Screw compressors are used in environments where they are exposed to such chemicals as compressor oil, refrigerants, and ammonia gas. Consequently, bearings for screw compressors must be highly resistant to oil and heat. NSK bearings for screw compressors feature polyphenylene sulphide (L-PPS) plastic cages that offer superior chemical resistance and deliver high performance regardless of the operating environment.

Product Lists

• High Load Capacity Angular Contact Ball Bearings

  

  A high load capacity bearing for screw compressors that adopts a superiorly chemical-resistant polyphenylene sulphide (L-PPS) plastic cage.

  Features

  • This bearing adopts an L-PPS plastic cage that features heat-resistant properties in addition to a cage strength that remains unaffected even when exposed to chemicals including compressor oil, refrigerants, or ammonia gas.
  • Internal geometry of the bearing has been optimally designed to provide increased load carrying capacity.
  • The newly designed internal geometry also increases axial load limits and load capacity.
  • The ball guided cage design facilitates improved lubrication of the bearing interior.
• 

  High Load Capacity Cylindrical Roller Bearings
