La Grange Grade 10 very high precision superior hardened 440c STAINLESS
steel ball bearings for your precious VINTAGE BICYCLE.
USE OF YOUR ORIGINAL RETAINER OR LOOSE BEARINGS.
A special bundle specifically put together for your precious vintage bike.
grade 10 is a higher precision than the regular 25 grade ball. The lower the number the higher the precision! There is no need to go better then grade 10, this will be overkill and these grades 10 are WITHIN the HRC 55 TO 65
HARDNESS SCALE.
a G10 ball of the same nominal size will have a diameter more closely matching the nominal, with just a ±0.0013 mm maximal deviation. Similar goes for other types of deviations (surface roughness etc.). The lower the grade number, the closer a ball is to a perfect shape.
I too was a serious road bike worrier when these types of hubs were on pro bikes. I know what it feels like to have superior bearings in my hubs, headset and bottom brackets.
I do not recommend using these premium bearings in a Wal-Mart type bike.
TREAT YOUR HUBS WITH THE BEST GRADE 10 STAINLESS STEEL BEARINGS AVAILABLE.
YOU WILL NEED RUBBER GLOVES TO HANDLE THESE BEARINGS. GRADE 10 IS VERY SLIPPERY AND WILL GET AWAY FROM YOU.
PLEASE CHECK SIZE FOR ACCURACY.

W
e did a simple test. In the second too last photo; we let a g25 chrome ball bearing sit in salt water for 24 hours. The stainless steel ball bearing is on the right and the chrome ball is on the left. Which one would you want in your hubs?
If you are not satisfied with our bearings; we will refund your money in full and pay for return shipping. GUARANTEED!
For those who are familiar with ball bearings know that grade 10 are very high precision to where they are very slippery when handling them. These grade 10 bearings are  made from 440c stainless steel for a lifetime of use! Chrome balls will ca-rode in time. Plus grade 10 stainless will spin faster than your regular chrome ball bearings and tolerate heat better at higher RPM. How many times have you opened up a set of hubs and the chrome balls lost the chrome and looked brown and rusty and also found rusty water coming out of your hubs. Not with stainless steel!
The differences between a Grade 25 and 10 bearing for cycling are noticeable and many companies use Grade 10 for this reason.
These additional tolerances provide greater precision and lower rolling resistance. (meaning: these will last longer and run smoother)
PLEASE MEASURE
YOUR OLD BEARINGS FOR PRECISION ACCURACY.
Balls are manufactured to the precision requirements noted in ANSI/ABMA Std. 10A for steel balls and ASTM F2094 for ceramic balls. These standards require that balls meet the limits for ball diameter, spherical form and roughness noted below for each grade level. Lower grade numbers denote more precise balls, which help to improve accuracy, reduce running torque and lengthen lube life. With few exceptions, NHBB manufactures its precision bearings with grade 10A and 10C balls or better. 440c stainless steel balls offer the precise geometry and fine surface finish that makes them especially useful for bicycles and many other applications with the added benefit of
corrosion resistance.
440 stainless steel is a high carbon martensitic stainless steel which has high strength, greater hardness and wear resistance then chrome balls. This type of stainless is capable of attaining, after heat treatment, the highest strength, hardness and wear resistance of all the stainless alloys. Unlike some stainless steel, this 400 series metal has a composition which allows it to be attracted to a magnet.
AISI type 440C stainless steel balls offer the maximum in material strength and superior
corrosion resistance
. They resist alcohol, water, many petroleum products, organic materials and steam. Type 440C balls are used in many applications including bearings, valves, locking mechanisms, fasteners and quick-disconnect couplings and are highly resistant to rolling-contact fatigue.
Balls are manufactured to the precision requirements noted in ANSI/ABMA Std. 10A for stainless steel balls

In the last pic: is a photo of 25g chrome balls i pulled out of old campagnolo hubs. You can see the
arrow
pointing at the chrome
literally
peeling off.  Chrome balls rust.  Not with stainless!
