Application of precision turntable

Precision turntables are widely used in the fields of machinery, aerospace, instrumentation, etc. As important equipment in these fields, their performance and accuracy directly affect the quality and performance of products in the application areas.As one of the core components of precision turntables, the selection and use of bearings plays a crucial role in the accuracy and longevity of precision turntables.

LTZC Bearings mainly used in precision turntables

The bearings used in precision turntables mainly include the following types:

Four Point Contact Ball Slewing Bearing：Four-point contact ball bearing is comprised of an outer ring and an inner ring in integral structure or split structure. The two split rings of bearings in split structure are bolted together before delivery. Usually cages or spacers can be found in four-point contact ball bearings.

Deep groove ball bearings: Deep groove ball bearings are a common type of rolling bearing with deep raceway grooves that can withstand high radial loads and can also withstand certain axial loads.Due to their high rotational accuracy, high speed performance, and low friction coefficient, deep groove ball bearings are widely used in the operation of precision turntables.

Angular contact ball bearing: Angular contact ball bearing is a type of rolling bearing that can simultaneously withstand radial and axial loads.According to the contact angle, angular contact ball bearings can be divided into different types such as 15°, 25°, and 40°.Due to their high accuracy and rigidity, angular contact ball bearings are commonly used in the support part of precision turntables to achieve high-precision angle adjustment and positioning.

Cylindrical roller bearing: A cylindrical roller bearing is a rolling bearing with cylindrical rollers, which has high load-bearing capacity and impact resistance.In precision turntables, cylindrical roller bearings are commonly used to support the spindle and transmission system to achieve high-precision rotational motion and smooth transmission.

Tapered roller bearings: Tapered roller bearings are a type of rolling bearing that can simultaneously withstand radial and axial loads, with high rigidity and load capacity.In precision turntables, tapered roller bearings are commonly used to support critical areas to achieve high-precision angle adjustment and positioning, while ensuring the stability and longevity of the turntable.

In general, there are many types of bearings used in precision turntables, but each type of bearing has its own unique performance and application range.In practical applications, it is necessary to select the appropriate bearing type and accuracy level according to different usage scenarios and requirements to ensure the accuracy and stability of the precision turntable.
