Profile Rail Components
Profile Rail Components
The document provides a comprehensive overview of the MR, AR, and HR series bearing designs by LINTECH. These designs feature two or four rows of re-circulating balls at a 45-degree contact angle, enhancing rigidity under moment and torsional loads. Larger ball sizes improve load capabilities, offering equal loading in all directions and smooth motion. Key features include a dust-proof design, self-lubrication options, and materials such as stainless steel and alloy steel for bearings, rails, and balls.
The document details specifications for block height and width variance, emphasizing the importance of mounting surface accuracy for optimal performance. The MR, AR, and HR series have specific parallelism and preload requirements to enhance stiffness and torsional resistance.
Static and dynamic load capacities are discussed, with recommendations for safety factors to prevent premature failure due to unforeseen forces. Guidelines for calculating the expected travel life of bearings based on load capacities and safety factors are provided.
Proper lubrication is essential for long-term operation, reducing friction, wear, and oxidation. The MR12 model includes a self-lube feature, while the AR15 and HR25 models offer it as an option. Lubrication intervals should not exceed one year.
Detailed technical specifications for each series are provided, including dimensions, material types, maximum rail lengths, speed and acceleration limits, and load capacities. Conversion tables for various units of measurement are also included.
The document provides a list of conversion factors for various units related to mechanical motion control, such as ounce-inches2, pound-inches2, and gram-cm2. It includes conversion to degrees, inches, feet, microns, and other units.

Technical Reference MR, AR & HR Series Recommended Linear Bearing Dynamic Safety Factors Linear Bearing Load Capacities To ensure proper life, external forces should never come close to the static load rating. Repeated forces at or near the maximum rating can fatigue the elements causing premature failure. Thus, a safety factor should be considered to account for these forces. Also by using a safety factor, extra unforeseen loads that arise within an application sometime in the future, would not affect the bearing and rail chosen.
