be extremely dangerous to drive with old wheel bearings, as it may cause your wheels to stop turning entirely and abruptly. You should expect to replace wheel bearings every 85,000-100,000 miles.
How do I know if my bike bearings are bad?
Worn out or dry bearings will feel rough, metallic and dry. Sometimes they’re so dry that if you pull your finger fast across the axle you can make the axle keep spinning because there’s no grease inside the bearings to slow it down.
How long do bicycle wheel bearings last?
Bike wheel bearings should be changed every 1 to 2 years, depending on their quality and riding habits. Assuming that they’re well-lubricated and properly maintained when needed, most ball bearing with steel races will stay in working condition for at least three to four years.
How long do Sealed bearings last?
Shelf life of sealed bearings
Lubricant deteriorates over time as a result of ageing, condensation, and separation of the oil and thickener. Therefore, sealed bearings should not be stored for more than three years.
How long do bike hubs last?
Guru. If it wears out completely you end up pedalling fast and going nowhere. Mine seem to last about 5,000 to 10,000 miles and the usual signs of wear are noises and play. Price depends on quality, but they’re not bank-breakers.
How do you lubricate bicycle wheel bearings?
They can get “brinneled” or damaged in a crash or something, but 1500 miles is absurd. As for a bottom bracket, on the low end, maybe 5000 miles. The basic Shimano one most people use (UN51/55/similar) can reasonably expect 10k+ miles. But sometimes you get unlucky and get a bottom bracket that lasts maybe 500 miles.
How long do wheel bearings last?
Most wheel bearings last about 85,000 to 100,000 miles before they need to be replaced. Some vehicles have wheel bearings that last a lot longer, and some vehicles need them replaced fairly quickly. It all depends on the quality of your wheel bearings and your usual driving conditions.
How often should a sealed bearing be greased?
Using the chart and the formula, the bearing only needs 8 grams of grease every 10,000 hours. If your grease gun delivers around 1.35 grams per stroke, that means the bearing needs 6 strokes every 13 months; you could average it out to a stroke every 8 weeks or so.
How long does it take a mechanic to change a wheel bearing?
Replacing a single wheel bearing can take 90 to 120 minutes depending on the type of vehicle and complexity. There are a lot of moving parts that need to be maintained and properly sealed to complete this type of work.
What happens if bike bearings fail?

Can you over grease a wheel bearing?
EFFECTS OF OVER GREASING
An abundance of grease in a bearing cavity will cause rotating bearing elements to begin churning and pushing the grease out of the way, resulting in energy loss and increased temperatures.
Why do you need to repack wheel bearings?
Repacking a bearing is the process of removing the parts of the wheel to access, clean and add grease to the bearings. Over time the trailer bearings will take a large amount of abuse and wear, although they are designed to last for a long time, they will wear out prematurely if they are not routinely taken care of.

How do you service a sealed bearing?
Is White Lithium Grease good for bicycle bearings?
Yes, you CAN use that crap as a light lubricant and seize preventant, but it’s way too thin for use as a bearing grease. If you ask 99% of the population what “white lithium grease” is, that’s what they’ll mention.
