Description of ๐ŸŽ๏ธ NSK High-Speed Shielded Clearance with 17000Rpm Rotational Capability

Deep-groove geometry for high speeds and supporting both radial and axial loads. Single-row bearing for supporting radial loads. Normal radial internal clearance for applications that do not involve thermal expansion or atypical precision. Pressed steel cage evenly spaces the balls for even load distribution and prevents contact to reduce friction, vibrations, and noise. Shields on both sides of the bearing to keep lubricant in and contaminants out.

Buy quality from Power Transmission Products

I used these to repair my 2 year old Pentair pump. The original bearings only lasted 2 years. Well it's a joke. My old pump bearings lasted 20 years and were still very quiet. The spa guy wanted to put in a new $750 pump. I bought a seal kit and pulled the pump out, put it on my stand, installed new bearings, seals and gaskets. It cost me $30 and a full day of handwork, which I love. A year has passed and the pump is silent. Advice. Stay away from cheap Chinese bearings. Spend a few bucks moreโ€ฆ

Pros
  • Multiple competitors
Cons
  • unreliable

Best Replacement Bearings

Made in USA. I purchased a replacement kit marked NSK as a Pentair replacement based on a previous review. It's stupid to even compare them. I started returning cheap Chinese ball joints when the neighbor's pump started squeaking too. Starting with my pump. Like day and night. Although I couldn't tell my pump was working, its motor hummed like a can opener. He's very happy he saved a pack to buy me lunch. Lots of play and play in Chinese bearings and cheap oil paper. NSK all-metalโ€ฆ

Pros
  • Cool Product
Cons
  • Something Different

Significant reduction in table saw and motor noise

I was very happy with the result of replacing the table saw and motor bearings with NSK 630ZZ bearings as everything ran much quieter. Read my experiences with camps. I replaced the bearings in my 30 year old Powermatic 63 table saw for the arbor and motor (both had the same bearings). The old bearings were 6203Z. The difference is that these 6203ZZ bearings have a metal shield (not sealed) on both sides compared to the old bearing which was open on one side exposing the bearings. ZZ is muchโ€ฆ

Pros
  • Elegant design
Cons
  • Long delivery time
