THK Cross roller Slewing Ring Bearing FAQS

QHow to maintain the crossed roller slewing bearings?

AI. after 100 hours of continuous operation, the large crossed roller slewing bearings installed and put into operation shall be checked to see whether the pre tightening torque of the mounting bolt meets the requirements. In the future, the above inspection shall be repeated every 500 hours of cumulative operation. 2. Find and solve problems in time. After the crossed roller slewing bearings is installed in place, a proper amount of grease should be added. When adding grease, the bearing should be rotated while adding to make the grease evenly distributed. 3. After working for a period of time, the cross roller bearing will inevitably lose some lubricating grease. Therefore, the cross roller bearing in normal operation should be refilled with lubricating grease every 50-100 hours of cumulative operation, and the rotor bearing in high-temperature environment or dusty working conditions should be refilled with lubricating grease every 30-40 hours of operation. 4. when the cross roller bearing runs continuously for 1000 hours, it should be maintained in an all-round way. It needs to be cleaned in an all-round way. The professional personnel should remove the bearing sealing ring and clean the internal grease and dirt. Correct maintenance is very important to prolong the service life of the bearing. Correct maintenance can make the bearing run more reliably.

QWhat's the characteristic of the crossed roller slewing bearings?

A1. The cross roller bearing can be assembled in all directions of the main shaft for convenient use. 2. It can bear radial and axial loads at the same time, so it can simplify the equipment structure and reduce the weight of the mechanism. 3. The cross roller bearing has high rotation efficiency and low heat dissipation, so the consumption of lubricating grease is small. 4. It can achieve negative clearance and has high rotation accuracy. 5. High rigidity, 3-4 times stronger than the rigidity of traditional bearing. 6. High bearing capacity. The roller is in line contact with the raceway and can bear higher load.

QWhat's the classification of the crossed roller slewing bearings?

AXRB type (outer ring split type) Xre type (inner ring split type) Xru type (inner and outer ring) Xrbc type (outer ring split type) Xrbh type (inner and outer ring type) XRA type (outer ring split, ultra thin type) XRC type (outer ring split type) Xrsu08 type (integrated inner and outer ring)

QWhat's the design characteristics of the cross tapered roller bearing?

AXRT series has two rows of tapered rollers arranged vertically and crosswise on the 90 ° V-shaped hob surface through the interval keeper, which can bear the radial load, axial load and other loads in all directions. The line contact on the raceway and roller structure provides maximum rotation accuracy, high stability and greater tilt stiffness. The adjustable design of the preload extends the bearing life, increases the stiffness to the maximum and provides the minimum runout. The inertia of nylon spacer is low and the running torque is small. The components are made of surface carburized steel or ESR bearing steel, with good impact resistance.
