DESIGNATION GUIDE型号规则
Read and confirm the complete designation.识别并确认完整型号。
The flange arrangement is part of the basic designation; also confirm clearance, cage and internal design suffix.挡边形式属于基础型号的重要组成部分，同时需确认游隙、保持架及内部设计后缀。
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。23 matching basic designations 个匹配的基础型号

Boundary dimensions are a selection aid, not a final quotation specification. Load rating, speed, mass, fillet and calculation factors are issued only after the exact construction and suffix are confirmed.安装尺寸用于初步选型，不等同于最终报价规格。额定载荷、转速、质量、倒角及计算系数仅在完整结构和后缀确认后提供。
TECHNICAL DATA REQUEST详细参数获取
Need load, speed, temperature or accuracy data?需要载荷、转速、温度或精度参数？
Send us the complete model, required quantity and operating condition. Our team will confirm the applicable technical sheet against the final material, seal, clearance and manufacturer series.请提供完整型号、需求数量和使用工况。我们会根据最终材质、密封、游隙及制造商系列，核对并提供适用的技术资料。
SELECTION FACTORS选型要点
Information that defines the final specification.决定最终规格的关键信息。
The required values depend on size, construction, operating condition and the complete designation.所需数值取决于尺寸、结构、实际工况及完整型号。Boundary dimensions: bore, outside diameter and width边界尺寸：内径、外径和宽度
Basic dynamic and static load ratings基本额定动载荷与静载荷
Reference and limiting speeds参考转速与极限转速
Internal clearance and preload内部游隙与预载要求
Tolerance and precision class公差与精度等级
Seals, shields, cage and lubricant密封、防尘盖、保持架与润滑
Fit, temperature and contamination配合、温度与污染环境
