4208‑B‑TVH Double‑Row Deep Groove Ball Bearing 40*80*23mm Nylon Cage For Industrial Motors

Product Overview
4208‑B‑TVH is open‑style double‑row deep‑groove ball bearing fitted with glass‑fiber reinforced nylon cage. Its dual‑ball‑row structure supplies stronger radial and bidirectional axial load capacity than single‑row bearings. The durable GCr15 bearing‑steel raceway delivers quiet, stable high‑speed running. It suits a wide range of general‑speed transmission, pump and motor‑driven machinery.
