The ball deflects vertically 20 um per 12 kN, laterally 27 um per kN. The roller deflects vertically 12 um per 12 kN, laterally 17 um per kN. I don't claim this one case to represent all cases (i.e. all manufacturers), but the rollers are not quite twice as stiff in this case. In size 35, otherwise the same.

The angle of the axes between the roller and bearing determines the load capacity. The greater the angle, the more axial loads that can be supported. The contact angle in tapered roller bearings are between 10–16 degrees—however, for higher thrust-load capacities, a 30-degree contact angle is necessary.

Needle rollers have a long contact length with the guideway. Furthermore, a cage holds more needle rollers. As a result, needle roller linear guides can carry higher loads as ball and cross-roller guides with similar dimensions. High Stiffness - High rigidity: Because needle rollers are smaller in diameter, linear guides contain more of them.

But, unlike rolling elements, they can withstand shock loads and vibrations without significant damage to the surfaces. Plain bearings are also less sensitive to contamination, and rarely experience catastrophic failure. Linear guides with rolling motion. Rolling element linear guides add balls or rollers between the two bearing surfaces.

Three basic types of guide ways can support linear motion between machine tool components: rolling-element, hydrostatic and plain sliding ways. In rolling-element ways, moving elements like the table are supported on the flat, straight guide ways that are mounted on stationary elements like the bed by rolling elements, such as cylindrical rollers.

Comparison Between Roller Guideways. Mar 14, 2016· A linear guide (or linear bearing) is a mechanical element that allows relative motion between two surfaces, with one surface supporting the other, and minimum friction between the two. There are two basic types of linear guides: plain and rolling element.

A carriage mounted with a linear guideway only has to overcome rolling friction. The difference between the static and dynamic rolling friction is very small so the break-away force is only slightly greater than the motion force. Stick-slip effects are not experienced. 2.
