DESIGNATION GUIDE型号规则
Read and confirm the complete designation.识别并确认完整型号。
Confirm ring material, ball material, cage, seal, precision, clearance and operating medium before selecting a ceramic solution.选择陶瓷轴承前需确认套圈材料、滚动体材料、保持架、密封、精度、游隙及工作介质。
Manufacturer suffixes are not automatically interchangeable. ZOFANG verifies the full designation, drawing and current technical catalogue before issuing final data.不同制造商的后缀不能默认互换。轴方会在提供最终数据前核对完整型号、图纸及当前有效的技术目录。
MODEL DATABASE型号数据库
Search the range by designation or dimensions.按型号或安装尺寸快速查询。
Dimensions in mm. Select a suffix only after checking sealing, clearance, accuracy, lubrication and operating conditions.尺寸单位为 mm。密封、游隙、精度、润滑及工况确认后，再确定完整后缀。9 matching basic designations 个匹配的基础型号
