Next Shipping Day 3rd December

We are now in the process of moving Technobots 120 miles North to the Town of Rugby. You can still place orders on-line as normal but they will not be dispatched until after we re-open on the 3rd December

Machining Services

Our machine shop is also being re-located so we are unable to carry out machining modifications on gears, sprockets, pulleys etc. Any order placed which includes machining options is unlikely to be processed until mid December.


0.375 Inch Steel Chain Sprockets

High quality 3/8" pitch British Standard sprockets in the most popular sizes. Sizes we do not stock at technobots are available through our gearsandsprockets website that offers a far greater range of transmission components.

These sprockets are supplied with a pilot bore that can be machined to a larger accurate diameter (subject to boss size) although many users find the pilot bore quite acceptable. Using our 'Custom Machining' service, we can not only bore out these sprockets but also drill and tap for set (grub) screw fixing. See the 'Custom Machining' tab with each product for more information.
