NTN Polylube Bearing 6201ZZ/LP03 1unit

[Lubricant leakage is small]Since the polylube becomes solid after heat treatment, it retains a large amount of lubricant inside.This lubricant is gradually supplied to the rolling surface due to the heat generation and centrifugal force of the bearing, which reduces the leakage of the lubricant.Therefore, it prevents pollution of the surrounding environment compared to general lubricating grease.[Good lubrication characteristics]Even when strong vibration or large centrifugal force acts on the bearing, the lubricant does not leak easily, and the polylube is solid and does not emulsify and flow out even if water infiltrates, so the lubricating characteristics are better than general lubricating grease. Is excellent.[Bearing torque]With the spot pack specification, the poly loop is not agitated like grease, so there is almost no agitation resistance and a reduction in bearing torque can be expected.[Seal effect]Polylube acts as a barrier against invading substances (moisture, dust, etc.) from the outside, but it is not sufficient as a sealing device, so when using it in places where sealing properties are particularly required, contact type rubber seals (deep groove ball bearings, etc.) We recommend using a bearing unit) or a separate seal (other bearings).
