What does NSK stand for bearings?
(日本精工株式会社, Nippon Seikō Kabushiki-gaisha, Japan Precision Company), also known in some markets as NSK Automation, is a large manufacturer of bearings globally and the largest in Japan. The company produces industrial machinery bearings, precision machinery and parts, and automotive bearings and components.
What is cylindrical load?
Cylindrical roller bearings have high radial-load capacity and moderate thrust loads. They contain rollers which are cylindrically-shaped, but are not true cylinders. Instead, these rollers are crowned or end-relieved to reduce stress concentrations.
What is NUP type cylindrical roller bearing?
NUP (RIP, RP) Cylindrical bearing type NUP has a double ribbed outer ring and a single-ribbed inner ring with an abutting loose rib, which allows the bearing to provide axial location and to carry light thrust loads in both directions. Factors governing radial and thrust load capacities are the same for type NJ.
Is NSK a good brand?
NSK is a global bearing company with over 100 years of history. It offers the highest levels of safety and Japanese quality. Genuine NSK bearings are much more cost effective than fake bearings because they last much longer and you don’t have to pay for repairs caused by failures.
Are NSK Bearings good?
What is radial load?
Radial Load is defined as the maximum force that can be applied to the shaft in the radial direction (any direction perpendicular to the motor shaft axis). Radial load is also referred to as the “overhung load” because of how the load may “hang” off the shaft.
What is NJ type bearing?
NJ (RIJ, RJ) Cylindrical bearing type NJ has double-ribbed outer and single-ribbed inner rings and can support heavy radial loads, as well as light unidirectional thrust loads up to 10 percent of the radial load.
Why use cylindrical roller bearings?
Cylindrical bearings resist damage from fatigue, shock and edge loads, and they tolerate misalignment better than rolling element bearings. Ultimately, customers will experience savings from lower maintenance costs and extended equipment life.
How can you tell a fake NSK bearing?
To begin, check the markings. An absence of markings is an obvious sign that the bearings are fake. If markings are present, are they similar to standard manufacturer markings, or are they located on different areas of the bearing to normal? Both can point to illegal manufacture.
How can you tell if NSK Bearings are fake?
What is axial load?
Axial loading is defined as applying a force on a structure directly along an axis of the structure. From: Basic Finite Element Method as Applied to Injury Biomechanics, 2018.
