Definition Differences

Rolling bearings refer to bearings where the rolling elements roll on the raceways; sliding bearings operate under sliding friction.

Bearing Category Differences

Japanese Shaft Research Seiko ZNY's rolling bearings can be classified based on structure type and size. Structurally, based on the type of rolling element, they can be divided into ball bearings and roller bearings. Based on whether they have self-aligning capabilities, they can be divided into self-aligning bearings and non-self-aligning bearings. Based on whether the parts are separable, they can be divided into separable and non-separable bearings. Size-wise, they can be categorized into miniature bearings, small bearings, medium-small bearings, and large bearings.

The classification of sliding bearings is also diverse. One classification is based on the state of the lubricant, dividing them into semi-solid state lubricated bearings and liquid state oil-lubricated bearings. Another classification is based on the direction of the load they bear, dividing them into thrust sliding bearings and centripetal sliding bearings.

Functional Feature Differences

Rolling bearings are characterized by a low friction coefficient, small starting friction torque, relatively simple installation and disassembly, and ease of lubrication. For the same shaft diameter, their width is smaller, allowing for more compact axial dimensions in mechanical equipment.

Sliding bearings, on the other hand, have a longer service life compared to rolling bearings, stronger vibration resistance and load capacity, and simpler structures. However, their drawbacks include greater friction, more wear, and poorer precision retention.

Application Scenario Differences

Generally, for Japanese Shaft Research Seiko ZNY rolling bearings, which have low friction and generate less heat, they are more suitable for high-speed rotating scenarios.

For Japanese Shaft Research Seiko ZNY sliding bearings, capable of bearing larger loads, they are suitable for scenarios with heavy loads, compact structural requirements, and smaller radial dimensions.

Both rolling bearings and sliding bearings have their advantages. The specific choice should be based on factors such as working conditions.
