Description of πŸ’¨ High-Speed Rotational NSK Non-Contact Clearance at 17000 RPM

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. Non-contact seals fasten to outer ring on both sides of the bearing to keep lubricant in and contaminants out.

Sloppy performance, avoid at all costs

This bearing is a complete disaster. Industrial and Scientific claims are far-fetched. My analysis of this product showed that it is anything but reliable. The only positive aspect is that it is affordable, but that doesn't make up for its sloppy performance. I wouldn't use this bearing even if it were given to me for free. Steer clear of this one.

Pros
  • Ensures accurate and precise measurements
Cons
  • May require a skilled technician to operate effectively

quality stock. Highly recommend

High quality NSK bearing I used this to overhaul my 8 year old Pentair 2 HP pump. I have compared them to Nachi bearings (Japanese) which are equal in static and dynamic load capacity, but the NSK bearing is rated at 17,000 rpm versus 12,000 rpm for Nachi. It was easy to buy them for about the same price. With these bearings, I could hear the pump getting louder over time through my bedroom wall. Now I can't say it works at all (like when it was new).

Pros
  • Excellent construction
Cons
  • Crumpled packaging

Country of origin unknown

I replaced the bearings on a brand new Polaris PB4-60 pump motor before putting it into service. This is a Century brand pump made in China. I thought the OEM bearings were cheap Chinese ones prone to early failure and they were Japanese. However, there was no indication of the country of manufacture either on these bearings or on the packaging. What surprised me was that the new bearings I removed from the new motor were NSK branded and China stamped. So, apparently, NSK bearings cannot be…

Pros
  • certified
Cons
  • cable is shorter than other picks
