QUALITY COUNTS…….5 YEAR WARRANTY INCLUDED
All of our bearing sets can meet ABEC 5* grade ratings for ball bearings and are made by Nachi. (We highly doubt the cheap sets online are even rated) Our bearings are high speed electric motor grade bearings. The same quality bearings we have been using in our own business for the past 6 years without any issues. That is why we have stayed with them. We have installed over 500 of these bearing and seal sets in our repair business.
Our bearings and seals are the best grade we can buy at a price that we can remain competitive and more than sufficient for the purpose we are using them for. The fastest washer out there spins at 1500 RPM and our bearings and seals are rated for more than 6 times that speed and load. The smallest bearings we use are rated for 1740 LBS and the bigger bearings go up to over 4700 LBS. That's more weight than a Minivan.
As for our seals, We buy them from Taiwan, Germany, and Japan depending on the size and availability. (USA made seals are not available in these sizes) All our seals are high quality, fully sprung, double lip seals and are the same ones we have been using for 6 years on our own machines.
Just to let you know, we are regularly approached by the same manufacturers as the cheap guys. They quote us between 0.65 cents and $1.10 per bearing. We don't know about you but we're not putting dollar bearings in any of our washers.
And please don't forget...... We give a 5 YEAR WARRANTY and UNLIMITED TECH SUPPORT.
Things to know about ABEC ratings:
1) Bearings not conforming to at least ABEC 1 cannot be classified as precision bearings as their tolerances are too loose.
2)Lower ABEC grades are intended for applications such as mechanical hobbies, skates, skateboards, fishing reels, and alike.
3)Mid-range grades (ABEC 5) are intended for applications such as vehicles, electric motors and industrial machinery.The maximum allowable tolerance on these bearings is 0.0035 mm. These are the ones we sell.
4) High grade bearings are intended for precision applications like aircraft instruments, jet engines, or surgical equipment. These can often cost many hundreds of dollars each. As a side note, the supplier we use has also sold to NASA. The highest precision bearing they have sold to date was for the international space station and cost $128,000. It was 8 feet in diameter and was an ABEC grade 9.
We hope this helps. Please let us know if you have any questions.
*(ABEC)-Annular Bearing Engineering Committee. The ABEC scale is the industry accepted standard for the tolerances of ball bearings.
