YRTS high-speed rotary table bearings are high-precision bearings. They are widely used in CNC machines, industrial robot arms, etc. These high-precision equipment fields are very common, so the stability and reliability of YRTS itself is also very important.

YRTS bearings are mainly subjected to radial load by a row of radial rolling rollers, and axial loads are supported by two rows of axial rollers. Such a bearing structure will make the YRTS bearing have a relatively strong load capacity and increase The stability of the rotation. YRTS is a radial roller belt retainer, so it is more suitable for high-speed rotation. The rotating body is also very stable under the support of three rows of rollers.

YRTS high-speed rotary table bearings, its shape and structure are generally the same as the YRT type. But its internal structure is very different from the YRT series. Because of this, the limit speed of YRTS rotary table bearings will be higher than the YRT series. At the same time, the friction torque of the YRTS is relatively lower and uniform. Therefore, YRTS still has obvious advantages and is more suitable in the operation of high-speed and low-friction equipment.

YRTS are highly rigid and the bearings are also preloaded. Its accuracy is also up to P4, P2 level, YRTS is the most used in those high speed work. YRTS has been widely used in such fields as vertical grinding machines, indexing heads, and gear hobbing machines.
