NSK Taperer Roller Bearings - Capable of taking high radial loads and axial loads in a single direction, also available in two and four row versions to support axial loads in either direction.
NSK Maintenance Tools AIP+ : NSK’s laser alignment solution LAB-Set contains two line laser transmitters, making alignment far more accurate than single laser head types.
Services - Troubleshooting - Damage by Type - Scoring is surface damage due to accumulated small seizures caused by sliding under improper lubrication or severe operating conditions. Linear damage appears circumferentially on the raceway and roller surfaces.
Services - Troubleshooting - Damage by Type: Fracture refers to small pieces which were broken off due to excessive load or shock load acting locally on a roller corner or rib of a raceway ring.
Services - Troubleshooting - Damage by Type - Denting: When debris such as small metallic particles are caught in the rolling contact zone, Denting occurs on the raceway surface or rolling element surface.
Services - Troubleshooting - Damage by Type - Smearing is surface damage which occurs from a collection of small seizures between bearing components caused by oil film rupture and/or sliding. Surface roughening occurs along with melting.
Services - Troubleshooting - Damage by Type: Wear is surface deterioration due to sliding friction at the surface of the raceway, rolling elements, roller end faces, rib face, cage pockets, etc.
Services - Troubleshooting - Damage by Type - Cage damage includes: Cage deformation, fracture and wear; Fracture of cage pillars; Deformation of side face; Wear of pocket surface; and Wear of guide surface.
Troubleshooting - Damage by Type - Flaking occurs when small pieces of bearing material are split off from the smooth surface of the raceway or rolling elements due to rolling fatigue, thereby creating regions having rough and coarse texture.
Troubleshooting - Damage by Type: If all conditions are known both before and after the failure, including the application and operating conditions, then a countermeasure can be determined by studying the nature of the failure and its probable causes.
Services - Troubleshooting - Damage by Type - Peeling: Dull or cloudy spots appear on surface along with light Wear. From such dull spots, tiny Cracks are generated downward to a depth of 5–10 µm. Small particles fall off and minor Flaking occurs widely.
Services - Troubleshooting - Damage by Type - Pitting: The pitted surface has a dull luster which appears on the rolling element surface or raceway surface.
Services - Troubleshooting - Damage by Type: Cracks in the raceway ring and rolling elements. Continued use under this condition leads to larger Cracks or Fractures.
Services - Troubleshooting - Damage by Type - False Brinelling: Among the different types of Fretting, false brinelling is the occurrence of hollow spots that resemble brinell dents and are due to Wear caused by vibration and swaying.
