45 X 85 X 19mm SKF1209ETN9 1210ETN9 Self Aligning Ball Bearing

Product description:

  

In a self-aligning bearing, the inner ring has two raceways and the outer ring has a single spherical raceway with its center of curvature coincident with the bearing axis. Self-Aligning Double Row Ball Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection. The concave raceway of the outer ring in combination with two rows of balls operate over a wide range of contact angles.
 
 
Features:
 1.Low friction, Long service life, Enhanced operational reliability, Consistency of roller profiles and sizes, Rigid bearing application, Running-in period with reduced temperature peaks, Separable and interchangeable.
2. With a low and smooth coefficient of friction and without stick-slip effects.
3.Suitable for dirty, corrosion, impact load and edge loading.


Application:
large and medium-sized motors,
locomotives,
machine tool spindles,
internal combustion engines,
generators,
gas turbines,
gearboxes,
rolling mills,
vibrating screens,
lifting,
transport machinery.

Regarding on bearings
1) how to prolong service life of bearings?
accurate installation and using, alignment, timely mnitor, re lubrication etc.
2) what is the reason for bearings failure?
it is usually incorrect using method, pollution, improper use of lubricant, damage happened in installation and handing, also including installation error, according to the traces can know the reason why it is failure.
3) how to choose bearings?
analyse mechanical device and use conditions. clear the requirement of bearings. select tupe of bearings, select distribution way of bearings. select dimensions of bearing, select installation method of bearings.
4) when select bearings specifications, what do you need to consider?
the precision of the bearing (rotation precision, dimensional tolerances) internal clearance and preload bearing material and heat treatment. structure of cage and material.
