Country of manufacture?

They're made overseas, but they are quality. I took the seals off when I first got them to look at the bearings and the packing grease and everything was packed in really well. No issues on my install for a hot tub motor and it's been going strong for a year.

What temperature is the bearing rated to?

I put these on my boat trailer. In Yuma Az .it gets about 122° here sometimes. No problems.

Do you thnk this is durable enough for a power steering bearing?

Hi there. It should be. Honestly I never used for a power steering system but it should be. Make sure is made in US. Timken made in US is durable.

Will this fit a Polaris PB4 booster pump?

I'm not sure about that one. It could be. My subjection is, measure your Polaris PB4 booster pump first and then buy it. Tks
