Precision rotary tables are common in automated testing stations, optical inspection equipment and small CNC machines. The rotary support needs high rotation accuracy, strong rigidity and compact outline at the same time. In most cases, two sets of angular contact bearings can meet basic demands, but they require complicated installation and preload adjustment.

Crossed roller bearings offer a more practical alternative. Cylindrical rollers are arranged in a cross layout inside the bearing. A single unit can withstand radial load, axial load and tipping torque simultaneously. Manufacturers can shorten assembly time and reduce the overall thickness of rotary platforms.

Some customers often confuse crossed roller bearings with thin section bearings. We always remind clients: pick crossed roller bearings if high rigidity and heavy load are priorities; choose thin section bearings when lightweight and ultra-narrow installation space is your main concern.

Lanbo Bearings supplies multiple series of crossed roller bearings with different accuracy classes. We can finish preload processing before delivery to help customers skip secondary adjustment during assembly. Send over your working condition parameters for suitable bearing selection.
