Product catalog summary

Overview: This document is a technical specification sheet for single row cylindrical roller bearings produced by THB Bearings Co., Ltd. It provides detailed information on various bearing models, including their dimensions, load capacities, speed ratings, and mass.

Principal Sections:

Specifications: The document lists the principal dimensions of the bearings, including diameter (d), outer diameter (D), and width (B). It also specifies the basic dynamic (C) and static (C0) load ratings, fatigue load limit (Pu), and mass of each bearing model.
Speed Ratings: Each bearing model is provided with a reference speed and a limiting speed, indicating the maximum operational speeds under standard conditions.
Designations: The bearings are categorized under different designations such as NU, NJ, NUP, and N, which refer to specific types of cylindrical roller bearings with varying cage designs and applications.
Alternative Cages: Some bearings have alternative standard cage options, which are indicated in the document.

Key Data Summary:

The document includes a comprehensive table listing various bearing models with their respective specifications.
Dynamic load ratings range from 11.875 kN to 361 kN, while static load ratings range from 9.69 kN to 380 kN.
Mass of the bearings varies from 0.047 kg to 6.4 kg, depending on the model.
Speed ratings indicate that the bearings can operate at speeds ranging from 4,000 r/min to 26,000 r/min.

Conclusion: This specification sheet serves as a detailed guide for selecting the appropriate cylindrical roller bearing based on load requirements, speed capabilities, and dimensional constraints. It is essential for engineers and procurement specialists in the manufacturing sector to ensure optimal performance and compatibility in machinery applications.

Overview: This document provides detailed specifications for single row cylindrical roller bearings manufactured by THB Bearings Co., Ltd. It includes principal dimensions, basic load ratings, fatigue load limits, speed ratings, and mass for various bearing models.

Principal Dimensions: The dimensions are specified in millimeters (mm) and include the diameter (d), outer diameter (D), and width (B) of the bearings. These dimensions are crucial for ensuring compatibility with machinery and equipment.

Basic Load Ratings: The document lists dynamic (C) and static (C0) load ratings in kilonewtons (KN). These ratings indicate the bearing's capacity to withstand loads during operation and at rest, respectively.

Fatigue Load Limit: The fatigue load limit (Pu) is provided, representing the maximum load the bearing can endure without experiencing fatigue failure over its lifespan.

Speed Ratings: Reference and limiting speed ratings are given in revolutions per minute (r/min). These ratings determine the maximum operational speeds for the bearings under standard conditions.

Mass: The mass of each bearing is listed in kilograms (kg), which is important for handling and installation considerations.

Designation: Each bearing model is identified by a unique designation code, which includes information about the bearing type and any special features or standards it adheres to.

Key Observations: The document highlights the variety of bearings available, each tailored for specific load and speed requirements. The inclusion of alternative standard cages and special designations indicates customization options for different applications.
