YRT Turn Table Bearing The Requirements For Matching Equipment Parts Are Also Higher
Nov 01, 2017

YRT Turn Table Bearing are divided into YRT type, YRTS type, YRTM type, these four types of bearings have the same installation size, the internal structure of the difference, the other ZKLDF four-point ball contact bearing its shape and structure similar performance. The YRT series has three rows of rollers, two axial bearings to ensure a stable axial bearing capacity, a radial roller to ensure that the bearing can withstand radial and overturning moment, it should be suitable for high-load rotary mechanism.

The YRT bearing consists of a thrust / radial seat ring, a thrust / torch ring, a thrust washer, two needle roller cage assemblies and a set of concentric cylindrical rollers. Rings and shafts are fitted with screw holes for mounting. This type of bearing has high axial and radial bearing capacity. High tilt stiffness and extremely high accuracy. Suitable for rotary table, chuck and iron head and measurement and experimental bearing configuration. This type of bearing on the matching equipment parts are also higher requirements. The tightening torque of the mounting screws must be controlled during installation.

Requirements for mating structures

When fixing the screws to protect the bearing parts during transport, the fixing screws can be released during installation, and the fixing screws should be tightened after installation or replace the fixing screws with the set screws.

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

a) Without support ring, bearing code YRT

b) The entire surface of the VBR, L-section ring must be supported by the bearing code YRT with the L-section ring support ring.

3. Assembly force can only be installed through the bearing rings to pass, must not pass through the rolling body.

4. Position the screws to tighten the torque wrench in a crossed form.

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

6. Start the friction torque is the scale table bearing friction torque of 3 to 3.5 times.
