Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
Yes this is normal. When they are under load, they will not make that noise. We have driven robots around with these wheels on and they are not noisy at all.
Let us know after you get them integrated on a robot how they sound / perform. Paul |

Just a short comment that 1676 is very pleased with the 2 stage ball shifters we received last week. They assemble quickly, shift like a dream, and our break in process did not reveal much metal dust in the grease.
Can't wait to get 150 hours on them! |

Do y'all have any idea when the 1/2" hex bearings will be back in stock? They're an important part of making all of the rest of your stuff work right. :)

For what it's worth, we also experienced significant (visible) wobbling on 2 of the 4 1/2 inch hex bearings we ordered. I don't have a video of it, but I just wanted to bring it to your attention that it's probably not just an isolated case.

Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
FWIW, of the 80 I just got, 20+ are so far exactly what we expected. There's a little variation on how well they fit on VEXPro .5" hex stock, but none of the 20 were out of center.

Ricky, Paul,
Any idea on when the Hex bore versa-hubs will re-stock? |
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products

We are currently inspecting them. We will be putting some back in inventory late today, but a limited quantity. Basically, the supplier broached the hex such that some parts are seeing a .006" to .010" runout to the flat face and to the versakey pilot. We are putting the good parts in inventory and reworking the parts out of specification. If you are in a pinch now and have access to a hex broach, you can broach the 1/2" round with keyway to a 1/2" hex. Paul |
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
The 1/2" hex bore VersaHubs are now back In Stock in limited quantities.
The website will be adjusted as necessary based on inventory. Ricky |
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
Any idea when we can expect the 1/2" flanged hex bearings?

Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
Is there a .step available for the SMC Valves?
|
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
We have a set of hex bearings that are off center. Who should we contact and when can we expect replacements?
|
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
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.
|
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
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. Paul |
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
Thanks, Paul. I sent in a request for replacements.

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

Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
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? |

Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
We are back in stock of Flanged Bearing - 1/2" Hex ID x 1.125" OD (217-2734), although in a limited quantity.
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). Best, Ricky |
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
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. |

Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
Until RC gets them going, Martin is the go to place for these pinions.

Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
Well, those are some cute little mecanum wheels. Maybe it's VexPro previews time.
|
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
Are those machined from metal stock now?
|
Re: VEX Robotics Relaunches VEXpro Product Line with over 120 New & Improved Products
Oh, as an aside, there was some question last year about how durable the VexPro mecanum wheels would turn out to be. At this point I can state that we used them aggressively all season and they've held up fantastically well.

The VersaHubs for mounting a gear/sprocket to a wheel were plastic, but all the live axle hubs are metal. There is something hidden in Aren's picture too. It's killing me that no one has noticed it yet. |

That's an awesome tiny mecanum wheel, seems perfect for compact octacanum modules.

The hex bearings have been in stock since last month. We have been shipping over 1,000 bearings per week.
