450kg YRTS150 Slewing Rotary Table Roller Ring Bearing High Precision

YRTS Series bearing introduction:

YRT turntable bearing is a kind of outer ring spinning, inner ring supporting slewing mechanism, mainly divided into YRT, YRTS YRTM type three series, the three series of bearing has the same installation size, internal structure is different, the performance is similar.

YRTS series are composed of three columns of roller bearing, two columns axial roller to ensure stability of the axial bearing capacity, a list of the radial roller to ensure bearing can bear radial force and overturning moment effect, suitable for axial bearing slewing mechanism.

YRTS turntable bearing is mainly used for nc machine tool manufacturing industry, as its core component, China YRT accuracy of turntable bearing parameter standard also will be subject to international manufacturers.

Since entering the 21st century, especially as the country "high-end CNC machine tools and basic manufacturing equipment" special startup, greatly promote the development of the machinery and equipment industry, the high-speed, precision, composite, intelligent machine got further speed up the development process

YRTS bearing bearings type and size:

YRTS series (comply  with Germany INA/FAG code number)main sizes:

YRT bearing bearings are suitable for axial and radial bearing.

High slant stiffness and high precision, suitable for rotary table, chuck and iron tool head and bearing configuration in measurement and experiment. This type bearing has high requirements for matching equipment parts. The torque of the mounting screw must be controlled during installation. It is mainly used in high-precision CNC turntable, dividing head, military radar, aviation, aerospace and measurement and testing.

1. To coordinate structure is asking to see the picture, fixed by screw protect bearing parts, centering more easily to install, installation can loosen the set screw, after installation of fixed screw should be tightened or it is better to replace screw positioning screw.

2. L- section ring 2 can be installed with or without additional support ring

A) without support ring, bearing code YRT

B) with L- section ring support ring, bearing code YRT... The entire surface of the VSP, l-section ring must be supported.

3. The assembly force can only be passed through the mounting bearing ring, and must not pass through the rolling body.
Screw tightening order 1-6
Screw tightening order 1-6

4. The positioning screw applies torque wrench in the form of cross - crossing to tighten up to see image 2

(right).

5. Do not separate or exchange bearing parts for installation and removal.

6. The starting friction torque is 3~3.5 times the friction torque of the bearing in the dimension table
