The AROMA series of grinders, the grinders have a unique Lid opening system. They have been designed to open in two simple steps.

The Lid

See video

Lift the lid of the grinder directly upwards and off. Twisting, clamshell technique or rocking will hinder the function.

Bottom plate (AROMA-3 only)

See video

Like a clamshell, pivot open the bottom plate or remove by lifting upwards.

Generally a bath in hot soapy water will remove any residue built up over time.

Avoid any harsh chemicals as this could ruin the Stainless Steel finish.

Please remove the bearing before any liquid is applied to the lid. (We have a bearing install/removal tool to help with this)

We’ve tested many different bearings over time, and not all are created equal. After extensive research, we've chosen SKF’s 608-2RSL bearings for our products because they offer the quality and precision we require. These bearings provide superior seals and consistent sizing tolerances, ensuring a smoother, more reliable fit. Their polished surface allows our grinder lids to slide smoothly on and off the center post, unlike traditional skateboard bearings.

One downside, however, is that the SKF bearing has a shorter spin time, averaging around 10 seconds, compared to typical skateboard bearings. For those interested in experimenting, we offer a tool that allows customers to try different bearings. Please keep in mind that our support and warranty apply exclusively to the SKF 608-2RSL bearing; if any issues arise, we’ll be able to assist only if this specific bearing is in use.

Please refer to the FAQ entry "Why did you choose SKF 608-2RSL bearings for your grinders?"
