Описание

Self-aligning ball bearings with an extended inner ring are a type of rolling bearing designed to accommodate angular misalignment between the shaft and housing while maintaining smooth operation. 

Design in two rows of balls running on a common spherical raceway in the outer ring; Pivoting inner ring that can compensate for misalignments and shaft deflections; Extended inner ring for easy installation and axial fixation using a tenon screw

QIBR - 11212 TN9 Self-aligning Ball Bearings Characteristics

11212 TN9 Self-aligning Ball Bearings, long life, easy installation and maintenance, economical. 11212 TN9 Self-aligning Ball Bearings, can bear radial load and axial load at the same time, suitable for mechanical equipment with high life requirements.

11212 TN9 Self-aligning Ball Bearing Features and Advantages

Accommodates 3-Degree Misalignment: Compensates for up to 3 degrees of static and dynamic misalignment.

Light Load Performance: Performs well under light loads with low load requirements.

Low Noise: The loose fit between the rolling elements and the outer ring generates low noise levels, making it especially suitable for household items like fans.

Extended Service Life: Exhibits high-speed performance with reduced heat and friction, prolonging its service life and minimizing maintenance.

Application: Widely used in industrial fans, industrial machinery, material handling, food and beverage, automotive components, pulp and paper industries, agricultural equipment, and mining machinery.

QIBR - 11212 TN9 Self-aligning Ball Bearing Optimization

Radial Clearance:Can be supplied with CN or C3 group clearance, or customized clearance based on customer requirements.

Grease Replacement: Select lubrication based on bearing operating conditions, such as SKF LGEV 2 or Fuchs MOLY HD 0.

Cage Material: Select lubrication according to bearing working requirements, such as SKF LGMT 2, Timken GR217, or Shell Gadus S2 V220AC.

Further Customization: QIBR can design and optimize bearings according to customer drawings and operating conditions.

QIBR - 11212 TN9 Self-aligning Ball Bearing Quality Control

Dimension measurement: Multiple high-precision instruments are used to measure various dimensions of the bearing, with an accuracy of up to 0.001mm.

Rotation accuracy: A dial gauge measures minor surface flaws or deviations, with measurement accuracy reaching 0.001mm.

Hardness measurement: The surface hardness of the bearing is measured using a hardness tester, with an accuracy of ±0.5HRC.

Metallographic analysis: The internal metallographic structure is analyzed using a professional metallographic microscope.

Geometric tolerance: A contour gauge measures the bearing's geometric shape and relative position.

Noise monitoring: A vibration meter monitors the vibration during operation to obtain noise data.

Raw material control: Steel and parts are sourced from ISO 14001-certified suppliers, ensuring product stability while promoting sustainable development.
