What is the maximum speed for timing pulleys/belts (r.p.m or meters per sec) Thanks |

Hi, Our supplier does not specify a figure so we would not recommend a speed of greater than 80m/s for our range of timing belts and pulleys. |

Can you source double sided timing belts (5mm pitch)? |

Ewan, Not currently but we are looking to extend our range of timing belts and pulleys in the future including double sided belts to allow a third pulley to be used i.e. as a belt tensioner. |

Can you tell me if how one of your aluminium timed pulleys might fit onto a shaft, does it have its own method of axial location? Also i saw that there was no pitch specified for the belts or the pulleys, how can i tell if they match? |

Robin, The timing pulleys fit onto a shaft using the supplied grub screw and hex key. The shaft hole is pre drilled but can be enlarge within limits as required. We only supply one pitch of timing belts and pulleys but a good question, they are T5 pitch. We will update the site to reflect this. |

Have attempted to use Aluminium timing pulleys and toothed timing belts to drive the x and y axes of my Chester mill (stepper motor drive, cnc control). Initially the pulleys were separated just enough to put a slight tension on the belt, but in use the belt rose up on the pulleys and jumped one or two teeth per rev. I increased the belt tension with a brass wheel in contact with the outer belt surface on a hinged sprung mount to give adjustable belt tension, and increased the tension until the belt no longer jumped, and this appeared at first to solve the problem completely, however after a few days use, the belts have stretched resulting in tooth jumping all the time. I have thought about a possible remedy and wondered if instead of increasing the tension I place an idler wheel in contact with the back of the belt at the point at which it makes contact with the pulley, so as to physically prevent the belt from rising and so stop tooth skipping. Do you think this would work or do you know any alternative remedy? |

Hi, Belts rising up over the pulley flange is where they are not correctly tensioned. Stepper motors are really harsh on belts, the pulsing nature of stepper motors with the fast acceleration / deceleration can put stresses on the belt than exceeds its performance rating. You could try slowing up the ramp times but it is quite possible that you need stronger belts. Unfortunately we do not supply any other versions of pulleys and belts although we are looking to source them in the future. The ones we supply are T5, AT5 are stronger or you could use wider belts or thicker belts. |

can I glue timing belts to make them longer and (even if you do not advise) what glue shall I use. What are they made of? |
||
| Admin (Admin) Board Administrator Username: Admin Post Number: 746 Registered: 10-2004 |
As you did not leave an Email address, we cannot reply personally to you. Our timing belts cannot be cut and glued as they contain a number of steel wire strands for strength. |

I want to get a 6:1 ratio with 10mm timing pulleys without having to make a compound. I see that you do not specify a 60 teeth pulley in your stock list. Have you any thoughts about where I could get such a pulley? |

Alan, Our supplier does not produce anything larger than this so sorry we are unable to help. |

I need a toothed belt, 5mm pitch, but only 15cm in circumference. Is it possible to cut and rejoin a larger belt? |
||
| Admin (Admin) Board Administrator Username: Admin Post Number: 937 Registered: 10-2004 |
Martyn, The smallest belt we stock is 165mm in circumference. Our timing belts cannot be cut and glued as they contain a number of steel wire strands for strength. |

Hello, I recently ordered some timing pulleys, they were on the order number MA76AE20013798. Your website specified that the parts 4620-110, 4620-120, would not be bored through, however when they arrived we discovered that they had been bored. Therefore they are not ideal for the purpose we require them for. This has caused an inconvenience because we would have to fabricate sleeves to rectify this problem. Regards, Mike Watts and Colleagues |

Mike, Apologies for that. It appears that despite the manufacturer quoting exact dimensions, they now advise that dimensions are subject to change. We have resolved this with the manufacturer to prevent this from happening again. We will quite happily replace your pulleys if you can return them and we will of course refund the 1st class letter post cost as well. |

Are MFA timing pulleys compatible with synchroflex timing belts and vice versa? Is the toothform identical between MFA and synchroflex products? Is it so that the synchroflex belts are less likely to stretch compared to MFA belts because of the steel wiring? |
||
| Admin (Admin) Board Administrator Username: Admin Post Number: 1138 Registered: 10-2004 |
Hi, MFA timing belts and pulleys are T5 profile so any of the T5 Synchroflex range can also be used with MFA products. Both MFA and Synchroflex belts incorporate steel wires for tensile strength. |

what is the diameter of the boss on the 44teeth MFA T5x10mm? what is the price for the 48 teeth Timing Pulley Synchroflex T5x10mm? Do you have in stock? If no how much will it take? thanks Paul Scicluna |

| Admin (Admin) Board Administrator Username: Admin Post Number: 1150 Registered: 10-2004 |
Paul, We tried to answer your Email but it kept bouncing back. Here is our reply: The 44T pulley has a boss of approx 15mm The price of a T5 x 10mm x 48T are £9.12 each excl VAT and carriage. Please also note that this size does not come with flanges. |

Hi, Are your Synchroflex T5x10mm x 32 and 36 tooth timing pulleys available in Execution 2? thanks. Also price for each of these. Thanks, John. |

| Admin (Admin) Board Administrator Username: Admin Post Number: 1153 Registered: 10-2004 |
Execution 2 is only available for sizes above 42T. We may be able to get specials made for you but there would be a minimum order quantity that may not be of use to you if you only need a few. |
