Crossed roller bearings:
SX are bearings for high precision applications, whose dimensions conform to ISO dimension series 18 to DIN 616. They comprise outer rings, inner rings, rolling elements and plastic spacers. The outer ring is split and is held together by three retaining rings.
Crossed roller bearings are very rigid, have high running accuracy and are supplied with normal clearance, low clearance or preload.
The bearing outer rings are easily fixed to the adjacent construction using clamping rings. Cross roller bearings are also available in a corrosion-resistant version with the special coating.
Due to the X arrangement of the cylindrical rollers, these bearings can support axial forces from both directions as well as radial forces, tilting moment loads and any combination of loads by means of a single bearing position. As a result, designs involving two bearings positions can be reduced to a single bearing position.
Circumferential speed:
The circumferential speed is dependent on the bearing(normal clearance or preloaded) and on the lubrication(grease or oil).
Sealing:
The bearings are of an open design. The sealing arrangement can be designed anywhere within the adjacent construction.
Lubrication:
SX bearings do not have an oil-based preservative but are greased; they can be lubricated using oil.For grease lubrication, a high quality lithium soap grease is suitable.
Operating temperature:
Crossed roller bearings are suitable for operating temperature from -30oC ~ +80oC.
Application:
Machine tools, precision rotary indexing tables, vertical and horizontal boring machine, vertical grinder, rotary surface grinding machine, large hobbing machine guns, radar turret, a large radio and optical telescopes, rotate the camera, steering pivot, caster, highly constrained pivot microscope, rod center pivot, rotate the bogie, welding bracket, swivel assembly fixture, industrial robots, precision rotary tables, medical equipment, measuring instruments, IC manufacturing device.

Tapered roller bearings are bearings that can take large axial forces (i.e. They are good thrust bearings) as well as being able to sustain large radial forces.
Description:
The inner and outer ring raceways are segments of cones and the rollers are also made with a taper so that the conical surfaces of the raceways and the roller axes if projected, would all meet at a common point on the main axis of the bearing.
This conical geometry is used as it gives a larger contact patch, which permits greater loads to be carried than with spherical(ball) bearings, while the geometry means that the tangential speeds of the surfaces of each of the rollers are the same as their raceways along the whole length of the contact patch and no differential scrubbing occurs. When a roller slides rather than rolls, it can generate wear at the roller-to-race interface, i.e. the differences in surface speeds creates a scrubbing action.
