YRT Turntable Bearings Manufacturer for Precision Rotary Applications
TEDIN manufactures and supplies precision YRT turntable bearings for CNC rotary tables, indexing tables, measuring equipment and automation systems. Our axial-radial turntable bearings are designed for high rigidity, accurate rotary positioning and combined axial, radial and tilting moment load support.
What Are YRT Turntable Bearings?
YRT turntable bearings are precision axial-radial bearings for rotary tables, indexing tables and positioning axes. They combine high rigidity, running accuracy and combined load support in one compact unit.
Axial-Radial Layout
Two axial roller rows and one radial roller row support loads from multiple directions.
High Rigidity & Accuracy
Designed for stable rotary positioning under axial, radial and tilting moment loads.
Precision Rotary Units
Used in CNC rotary tables, indexing tables, inspection equipment and automation systems.
Built for Stable Precision Rotary Motion
YRT turntable bearings provide rigid support and accurate rotation for rotary tables, indexing units and positioning axes.
With axial and radial roller rows integrated into one compact unit, they help maintain stability under combined working loads.
Rigid Rotary Support
Helps reduce deflection and improve table stability during machining or positioning.
Precise Running Performance
Supports smooth rotation and repeatable positioning in precision rotary applications.
Combined Load Capacity
Handles axial loads, radial loads and tilting moments within one bearing arrangement.
Ready-to-Mount Design
Compact integrated structure simplifies installation in rotary tables and indexing systems.
Axial-Radial Structure for Combined Load Support
The integrated axial-radial design enables YRT turntable bearings to deliver stable support in compact rotary systems.
YRT turntable bearings combine two axial roller rows and one radial roller row in a single ready-to-mount unit. This structure allows one bearing to support axial loads, radial loads and tilting moments at the same time.
The preloaded bearing arrangement helps improve rigidity and reduce clearance, which is essential for rotary tables, indexing units and precision positioning axes.
Integrated mounting holes in the inner and outer rings simplify installation and help reduce the need for additional housing components.
| Structure Element | Function |
|---|---|
| Axial Roller Rows | Support axial loads from both directions and help maintain stable rotary positioning. |
| Radial Roller Row | Supports radial loads during rotation and improves overall bearing guidance. |
| Tilting Moment Support | Helps resist overturning forces generated by eccentric loads or machining forces. |
| Preloaded Design | Improves rigidity, reduces clearance and supports accurate rotary movement. |
| Mounting Holes | Inner and outer rings include mounting holes for direct installation into rotary units. |
| Compact Bearing Unit | Combines axial, radial and moment load support in one ready-to-mount assembly. |

Common questions about YRT, YRTS and ZKLDF selection, accuracy, customization and replacement.
What types of turntable bearings does TEDIN supply?
TEDIN supplies YRT and YRTS axial-radial roller bearings and ZKLDF double direction axial angular contact ball bearings for rotary tables, indexing units, positioning axes and measuring systems.
What is the difference between YRT, YRTS and ZKLDF bearings?
YRT bearings provide rigid support under combined axial, radial and moment loads. YRTS bearings are optimized for higher-speed rotary applications. ZKLDF bearings use an angular contact ball design for low-friction, high-speed rotation. Selection depends on loads, speed, rigidity, accuracy and mounting conditions.
What accuracy grades are available for turntable bearings?
Available accuracy specifications depend on the bearing series and model. Send your required dimensional tolerances and axial and radial runout limits so TEDIN can confirm the applicable grade and inspection criteria. Bearing accuracy alone does not determine the positioning accuracy of the complete rotary system.
Can TEDIN provide custom turntable bearings?
TEDIN can review custom dimensions, mounting interfaces, preload, lubrication and accuracy requirements based on your drawing and operating conditions. Available options are subject to technical feasibility and the selected bearing design.
What information is needed for turntable bearing selection?
Provide the full model designation or drawing, axial and radial loads, overturning moment, speed and duty cycle. Include mounting dimensions, required runout, rigidity, lubrication and operating temperature where available.
Can TEDIN help replace existing turntable bearing models?
TEDIN can review replacement options using the original manufacturer's full model designation and drawing. Dimensions, mounting holes, tolerances, preload, load ratings and permissible speed must be compared. Matching dimensions alone does not guarantee interchangeability.
