Superbolt thrust collars consist of unthreaded rings with jackbolts which are used primarily on the bearings on large steel mill rolls. Sizes up to 40" inside dia. have been shipped, capable of creating 4,500,000 lbs of bearing preload. Typical inside diameters range from 5" to 30", but virtually any size can be designed and produced.

Significance: Typically thrust collars are implemented in integrally geared compressors to absorb the axial load on the pinion shaft (see Fig. 1). This provides 

The main function of thrust bearing is to transmit the axial load applied to the shaft, prevent the shaft from moving axially and reduce the friction between the moving parts. These types of

thrust collar,* page 28. Occasionally the thrust bearing parts are located in the after end of the gear housing, or sometimes separately, in a specially-built housing on the line shaft. In these latter cases, the shaft size often requires using eight large-bore shoes instead of six standard shoes. Eight-shoe bearings are special, and are

26/07/2022 · A thrust or collar bearing supports the shaft subjected to end or axial thrust. The surfaces of the bearing are generally flat or cylindrical. And they may consist of nonferrous metal surfaces known as bushes or hardened steel races supported by steel balls or rollers. In the above case, the bearing is known as bush bearings, and the latter is

Ball thrust bearings, sometimes referred to as a flat-race thrust bearings, are composed of ball bearings supported in a retainer ring and are held between two thrust washers. Thrust bearings allow smooth rotation under high thrust loads at low and medium speeds.

Thrust bearings are usually classified as fixed geometry or tilting pad. Figure 1 shows a simple flat land fixed geometry bearing. The surfaces 

Thrust collars (TCs) are bearing elements used in geared machinery that transmit axial loads from one shaft to another.

01/08/  · In May 2005, the Unit 1 thrust bearing failed again. A visual inspection showed the babbitt contained fatigue cracking on all the bearings shoes. PUD staff discovered three of the eight bolts between the thrust runner and thrust collar had broken.

Thrust collar is applied as thrust bearing of each pinion shaft. In this system, the thrust force of the compressor is transmitted to the thrust 

Threaded Collars & Bearing Locknuts. Threaded shaft collars have the greatest axially holding power and can be used with shock loads. A popular shaft collar variation is the threaded bore collar. Typically, threaded collars are available in the same styles as smooth bore collars, but are most popular in the one and two piece clamp styles.
