80*125*22mm 7216 AC Angular Contact Bearings GCR15 P4 Precision Red Brown
Angular Contact Bearing 7216 AC P4 Product description:
Angular contact ball bearing series, the main type suffix C (contact Angle is 15 °), AC (contact Angle 25 °) and B (40 °) contact Angle, the bigger the contact Angle, the greater the axial force of the bearing.
Angular contact ball bearings generally use bakelite retainer (model without the suffix/color is red brown) and the nylon cage (suffix TN/color is black), part of the use of fiber reinforced plastic (TA/TB) or glass fiber reinforced nylon (TN9).
This model is PBQ brand high speed precision angular contact ball bearing with a precision level of P5 and P4. Please refer to customer service for the precision P2 bearing.

Description of bearing accuracy.
Bearing precision refers to the dimension precision and rotation precision of the bearing, while the main difference between high precision and low precision is:
The size deviation of the product with high accuracy grade (inner diameter, outer diameter, ellipse, etc.) is smaller than that of the product with low accuracy grade.
Rotation accuracy requirements are different, the product with high precision grade the rotation accuracy (radial runout, outer diameter to beat, end face a race to beat, etc.) are lower than the accuracy grade of the value of the product requirements should be strictly;
Surface shape and surface quality is not the same as the required value, high precision grade of the surface shape and surface quality (race or surface roughness of the channel, circular deviation, furrowed deviation, etc.) are lower than the accuracy grade of the value of the product requirements should be strictly;
The product with high accuracy grade is superior to the product of general precision grade.
The accuracy grade of the domestic brand bearing is based on the international ISO standard, and the accuracy level is from the P0 level of the common level to P6, P5, P4 and P2. For general purpose P0 stage had enough, and high precision bearing used for high-speed rotation, small friction friction/change, beating and placed high precision machine tool in mechanical or precise instrument.
Description of paired bearings.
Angular contact ball bearings in need under high axial load or two-way axial load when the need to use double row or more matching bearing, commonly used way of pairing with back to back (suffix DB), face-to-face (DF), and the same series (DT).
Note though is the single bearing (with no matching suffix) and paired bearings is the same as in the specification, but the matching parameters such as the width of the bearing outer ring, is has more stringent requirements, and a single bearing just meets the requirements of a single bearing. Therefore, the general single bearing will not be used in combination with the paired bearing. Instead, it USES the universal mating type bearing (suffix DU) to mix and match with the paired bearing.
