NAMI Motor Seal Set (suit Burn-e, Blast, Klima & Stellar)

• Motor seal set suit all the motors of NAMI Electric models including Burn-e, Blast, Klima and Stellar.
• Supplied as a set (pair, one for each side of a motor - each side is different size). Order Qty 2 for two sets (both wheels).
• Has factory applied white grease.
• Typically required as a renewal in major servicing of motor, such as interior rust inspection or bearing change. Renewing seal periodically is good practice to prevent rust forming inside the motor over long term use.

Notes:

1. Bearing disassemble and assemble video by Michael Sha.
   
2. Bearing renewal by ASG After Hours.
3. Seal have a lip which forms the seal. These factory seals are single lip and type OA-17x25x5 and OA-20x28x5 for Burn-e 2 Max (1500w) as mentioned in description of video above and confirmed in field by Yann Lesueur. The designation often has an -NBR suffix. Additionally Kader Amrouche advises the 20x28x5 seal is offered in OAS (double seal) variant OA-20X28X5-NBR. OA = single lip, OAS = double lip. Difference between single vs double are explained by One Monroe suggesting there is minimal improvement to seal and increases friction unnecessarily.
4. These seals differ in thickness to those on Kaabo Wolf GT series (including King GT). GT's require a 1mm thinner 17x25x4 and 1mm thicker 20x28x6. GT bearings are understood to be 6004 and 6203 (specifically RS/RSH, both designations imply seal both sides) as referenced and further validated informing of seals of those seals being 17x25x4(WA) and 20x28x6(WAS).
5. Seal mounts so that the spring sits on the inner side of the wheel, allowing the lip of the seal to be positioned effectively.
6. Try keep your motor seal clean (wash with brush using car wash or dishwashing liquid) to prologue the service life of the seal.
