Ball bearing advice needed
I need to replace the bearing races on the mower's grass-collector brush
bar. The mower manufacturer specifies 6203 ZZ bearings (with metal shields both sides) but I'm wondering whether those with rubber seals (6203 2RS) might be better at keeping out the crud. Do we have any bearing experts who could advise? |

Ball bearing advice needed
I'd have thought those might rot. You are lucky to have bearings!
Sounds a bit like the start of a Monty Python sketch, When I were young it just had a spindle running in two holes laddie. Brian -- -- This newsgroup posting comes to you directly from...

Brian Rubber seals on "everyday" bearings are likely to be nitrile, for resistance to the mineral oil in greases. It's slightly more weather resistant than the cheapest natural rubber or its synthetic equivalent. Not especially UV or ozone resistant but then not necessarily particularly exposed either. |

I thought nitrile handled heat better too? Slightly but not all that much. |
