How long do bike wheel bearings last?
How long does a wheel bearing last? Wheel bearings have an average lifespan of 136,000 to 160,000 km (approximately 85,000 to 100,000 miles). This is only a rule of thumb though, the actual lifespan of a wheel bearing depends on the quality of the wheel bearing and the operating conditions.
What kind of bearings are in bike hubs?
Wheel bearings also wear out over time which will introduce play to the hub, allowing the wheel to rock side to side on its axle. There are two types of bearings commonly seen in hubs, sealed (cartridge) bearings and non-sealed (cup and cone or loose) bearings.
When to replace wheel bearings on a bicycle?
It’s usually best to replace the bearings rather than to reuse the old ones (new ball bearings aren’t expensive). You should also replace any worn axle parts at this time. On rear wheels, it almost always best to remove the cluster of gears (called the “cassette” or “freewheel”) before attempting to service the hub bearings.
Why do my wheel bearings feel smooth when I turn them?
Hold onto and turn the axle because it’s holding the parts in contact with the bearings. Hub bearings in good condition will feel smooth when you turn the axle because the grease inside is coating the bearings preventing metal-on-metal contact.
Do you have to grease your bike wheel bearings?
They must be properly adjusted and greased. To find out if they need greasing without taking everything apart, simply remove the wheel from the bike, support the axle horizontally with your fingers, and turn the wheel slowly –try not to tilt the axle as it rotates.
