LTZC roller slewing bearings include single-row crossed roller slewing bearings, single-row four-point contact ball slewing bearings, double-row eccentric ball slewing bearings, three-row cylindrical roller slewing bearings, and ball-roller combination slewing bearings.

Single-row crossed roller slewing bearings, with their cylindrical rollers arranged in a 90° cross pattern, are the most commonly used type of roller slewing bearing and are suitable for robot joints, precision turntables, medical equipment, and radar.

Single-row four-point contact ball slewing bearings are light-load bearings where the rolling elements and raceways form four-point contact, creating friction and generating rotational motion. They are commonly used in construction machinery, cranes, excavators, and port machinery.

Double-row ball slewing bearings offer higher load-bearing capacity, can withstand greater overturning moments, and are lighter and less expensive than three-row roller bearings. They are used in large cranes, port cranes, tunnel boring machines, and metallurgical equipment.

Three-row cylindrical roller slewing bearings are the strongest load-bearing roller slewing bearings and are commonly used in heavy-duty cranes, offshore platforms, large tunnel boring machines, and mining machinery. The rolling elements of a ball-roller combination slewing bearing are a combination of steel balls and cylindrical rollers. This combination combines the low friction and high speed of ball bearings with the high load capacity of roller bearings, making it suitable for high-speed and heavy-duty precision rotary tables.
