SSXC Series - Stainless Steel Ball Bearings with Setscrew
SMT SSXC Series are Stainless steel ball bearings with setscrews. Applicaiton is food processing machinery, cleaning equipment, LCD and semiconductor manufacturing equipment, carrier device in watery environment, other equipment used in high temperature and humidity environment.
Features
- Excellent corrosion resistance
- Improvement of workabitity to mount Fastening by setscrew allows loose fit between shaft and bore
- Secure fastening by setscrew prevents creeping between shaft and bore
- Free from abrasion powder caused by creeping Suitable for use in such environment like clean room where powder dust is not allowed
- No need for collars to fix or locate bearings
Applications
Food processing machinery, cleaning equipment, LCD and semiconductor manufacturing equipment, carrier device in watery environment, other equipment used in high temperature and humidity environment
