Product Numbering System
SCHNEEBERGER linear bearing products use a systematic type designation system for easy identification of product types, sizes, and configuration options.
Type Designation Structure
Type Designation Format
A typical type designation includes the following information:
- Product Type - R, RN, RNG, N/O, M/V, etc.
- Size Specification - Standard size code
- Accuracy Class - Standard or high precision
- Preload Class - No preload, light preload, medium preload, etc.
- Special Options - Sealing, lubrication, and other configurations
Product Type Index
| Type | Product Name | Main Applications |
|---|---|---|
| R / RD | Standard Recirculating Units | General precision linear motion |
| RN | Narrow Recirculating Units | Space-constrained applications |
| RNG | High-Load Recirculating Units | Heavy-load applications |
| N / O | Special Recirculating Units | Special application requirements |
| M / V | Linear Guideway Systems | High precision and high load |
Accuracy Class Codes
| Code | Accuracy Class | Description |
|---|---|---|
| N | Standard Precision | Suitable for general applications |
| H | High Precision | Suitable for precision applications |
| P | Super High Precision | Suitable for ultra-precision applications |
Preload Class Codes
| Code | Preload Class | Characteristics |
|---|---|---|
| C0 | No Preload | Minimum friction |
| C1 | Light Preload | Balanced rigidity and friction |
| C2 | Medium Preload | High rigidity |
| C3 | Heavy Preload | Maximum rigidity |
