Yakamoz 10Pcs Router Bits Top Mounted Ball Bearings Guide for Router Bit Bearing Repairing Replacement Accessory Kit | Inner Dia. 3/16” & Overall Dia. 1/2”

Fit fine on my router bits. Will need to see how they hold up in use. FYI, the height of the larger diameter bearings Yakamoz offers is 5mm and the height of the smaller diameter bearing is 4mm. Together, these two sets can replace the the vast majority of the bearings on my router bit sets. I blew out a bearing on the the first use of one of my admittedly cheap router bits, but that may have been due to lack of lubrication. I recommend all bearings be lubricated prior to first use and keep clean and oiled thereafter. There is a lubricant made specifically for this use, though it seems air tool oil and the venerable Marvel Mystery Oil can be used as well.

To the tolerance I can measure with a dial caliper the bearings match the Whiteside B3 in outside, inside diameter and height. They appear to be good replacements. The screws are a different thread to Whiteside so of no use for my router bits. The Whiteside screws have thread 5-40 while these screws appear to be m3-.5. I suspect the screws will work in imported router bits.

Bought low priced router set from big box store. The bearings blew out three times before the job was finished. Ordered these and they came just in time for the next blow out. After installation these bearings actually felt smoother with palm router and have not failed yet. Turn your low price router bits in to reliable bits.

Good product but we will see how long they last.

dont hold up

Works fine. Just wish they would add that special washer under the bearing. Would pay a little more for the set since this was to replace a damaged bearing.

Great buy. This are much cheaper than getting one from a tool store and so far they work great. I replaced the old bearings on two router bits, both work fine. Used them both when building a cabinet. I also replaced the frozen bearing on my outside wind direction indicator. Go figure, right size.

I like to replace some of the bearings on the router bit if the job would be time consuming if my bearing gives out and wrecks my work. These bearings seem to do the job quite well. Was quick to receive my order.

Im definately happy with this product, and its great that they come with screws.

Hood fitting bearings and new bolts with them. So nice to have in the shop for when one gets loose or hot.
