Mining

With the development of modern smelting technology, international first-class bearing manufacturers have reached a relatively high level of purity in bearing steel. They not only have bearing materials that comply with ISO and ABMA standards, but also use purer steel as materials to improve the reliability of bearings under high loads. Taking the application of wheel hub bearings in mining trucks as an example, the bearing capacity is very high. Taking a load capacity of 200 tons as an example, after the vehicle is fully loaded, the force on the single side rear wheel hub bearing reaches about 120 tons. Therefore, if standard materials are chosen for bearings, their dimensions will be very large. In order to minimize the size of the wheel hub and make the design more compact, bearings made of high-purity precision materials are often used at this location. Even so, the inner diameter of the bearing is about 500mm.

The safe and efficient operation of mining machinery and equipment is an important link in the production of mining enterprises. Bearings are one of the important components of mining machinery. The bearings used in large mining machinery are used in harsh environments, and equipment often operates continuously for 24 hours. The special engineering and mining of mining machinery have put forward more stringent requirements for bearings. The issue of mining production safety is also a hot topic of concern for the government and the people. Therefore, it can be seen that bearings are very important for the safety production of mining enterprises.

LTZC Bearings mainly used in mining industry

• Three Row Cylindrical Roller Slewing Bearing

The Triple-row Roller Slewing Bearing has three seating rings, which separate the upper, lower and radial raceways. It can specify the loads of each row of rollers. Moreover, its load carrying capacity and it can bear different loads simultaneously.

• Double Row Ball Slewing Bearings

Double-row ball slewing ring with same diameter balls is usually used for wind driven generators and concrete pump trucks. In wind driven generator applications, double-row ball slewing ring is often installed at the bottom of propellers for variable pitch control which requires zero clearance, large start friction moment and high running accuracy.

• Four Point Contact Ball Slewing Bearing

Four-point contact ball bearing is comprised of an outer ring and an inner ring in integral structure or split structure. The two split rings of bearings in split structure are bolted together before delivery. Usually cages or spacers can be found in four-point contact ball bearings. In addition, bearings in full-filled ball structure is used only for large loads, thereby the full-filled ball structure bearings features good loading capacity and larger friction, the latter may result in scratches on the contact balls.

• Cross Cylindrical Roller Slewing Bearing

  The Single-row Crossed Roller Slewing Bearing consists of two seating rings. It has compact structure, light weight, and high manufacturing accuracy. Due to the small assembly clearances, it has high requirements for the assembly accuracy. The rollers are 1:1 cross arranged. It can bear the axial force, the overturning moment and a relatively large radial force simultaneously.
  

• Slewing Gear Ring

Slewing Gear Ring are large special structural bearings that can simultaneously withstand large axial loads, radial loads, and overturning moments. Usually, it comes with installation holes, lubricating oil holes, and sealing devices, which can meet the different needs of various hosts under different working conditions.

• Slewing Drive

  Slewing Drive is a full cycle rotary reduction transmission mechanism that integrates a driving power source. It uses a rotary bearing as the driving follower and mechanism attachment. By attaching an active component, driving source, and cover to one of the inner and outer rings of the rotary bearing, the other ring is used as both the driving follower and the connecting base of the driven working component.
