Description

• Characteristics of THK linear guide SR typeCompared with the 45 ° touch structure, the THK linear guide SR kind has the following outstanding characteristics. By utilizing the characteristics of those THK linear guides, machines and devices with increased precision and tension could be manufactured.Differences in rated load and repair life of THK linear guidesDue to the use of a 90 ° touch structure within the THK linear guide SR type, there could also be variations in rated load or carrier lifestyles compared to using a forty five ° touch structure. Compared with the product with a 45 ° contact structure, the THK linear guide SR type has solely 70% of the weight performing on the HSR form when subjected to the same radial load in response to the same ball diameter. This outcome shows a distinction of more than two times within the provider life of the THK linear guide SR type.Differences in Accuracy of THK Linear GuidesIf there's a machining error (grinding error) within the THK linear handbook music or THK handbook slider, it will impression the walking accuracy. Assuming the machining error of the rolling surface is Δ, the radial direction error of the 45 ° contact constitution (HSR type) will be 1.4 occasions greater than that of the 90 ° touch constitution (SR type). In addition, in the horizontal direction, the horizontal error of the 45 ° contact structure might be 1.22 instances that of the 30 ° touch structure.The distinction in rigidity of THK linear handbook railThe 90 ° touch constitution used in the THK linear guide SR variety additionally differs in tension from the forty five ° touch structure.When an identical radial load P is applied, the displacement of THK linear instruction manual SR sort within the radial path is barely 56% of that of the forty five ° contact constitution product. Therefore, when excessive tension is needed within the radial direction, using THK linear guide SR variety is more advantageous.SummaryTherefore, the THK linear guide SR sort with a ninety ° contact structure is best suited for locations mainly plagued by radial loads, places that require radial rigidity, or areas that require strolling accuracy in the up, down, left, and appropriate directions.However, when the anti radial load, lateral load, or moment is large, it is recommended to use HSR kind THK linear guides with a forty five ° contact constitution (4-direction equal load type).
