# Reading the 36 × 68 × 33 mm Envelope on DAC36680033
The envelope to write on the ticket is 36 × 68 × 33 mm. That geometry belongs to DAC36680033, a wheel hub bearing with multi-lip seal. Measure the removed part or the housing before you trust a faded stamp.

Typical duty includes automotive hubs that specify this sealed cartridge. Material on this listing is bearing steel. If your equipment sits outside that range, say so on the request rather than forcing a familiar part number.
Do not substitute a 36 mm-bore hub with a different width or a neighboring DAC36xxxx unit. The multi-lip seal is part of the duty. Confirm 36×68×33 mm on the knuckle and do not pry the seals on a new unit.
