10PCS - MR83ZZ Bearing 3x8x3 mm Metal Double Shielded Ball Bearings MR83z ABEC-1

Description

Miniature Bearing Types & Features
Miniature and instrument ball bearings can be divided into two basic types, deep groove and angular contact. The first (deep groove) can also be classified as "Open", "Shielded", or "Sealed" depending on the existence and type of seal or shield. Deep groove ball bearings have two inherent advantages;
they can sustain some axial load in either direction as well as radial loads, and the two raceway cross-sections are simple circular arcs which can be very precisely finished so the bearings have low friction and very little noise or vibration. Several different cage designs are available with different characteristics and the choice depends upon the individual application.

MORE FOR YOU
1. Why do the bearings I receive have shaking?
The clearance of the bearing is related to the play.
The default is the standard C0 clearance
,
which is usually 3-18um.
The corresponding principle is shown in the figure below.
If you don't need to shake
,
please choose C2 small clearance bearing
,
If you have any questions
,
please contact us before purchasing.
2. Do I still need to add grease to the bearings?
Grease does not need to be added extra Because the bearings are pre-filled with grease at the factory.

please operate under the guidance of a professional.
3. What is the accuracy of ABEC-1?
ABEC is the American ANSI standard.
The corresponding German DIN standard and international ISO standard are as follows:
4. Why do stainless steel bearings can be sucked up with magnets?
Standard bearings are made of chrome steel. For special environments
,
stainless steel bearings are used.
Commonly used stainless steel materials are 440C
,
420
,
304
,
316.
Except that 316 is non-magnetic material
,
Other stainless steel materials will have weak magnetic
,
This is determined by the composition properties of the material itself.
Please contact us for specific application guidance.
