THB TRACK ROLLERS BEARING LR SERIES

Product catalog summary

Overview: This document is a parameter sheet for ball bearing track rollers, detailing specifications for both single-row and dual-row sealed models. It includes information on dynamic and static load ratings, fatigue limits, rotation speeds, and dimensions for various models.

Specifications:

Basic Rated Load: The document lists dynamic and static load ratings (Crw N and C0rw N) for each model, indicating the maximum load the bearings can handle under dynamic and static conditions.
Fatigue Limit Load: The fatigue limit load (Curw N) is provided, which is the maximum load the bearing can endure for a specified number of rotations without failure.
Rotation Speed: Maximum permissible rotation speeds (nDG r/min) are specified for each model, indicating the highest speed at which the bearing can operate efficiently.
Dimensions: Dimensions such as outer diameter (D), inner diameter (d), and width (C) are listed for each model, providing essential sizing information for installation and compatibility.

Model Variants:

Single-Row Seal Models: Includes models like LR 604 2RSR, LR 605 2RSR, etc., with specific load ratings and dimensions.
Dual-Row Seal Models: Includes models like LR 5200 2Z, LR 5200 X 2Z, etc., offering higher load capacities and different dimensions compared to single-row models.

Key Observations:

Models with higher dynamic and static load ratings generally have larger dimensions and mass, indicating their suitability for heavier applications.
Dual-row models typically offer higher load capacities and are designed for applications requiring greater durability and performance.
The document includes specific notes on certain models, such as those with cylindrical outer surfaces and clearance seals, which may affect their application and performance.
