The SKF QJ 212 is a four-point angular contact ball bearing that handles combined radial and axial loads in both directions. It suits high-precision, rigid arrangements such as machine tool spindles, gearboxes, and transmission equipment. Its four-point contact geometry provides a high tilting moment capacity and substantial axial load support.

Reading the QJ 212 code: QJ identifies a four-point angular contact ball bearing. The digits 212 follow the standard bearing numbering system, where the last two digits give the bore diameter in millimeters: 12 × 5 = 60 mm. Suffixes may appear to indicate design variants such as brass cage, internal clearance, or special heat treatment. For the exact configuration of a specific item, check the corresponding product page.

Typical applications include milling, drilling, and grinding machine spindles, speed reducers, gearboxes, lifting equipment, rotary tables, high-pressure pumps, and compressors. The bearing's ability to take axial loads in both directions makes it a fit for arrangements requiring rigidity and precision.

When selecting a QJ bearing, consider the radial and axial loads, rotation speed, and environmental conditions. Verify internal clearance and sealing: these bearings are usually open, so they need external lubrication and protection from contaminants. Mount with precise alignment using a hydraulic press or induction heater; avoid impacts that can damage the raceways. Grease or oil lubrication is possible depending on the application, and the lubricant must be kept clean and at the correct level.

For interchangeability, SKF QJ series bearings can be replaced by products from other manufacturers that follow the same designation and standardized dimensions. Tolerances and internal clearance can differ between makers, so confirm compatibility before substituting. A specialist can help you assess the options.
