When should grease be used for bearings? Grease lubrication is generally restricted to relatively slower-speed applications due to reduced capability for frictional heat dissipation as compared with that of oil. The advantages of grease over … [Read more...] about Friday Bearing Fast FAQ 10:

How do you ensure a proper fit between the shaft and the inner bearing ring? In order for a ball or roller bearing to perform satisfactorily, the fit between the inner ring and shaft must be suitable for the application. For example, too loose a … [Read more...] about Friday Bearing Fast FAQ 9:

How do radial vs. thrust loads affect ball bearing selection? Load type, magnitude and direction of loads are all key in determining the proper type of ball bearing. Specifically, if a ball bearing’s load requirements are only to be able to carry … [Read more...] about Friday Bearing Fast FAQ 8:

Are bearings with fluoro rubber seals safe? Fluoro rubbers have high thermal, chemical, ageing, ozone, wear and gas permeability resistance, and are safe as long as the material is not over-heated. However: At temperatures above 300 °C (570 … [Read more...] about Friday Bearing Fast FAQ 7:

What is a minute of arc (MOA) and why is it important for bearings? A circle is divided into 360° (angular segments) around the circumference and each degree is further divided into 60 minutes (smaller angular segments). A minute of arc is a unit … [Read more...] about Friday Bearing Fast FAQ 6:

Why are multiple single-row taper roller bearings sometimes paired together? Single row tapered roller bearings can accommodate radial load and axial load in one direction. Two single row tapered bearings are paired in opposing directions to each … [Read more...] about Friday Bearing Fast FAQ 5:

How do you remove a bearing from a housing? Since bearings with interference fits can be easily damaged during removal, precautions to prevent damage during removal should be taken. To ease removal and avoid damage, proper tools and procedures … [Read more...] about Friday Bearing Fast FAQ 4:

How do dynamic bearing loads affect bearing life? Bearings are subjected to certain levels of repeated stress or dynamic loading on their raceways and rolling elements during operation under proper loading, appropriate mounting and sufficient … [Read more...] about Friday Bearing Fast FAQ 3:

How do you mount a single row tapered roller bearing? When mounting a bearing the press fit should be on the rotating ring and a clearance fit on the stationary ring to allow for temperature expansion. Methods used for mounting are as follows: 1.) … [Read more...] about Friday Bearing Fast FAQ 2:
