What are roller bearings used for?
Roller bearings are used in all main shaft and auxiliary drive shaft applications to support pure radial load, and allow for axial shaft elongation due to temperature changes with no additional load effect on the bearing.
What do the letters mean on bearings?
The number and letter combinations have the following meaning: The first digit or letter or combination of letters identifies the bearing type and eventually a basic variant. The first digit indicates the width or height series (dimensions B, T or H). The second digit identifies the diameter series (dimension D).
What is the application of bearings?
Thrust ball bearings are for applications with primarily axial loads. They can also handle shaft misalignment. Additionally, the bearings excel in high-speed applications for the automotive and aerospace industries and spindles, machine tool tables, fluid control valves.
Why do needle bearings fail?
As shown in Figure 2, the prime reason roller bearings fail to reach life expectancy is due to lubricant contamination from particles. To the naked eye, a lubricant sample might look clean, but in fact, contains tiny wear-causing contaminants, including dirt, dust, sand, metal shards and other elements.
Do you grease needle bearings?
Needle bearings are usually lubricated with grease, but oil or oil-mist lubrication is preferred for heavy-duty or high-speed applications. Many light-duty bearings never require relubrication, but high loads or speeds demand it.
