E3-03 Bitzer Bearing NUP210 For Bitzer Refrigeration Compressor

The E3-03 NUP210 cylindrical roller bearing is a core wearable rotating support component for Bitzer semi-hermetic refrigeration compressors. Installed at both ends of the compressor crankshaft, it bears heavy radial loads generated during compression operation and limited bidirectional axial thrust. The split NUP structure enables convenient assembly and disassembly during compressor overhaul.

Manufactured from high-purity bearing steel with precision grinding process. Optimized roller contact design improves load distribution, effectively avoid local stress concentration. Suitable for continuous long-time operation under variable speed and variable load working conditions of transport refrigeration and bus air conditioning compressors. Stable performance under fluctuating temperature inside compressor housing.
