MOD 1.25 Steel Spur Gears

Specialist Product Range - Please allow up to 7 working days for dispatch of any item from this product range. Orders placed that also contain normal stock items will be held back and shipped once the Special Order Gears are ready for dispatch.

Gears manufactured to DIN 867, DIN 3962 and DIN 3963. Tooth width 15mm, overall width including boss 25mm.

These gears are supplied with a pilot bore that can be machine 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 gears but also drill and tap for set (grub) screw fixing. See the 'Custom Machining' tab with each product for more information.
