R&P Knowledge Hub
#99 spindles typically use a 2.375" inner diameter seal surface. Seal outer diameter must match the hub bore precisely—3.623" in this configuration.
Single lip seals are standard for many trailer applications, but double lip versions may offer improved contamination resistance in harsh environments.
