1206 is a double row self-aligning ball bearing (Class 1 bearing). Its core advantages are self-aligning, low friction, and suitability for light loads and high speeds, making it suitable for scenarios where shaft misalignment is prone to occur.

I. Core Parameters (Standard Cylindrical Hole 1206)

II. Structure and Advantages

Self-aligning: The outer ring spherical raceway compensates for angular misalignment (≤2.5°) caused by shaft bending and installation errors, avoiding edge stress concentration.

Low friction, low heat generation: Smooth rolling of double-row steel balls, suitable for high-speed, light-load conditions.

Load characteristics: Primarily radial loads, capable of withstanding slight bidirectional axial loads.

Maintenance-friendly: Low wear, long service life, easy installation/disassembly (a locknut can be used for the 1206K tapered bore).

Quiet operation and low vibration: Smooth rolling, suitable for noise-sensitive equipment.

III. Typical Applications

Motors/Pumps: Small motors, fans, water pumps, compressors.

Transmission and Conveying: Gearboxes, textile machinery, mesh belt furnaces, conveyor equipment.

Light Industry/Instruments: Medical devices, plastic machinery, printing/binding equipment, instrument shafts.

General Machinery: Machine tool accessories, cleaning equipment, dryers, small transmission mechanisms.

IV. Common Suffix Meanings

1206K: Tapered hole (1:12), facilitating adapter sleeve installation.

1206-2RS: Double-sided rubber seal, dustproof and waterproof.

1206/C3: Radial clearance greater than the standard group, suitable for high-speed/temperature-rise scenarios.
