What is the bearing series?
The basic code consists of the bearing series, which indicates the type of bearing, and the bore number, which specifies the bore diameter. The bearing series can be made up of letters and/or numbers that designate the construction, diameter series, and in many cases the width series.
What does NS mean in bearings?
Part number system
|ONE SHIELD AND ONE SYNTHETIC CONTACT SEAL
|NO HOLE IN BAND ON ONE SIDE OF BEARING
|ONE SYNTHETIC CONTACT SEAL (1600-3000 SERIES)
What does 608 mean for bearings?
The standard inline skates bearings have the designation “608”. The “608” means that the bearings are from the 600 series, with a 8mm inner diameter (the width of the hole, i.e., internal bore).
What is the basic concept of bearings?
A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The simplest form of bearing, the plain bearing, consists of a shaft rotating in a hole. Lubrication is used to reduce friction.
What does J mean on a bearing?
“J” Type: Two piece ribbon consisting of two halves that are assembled one half from one side, and the other half from the opposite side. Fold down tabs secure the two halves. This type of cage is guided by the balls. “Loose” clinch type provides lower torque. Material is type 302 stainless steel.
Is ABEC 7 bearings good?
Specifically, thanks to its smaller runout and axial play, an ABEC 7 bearing will perform better and last longer in high speed applications, than an ABEC 3 rated bearing. So, if you need a super precise, long-lasting bearing, ABEC 7 is probably the bearing for you.
What is the main function of bearing?
Nowadays, bearings are one of the most commonly used machine parts because their rolling motion make almost all movements easier and they help reduce friction. Bearings have two key functions: They transfer motion, i.e. they support and guide components which turn relative to one another. They transmit forces.
