4E0010.01-090

Product Description:

The 4E0010.01-090 is a gear and worm set built into the 4E0 PanelWare Accessories series from B & R Automation. The gear’s made of brass, and the worm is cut from steel, so the materials balance low friction with strength. The pitch diameter is 90 mm on the gear, and the module is 1.0 — standard for mid-range torque transmission. It’s a clean fit setup, meant for applications where small gearboxes handle directional shifts or slow rotations.

This unit runs with a 20° pressure angle and a single start on the worm, which makes for smoother engagement under load. The face width is 10 mm, so the contact surface gives enough grip without adding drag. The DIN 3974 module tolerance standard keeps gear teeth aligned right out of the box, with no reshaping needed. The bore diameter is 12 mm on the gear and 10 mm on the worm, so the fit is close and doesn’t allow much play. The center spacing is 45.5 mm, and it’s tight enough to avoid backlash while still allowing motion.

It’s not overbuilt or heavy — just enough precision where it counts. When paired together, the gear and worm stay meshed without noise or shake. Small assembly tools, operator panels, light-duty conveyors are good places to slot this unit in. It is not meant for high-speed runs or heavy output, but excellent when fine control and mechanical stability are more important than brute strength. Teeth wear evenly because of the matched materials, and the brass resists corrosion over time. The 4E0010.01-090 works quietly, fits clean, and stays in alignment if installed right. For compact setups that still demand solid mechanical parts, this one just does the job and keeps on turning.
