What is a turntable bearing

The turntable bearing is a kind of bearing that can simultaneously withstand axial load, radial load, overturning moment and other comprehensive loads. It is a precision bearing with a special structure that integrates support, rotation, transmission, and fixing functions.This bearing basically adopts a negative clearance pre-tightening design to ensure high rigidity and rotation accuracy of the bearing.

Generally, the inner and outer rings of the slewing bearing have mounting holes, lubrication holes, and sealing structures, which are suitable for different installation and use requirements of various equipment under precision working conditions.The slewing bearing has the characteristics of compact structure, high rotation accuracy, and easy installation and maintenance.

The models and working principles of turntable bearings are also different.Turntable bearings are mainly composed of inner and outer rings, rolling elements, and cages, among which the rolling element is the key component.It usually uses steel balls, cylinders, cones, etc., which roll to bear weight and rotational force.When the turntable bearing rotates, the rolling element rolls between the inner and outer rings, thus enabling the entire mechanical equipment to complete rotational motion.

In addition, the turntable bearing also has a self-lubricating function, which can form a very thin oil film between the inner and outer rings and rolling elements, thereby reducing friction and wear and extending the life of the bearing.

Turntable bearings mainly include YRT turntable bearings, ZKLDF turntable bearings, and cross roller bearings.These three series of bearings have the same installation dimensions, but their internal structures vary and their performance is similar.

Features of the turntable bearing

Withstanding large radial and axial loads: Compared to other bearings, the turntable bearing can withstand large radial and axial loads, and can also ensure high accuracy and stability while withstanding the loads.

Flexible rotation: The turntable bearing rotates flexibly with low friction, enabling large-angle rotation and oscillation with high rotational accuracy.

Long service life: The turntable bearing uses high-quality materials and precision machining processes, providing long service life.

Compact structure: The turntable bearing has a compact structure, small size, and easy installation, which helps to save space and improve rotation efficiency.

High precision: The raceway and ball of the turntable bearing are processed with high precision, enabling high-precision angle and position adjustment.

High rigidity: The turntable bearing is made of high-quality materials and has high rigidity, capable of withstanding large loads and shocks.

High anti-friction performance: The rolling friction between the ball and the raceway of the turntable bearing has a low coefficient of friction, which can reduce energy loss and wear.

High-speed performance: The rolling friction between the ball and the raceway of the turret bearing has a high speed of motion and can meet the requirements of high-speed machine tools.

Corrosion resistance: The turntable bearing is made of high-quality materials and has good corrosion resistance, making it suitable for harsh working environments.
