Product catalog summary

Introduction
NTN-SNR provides a range of super precision bearings that integrate Japanese expertise with European service, focusing on high performance, quality, low maintenance costs, and productivity.

Product Range
The NTN ULTAGE Super precision bearing range includes the 7000 and 7900 high precision series, featuring contact angles of 15° and 25°, normal preload, universal matching, and P42 precision.

Design and Features
The ULTAGE label represents a standardized range of spindle bearings optimized for performance. Key features include a polyamide molded cage for reduced heat generation and higher speed limits, improved grease and air-oil lubrication, and an optimized internal design for high speed, rigidity, and axial load capacity.

Benefits
The bearings enhance productivity, reliability, and efficiency through higher rotational speeds, longer service life, and a combination of high speed and rigidity.

Technical Specifications
The document details specifications for various models, including dimensions, contact angles, load ratings, and limiting speeds. For instance, the 7000UCG/GNP42 model has a bore diameter of 10 mm, a contact angle of 15°, and a dynamic load rating of 5.3 kN.

Conclusion
NTN-SNR's ULTAGE range is designed for high-performance machine tools, offering a balance of speed, precision, and durability.

Overview
This document provides detailed specifications and technical data for NTN Ultage Super Precision Bearings, highlighting dimensions, load ratings, and performance characteristics.

Specifications
Bearings are categorized by part numbers such as 7900UCG/GNP42 and 7900UADG/GLP42, with bore diameters from 10 to 130 mm. Contact angles of 15° and 25° affect load distribution and performance.

Technical Data
Each bearing model includes boundary dimensions, contact angle, basic dynamic and static load ratings, and limiting speeds for grease and oil lubrication. Preload and rigidity values indicate stiffness and load capacity.

Performance Characteristics
Dynamic and static load ratings in kN determine the bearing's capacity to withstand operational loads. Limiting speeds are provided in min-1 for maximum operational speed under grease and oil lubrication.

Additional Information
The document mentions sealed versions, high-speed, super-high-speed, and eco-friendly versions, emphasizing the combination of Japanese expertise with European service.
