Introduction of LYHY crossed roller slewing bearings
LYHY is a professional manufacturer in slewing ring bearings since 1993. We can also design and make other standard and non-standard ball bearings, roller bearings and precision bearings as per customer's different technical requirements.
Slewing bearing is also called slewing ring, slewing ring bearing, turntable bearing, and rotary bearing.
With the cross roller Ring, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90° groove, separated from each other by a spacer retainer.  This design allows just one bearing to receive loads in all directions including, radial, axial and moment loads. Since the Cross-Roller Ring achieves high rigidity despite the minimum possible dimensions of the inner and outer rings, it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines.
 

Structure:
Cross roller slewing bearing has three different types:
Cross roller ball slewing bearing with no gear
Cross roller ball slewing bearing with external gear
Cross roller ball slewing bearing with internal gear



 
Features
Cross roller slewing ring bearings have following features:
1. High precision: cross roller bearings can be made high precision bearings, at P4, P2.
2. High rigidity: These series roller bearings are with preload.
3. High load capacity: This series roller bearing can support axial load, radial load, and tilting load.
4. Small volume: this series roller bearing can save space for the machine.
 

Quality Control Process of LYHY slewing bearings

Application
Cross roller slewing rings are widely applied in the precision rotary table, rotary joint of manipulator, medical equipment, and measuring instrument etc



Packaging Details:
1. Bearing surface is covered with the anti-rust oil first; And then wrapped with the plastic film;
2. And then packed with Kraft paper and professional belts;
3. At last, with wooden box totally at the outer packing to invoid the rust or the moist;
4. We can depend on the customers demand to be packed;

INSTALLATION OF LYHY SLEWING BEARINGS

Preparation:
Make sure that the model is correct and slewing bearing isn't damaged during transportation.
2.  Check the appearance and rotational state of the bearing, such as rotational precision clearance, rotating flexibility, seals position, lubrication grease etc.
3.  The installation datum plane and bracket installing plane should be clean, grease, burr, paint and other foreign body should be wiped off.

Installation:

1. The screws in the installing plane should be fit with the mounting holes in the slewing bearing
2.  The slewing bearing has a soft zone marked with an "s" on the upper surface, when installing the bearing, it is important to ensure that this area is placed in a non-load or infrequent load zone.
3.  When the bearing is placed on the supporting frame work it is important to check the interface between these two surfaces. This check should be carried out with the insertion of feel gauges between the two surfaces. If a gap should exist then it is recommended to plane/resurface the effective area so as to remove the gap.
4.  Install slewing bearing with high strength screws, and choose appropriate strength bolts. All bolts are required to be tightened evenly. The sequence of this tightening process is shown in Pic. Welding of bearing is not allowed, in the event of welding any adjacent parts, heat transfer shall be avoided so as to cause the bearing to become deformed or change the hardness.
5.  After installation, the bearing should be rotated to check for smooth operation and any emission of unusual noise. If either of the aforementioned are noted, then the bearing should be adjusted to eliminate them. The teeth of the largest run-out are coated with green paint.
