ZYS 6203 deep groove ball bearing
By Luoyang Bearing Research Institute Co., Ltd. (ZYS)
ZYS 6203 is a deep-groove ball bearing with a 17 mm bore, 40 mm outside diameter and 12 mm width. Compare its listed load ratings, mass and closure options.
Model and installation envelope
The 6203 base designation has a d × D × B envelope of 17 × 40 × 12 mm. The three dimensions are shown separately below so the shaft, housing and available axial space can be compared without confusing their order.
Before selecting a suffix
Closure options describe alternative executions, not extra included components. Give the supplier the complete bearing designation, operating conditions and required closure when requesting the current drawing. Listed basic load ratings are catalogue reference values, not a direct allowable machine-load recommendation.
