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 linear polyphenylene sulphide (L-PPS) plastic cages that offer superior chemical resistance and deliver high performance regardless of the operating environment.

Features of screw compressor bearings:

• L-PPS plastic cage - The plastic cage offers superior heat and wear resistance, cage strength, and chemical stability characteristics that change little even if exposed to compressor oil, refrigerants, or ammonia gas.
• Increased load capacity  - The optimal bearing internal design with L-PPS plastic cage enables higher bearing load capacity as a result of an improved fatigue rating life.
• Improved lubrication performance - The optimal design of the cage utilizes the rolling elements to guide cages instead of by the inner or outer rings, thereby providing for more internal space and improved lubricant flow throughout the bearings.
