The 608RS uses rubber contact seals, offering better contamination resistance at the cost of slightly higher drag. For most skateboard and general-purpose use, either works well — the RS is the better choice in dirty or wet conditions, while the Z excels in clean, higher-speed applications.\u003c\/div\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003cdiv class=\"faq-q\"\u003eWhat does ABEC-7 mean?\u003c\/div\u003e\n    \u003cdiv class=\"faq-a\"\u003eABEC is a precision rating scale for bearings — the higher the number, the tighter the manufacturing tolerances. ABEC-7 is a high-precision rating, meaning tighter dimensional tolerances and smoother, more consistent running compared to lower-rated bearings like ABEC-1 or ABEC-3. This makes it well suited to applications where smooth rotation and low runout matter.\u003c\/div\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"faq-item\"\u003e\n    \u003cdiv class=\"faq-q\"\u003eCan I clean and re-grease this bearing?\u003c\/div\u003e\n    \u003cdiv class=\"faq-a\"\u003eYes — the metal shields can be carefully removed with a thin pick or blade. Flush out the old grease with a solvent, allow it to dry fully, then repack with your preferred bearing grease before replacing the shields.\u003c\/div\u003e\n  \u003c\/div\u003e\n  \u003chr class=\"divider\"\u003e\n  \u003cp class=\"note\"\u003e\u003cstrong\u003ePlease note:\u003c\/strong\u003e Carbon steel construction is not suitable for wet or highly corrosive environments — consider a stainless steel variant for those applications.
