Can I use a higher ABEC grade like ABEC-5 here?

Yes — ABEC-5 offers tighter tolerances and marginally smoother rotation. Enduro makes ABEC-5 versions of many sizes (see MR 17287 LLU/LLB CN ABEC-5 variant). For most riders, ABEC-3 provides excellent performance at lower cost.

What does MR prefix mean in the bearing number?

MR denotes a miniature radial bearing with metric dimensions. The following digits encode the dimensions in Enduro's numbering scheme (17287 = 17mm bore, 28mm OD, 7mm wide).

Do I need special tools to install this bearing?

Yes — bearing presses or correctly-sized drift tools are required to avoid damaging the races during installation. Driving on the wrong race can pre-load or damage the bearing immediately.
