  • Product Description

YRT turntable bearings:

YRT turntable bearings are a type of rotating mechanism with an outer ring for rotation and an inner ring for support. They are mainly divided into three series: YRT type, YRTS type, and YRTM type. These three series of bearings have the same installation dimensions, but have different internal structures and similar performance. The YRT series bearings are composed of three rows of rollers, with two rows of axial rollers providing stable axial bearing capacity and one row of radial roller bearings capable of withstanding radial forces and overturning moments, making them suitable for axial bearing rotary mechanisms. YRT turntable bearings are mainly used in the CNC machine tool manufacturing industry.

The YRT turntable bearing consists of a thrust/radial shaft ring, a thrust washer, two needle roller cage components, and a set of radial cylindrical rollers. The seat ring and shaft ring have evenly distributed installation screw holes. This type of bearing has high axial and radial load-bearing capacity. High tilt stiffness and high precision. Suitable for rotary workbenches, chucks and milling heads, as well as bearing configurations in measurement and experimentation. This type of bearing also has high requirements for the matching equipment parts. During installation, it is necessary to control the tightening torque of the installation screws.

Scope of application: Widely used in precision rotary tables, CNC turntables, vertical grinders, indexing heads, hobbing machines, milling machines, workpiece shafts and other precision devices.

YRT turntable bearing installation part

1. The requirements for the matching structure are shown in the figure on the right. During transportation, the fixing screws protect the bearing parts. In order to facilitate centering installation, the fixing screws can be loosened during installation. After installation, the fixing screws should be tightened again or replaced with positioning screws.

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

a) Without a support ring, bearing code YRT

b) The bearing code YRT... VSP is used to support the ring with an L-section ring, The entire surface of the L-section ring is supported.

3. Assembly force can only be transmitted through the installed bearing rings and must not be transmitted through the rolling elements.
