Technical Data Summary

1. Product Identification and Dimensions

Bearings are identified by unique codes often including series prefixes (e.g., NF, NJ, NU, NUP) and suffixes indicating design variants. Dimensions are consistently presented as inner diameter (d), outer diameter (D), and width (B) in millimeters, critical for ensuring proper fit in mechanical assemblies.

2. Weight Specifications

Each bearing entry includes weight in kilograms, essential for load calculations, handling, and logistics. Weights range from very light (approx. 0.005 kg) for small bearings to heavy-duty bearings exceeding 2000 kg for large spherical roller types.

3. Product Series and Variants

The catalog covers multiple bearing series with incremental size variations and design modifications. Suffixes such as -2RS, -2Z, HV, YA, EK, and others denote seals, shields, internal clearances, or cage types. Cross-referencing old and new codes supports maintenance and procurement.

4. Data Presentation and Usage

Data is organized in tabular format listing codes, dimensions, and weights, facilitating quick reference and comparison. The document serves as a technical reference for engineers, procurement specialists, and maintenance personnel for bearing selection, replacement, and inventory management.

5. Critical Observations and Recommendations

Precise dimensional data and weight information are vital for compatibility and mechanical design.
Cross-reference tables between old and new codes ensure correct identification and replacement.
Suffixes in codes indicate important design features affecting performance and installation.
Users should verify bearing variants and dimensions against application requirements.
The catalog lacks performance parameters such as load ratings, speed limits, and material specifications; these should be consulted separately.

6. Limitations

No procedural guidelines, normative standards, or installation instructions are included.
Performance characteristics and material data are absent, limiting comprehensive application design.
Some entries have missing weight data, requiring further verification.

Summary

This document is a comprehensive technical catalog from Welfare Bearing Trade Co., Ltd, providing detailed specifications of a wide range of bearing products. It focuses on physical dimensions, weights, and product codes with cross-references to support identification and replacement. The catalog is an essential tool for mechanical engineers, procurement specialists, and maintenance teams involved in bearing selection and inventory management, though additional technical data should be sourced for full application design.
