Rolling Bearing Lubrication for Critical Running Conditions

The grease service life for rolling bearing lubrication depends on the selection of grease, type of bearing, working conditions and environmental influences. The basis for the grease service life calculation can be seen in the generally accepted diagram (Figure 2). This diagram contrasts what is often called a "general-purpose grease" (a mineral oil-based lithium grease, Grease A) with the

Thrust bearing

Thrust roller bearings are used to withstand combined axial and radial loads that are dominated by axial loads, but the radial load must not exceed 55% of the axial load. Compared with other thrust roller bearings, this kind of bearing has lower friction factor, higher speed, and has self-aligning performance. The rollers of type 29000 bearings are asymmetrical spherical rollers, which can

What Are Roller Bearings?

Roller bearings — also known as rolling-element bearings — are similar to ball bearings in that they are designed to carry a load while minimizing friction. However, roller bearings transmit loads using cylinder rolling elements, rather than balls, to maintain the separation between moving parts of the bearing. These versatile bearings can contain single or multiple rows of rolling
