Chromium Steel Machined Inner Ring For Needle Bearings, Inch Size
A machined inner ring is a component commonly used in bearing assemblies. Precision ground inner ring provides a hardened raceway for the rollers when used with an unhardened shaft. The ring contains an oil hole and annular groove for re-lubrication of the bearing and can be used with both CAGEROL and GUIDEROL bearings or can be utilized as a bushing in plain bearing applications.
The purpose of a machined inner ring is to provide a smooth and precise track for the rolling elements. It ensures proper alignment, reduces friction, and enables efficient transmission of rotational or linear motion. The precise machining process results in a high-quality surface finish and dimensional accuracy, which contributes to the overall performance and longevity of the bearing.
Machined inner rings are often used in various types of bearings, including ball bearings, roller bearings, and needle bearings. They are crucial components in machinery and equipment across different industries, such as automotive, aerospace, industrial machinery, and power transmission.
The benefits of using a machined inner ring include improved load-bearing capacity, enhanced rotational accuracy, and reduced wear and tear. The precise machining allows for better distribution of loads, reduces stress concentrations, and promotes smoother operation of the bearing.
MOUETTE offers more interchange tables, such as mcgill machined inner rings, ina inner rings, koyo inner rings, torrington inner race, skf inner ring.
We offer both standard and customized inner bushing, in High-Alloy Bearing Quality Steel 100Cr6, Stainless steel 440C.
