VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products

[Akash Rastogi]

We have a set of hex bearings that are off center. Who should we contact and when can we expect replacements?

[Shu]

We are finding that nearly all of our hex bearings are off center. I think this is becoming a major issue among teams not knowing when good parts are going to be available.

[Paul Copioli]

It is always a good idea to contact customer service at support@vexrobotics.com or 903-453-0802.

While John, Ricky and I check CD, our customer service department responds to customers who call and email. Every customer who contacts our support line directly is having their bad bearings replaced.

The issue that went undetected was that the hex was broached off center. Our standard bearing race runout test did not detect this failure mode. We have now set up a special hex runout test on every hex bearing.

The reason the bearings are out of stock is so we can replace all the bad bearings that have already been received by customers.

For extra information, only the 1/2" hex bearing is affected. The 3/8" hex bearing is not affected by the defect.

Thanks, Paul. I sent in a request for replacements.

We just got our robot driving today and encountered an interesting noise. After some basic testing we believe to have narrowed the noise down to our brand new victor 888s. When they are given a a signal other than stop they emit a buzzing noise. They appear to work correctly, driving our cims under a fair amount of load for about 5 minutes or so.

We were just wondering if this noise is intentional or not. What can we do about it, and is there a way to stop it?

-Thanks

The Victor 888 operates at 1,000 Hz which is in the audible range for us humans. The noise is normal and expected.

This may want to be noted somewhere official. We certainly found the noise a tad bit concerning when we first heard it.

There probably isn't anything we can do about the volume of it then?

I'm getting "This mailbox is full". Hopefully I get a response to my email about buying master links individually, or a supplier that carries a compatible one.

Due to the limited supply, we are only taking orders for these via credit card over the phone at 903-453-0802. Limit of 10 per order.

Also, we are also back in stock on the 1/8" Delrin Washer (10-pack) (217-2758).

Any plans on stocking an 11 tooth CIM gear, like West Coast Products?

It offers the nice ability to tweak the gear ratios in the gearboxes, without a massive change, and it's a product I'd really like to see.

I don't know that I have ever seen the WCP 11 tooth gear in stock. Besides, I doubt VEXpro can compete with WCP's price of $0.00.

On a more serious note, I second this motion. It offers a lot amount of design flexibility.
