worm gear slew drive FAQS

QWhat is a crossed roller bearing?

AAs their name suggests, crossed roller slides (also referred to as crossed roller bearings) are linear bearings that use cylindrical rollers—as opposed to balls—to carry a load. The rollers ride between parallel guides in which v-shaped grooves have been ground.

QWhat does a roller bearing do?

ARoller Bearings are a type of rolling-element bearing that uses cylinders (rollers) to maintain the separation between the moving parts of the bearing (as opposed to using balls as the rolling element). The purpose of a roller bearing is to reduce rotational friction and support radial and axial loads.

QWhat is slewing drive?

AThe slewing drive is a gearbox that can safely hold radial and axial loads, as well as transmit a torque for rotating. The rotation can be in a single axis, or in multiple axes together.

QWhat is slewing ring or turntable bearing ?

ATurntable bearing is a kind of large-scale bearing which can bear large axial load, radial load, overturning moment and other comprehensive loads at the same time. Generally, the bearing of turntable is equipped with mounting hole, lubricating oil and sealing device, which can meet the different needs of various main engines working under different working conditions; on the other hand, the bearing of turntable has the characteristics of compact structure, convenient guide rotation, simple installation and easy maintenance, and is widely used in hoisting and transportation machinery, mining machine, construction machinery and port. Machinery, wind power generation, medical equipment, radar, missile launchers and other large rotating devices.
