Should I use ABEC-3 C3 or ABEC-5 CN for my suspension pivot?

Check your frame manufacturer's bearing service guide first. If unspecified, ABEC-5 CN provides better precision; use C3 if the pivot has known misalignment or runs hot.

What is the LLU vs LLB difference?

LLB = rubber contact seal both sides. LLU = rubber lip seal both sides (non-contact on one side). The LLU/LLB designation on this bearing indicates full contact sealing on both faces for maximum contamination protection.

Can I install these without a bearing press?

No — always use a proper bearing press or correctly-sized installation tools. Using a hammer directly risks damaging the race geometry and pre-loading the bearing.
