We are the professional manufacturer of Slewing Bearings and the Big size Ball & Roller bearings. We could manufacture and process varous types Slewing Bearings with the dimensions from 100mm to 6000mm, including Thrust Ball bearings, Thrust Roller Bearings, Four Contact Ball Bearings, Double-row Ball Bearings, Crossed Roller Bearings, as well as the Ball & Roller combinaion bearings Our products have been applied in varous equipments such as Wind Power Generating Apparatus

As SOCARE BEARING one main series, this kind of Slewing bearings are skilfully just as clay in the hand of potter. This kind of Slewing bearing is the most common type, it is made up by two Rings, Balls & Supports, with compact conformation, light weight, the Steel Balls are Four Point Contacting with the arc Raceway, it can bear both Axdial & Radial load and the moment at the same time. It often be used on Stacker Reclaimers,
 

Identification of the Quality of the sound description:Irregular use of hearing to identify the operation is a very common method. For example: With the electronic stethoscope to check does not feel a part of the normal noise often experienced operators to use the method.ntn bearings are well connected to the switch if the state will issue a muffled whining sound. If issued a sharp hissing sound,

Metal sliding ntn bearing material is Higashiura new hardware products, is a composite multi-layer metal bearing materials, bearing materials of the steel liner back to the matrix layer, the bearing structure with a high strength, anti-friction self-lubricating layer of material, from the copper bearing alloy composition, it is not hurting the dual, it can withstand high and low temperature operating conditions.

1: ntn bearing speed decision factors:When ntn bearing load conditions in the 0.1C running, as the rolling element and raceway contact surfaces increases the contact stress to the heart, has led to ntn bearing operating temperature increased, the performance of the lubricant reduces. Therefore, the speed limit imports of bearings will be reduced accordingly. In this case,

Needle roller and cage thrust assemblies are complements of small diameter needle rollers arranged in a spoke-like configuration. Needle rollers are equally spaced by means of a cage whose web section separates the rollers and provides guidance to keep them tracking in an orbital path. The purpose of these assemblies is to transmit a thrust load between two relatively rotating objects while greatly reducing friction.

1. Needle roller bearings are roller bearings with cylindrical rollers which are thin and long in relation to their diameter. They are referred to as needle rollers. In spite of their low cross section the bearings have a high load carrying capacity and are thus extremely suitable for bearing arrangements where radial space is limited 2. Needle roller bearings have a high load carrying capacity in addition to their low cross-section and stiffness

1. Needle roller and cage assemblies consist of a complement of needle rollers held in place by a cage. With no inner or outer ring, the low cross section provides maximum load-carrying capability within the smallest envelope. The mating shaft and housing are normally used as inner and outer raceways. 2. Caged assemblies are roller arrangement with a retainer, placed between two hardened machine elements that act as raceways.
