Chrome three-row Cross Roller Slewing Bearing for Deck Crane

Luoyang Xinqianglian Slewing Bearing Co., Ltd.  ( Hereinafter referred to as the LYXQL) founded in 2003, is located in the ancient capital of nine dynasties Luoyang in Henan province. LYXQL is a national key high-tech enterprises and become a GEM listing company successfully on July 13,2020 (stock code "300850").

LYXQL three-row Chrome Cross Roller Slewing Bearing is an important part of Deck Crane . LYXQL three-row Chrome Cross Roller Slewing Bearing for Deck Crane has high load carrying capacity. Under same loads, three-row Cross Roller Slewing Bearing has much smaller diameters which can make the installation much compact, as different kinds of loads are supported by different races and rollers. Main applications of this kind of bearings are hoisting, mechanical handling, mining and materials handling, offshore technology and general mechanical engineering etc.

LYXQL Chrome three-row Cross Roller Slewing Bearing for Deck Crane -Main feature

1. The number of rolling elements (contact points) has increased, thereby reducing the load on each rolling element; after changing from point contact to line contact, the contact stress can be reduced and the load carrying capacity can be improved.

2. Since the radial force and the axial force are respectively borne by the two rows of rollers, the direction of the reaction force is consistent with the main direction of the load received by the support, so the contact load between the rollers and the raceway can be reduced.

3. Under the condition of bearing the same load, it is smaller than other types of supports with smaller dimensions, smaller cross-sections, and lighter weight, which can save materials and reduce material costs.

4. The raceway of the rolling ring is flat and cylindrical, making it easier to process.

5. In addition to bearing the radial force, the vertically mounted roller also has the guiding function of bearing the tipping moment.

LYXQL three-row Cross Roller Slewing Bearing satisfies the 360° requirements of construction machinery, especially cranes, stackers, ladle turrets, etc.

LYXQL Cross Roller Slewing Bearing for Deck Crane-- Maintain

1. Large three-row Cross Roller Slewing Bearing for Auto should be greased regularly. According to different types of slewing bearings, the specific grease filling time is as follows: the ball type is filled with grease every 100 hours of operation; the roller type is filled with grease every 50 hours of operation .

2. The sundries on the surface of the slewing ring should be removed frequently during use, and the sealing strip of the slewing ring should be checked for aging, cracking, damage or separation. If one of these conditions occurs, the sealing strip should be replaced in time to prevent debris from entering the raceway and the loss of grease.

3. Pay close attention to the operation of the slewing ring during use. If you find that the noise, impact, or power suddenly increases, you should stop the machine immediately for inspection until all the faults are eliminated, and disassemble and inspect if necessary.
