FAG BAX series super precision bearings are components designed for very high accuracy and rigidity requirements, where runout and thermal behavior define the quality of the assembly. They are used in machine tool spindles, rotary tables and measuring heads, among other critical applications. MR Accesorios Industriales sells this line as an official brand and helps you identify the correct variant from the complete part number.

The designation is read in blocks. BAX identifies the super precision series; the number that follows is the size, as in BAX50, BAX60 or BAX80. Then come the suffixes: F and T describe the design and the cage or execution type, P4S indicates the precision class, and DBL defines the bearing arrangement in the assembly. That is why two codes that look alike can differ in mounting: the examples BAX55-F-T-P4S-DBL and BAX70-F-T-P4S-DBL show how only the size changes within the same execution.

In Argentine industry these bearings appear in milling machine, grinding machine and machining center spindles, in rotary tables of numerically controlled machines and in metrology equipment where repeatability is decisive. They are also found in high-speed grinding heads and in mountings that combine axial and radial load with rigidity requirements. They are common in auto parts, metalworking, die and capital goods plants, where a spindle failure stoppage is costly.

To select correctly you must define the arrangement: the paired suffixes indicate how the bearings are combined and what loads each one takes. The P4S precision class is chosen according to the runout accuracy the spindle requires, not out of habit. During mounting, take care with housing and shaft alignment, axial clearance and lubrication: oil or grease depending on the speed, in the right amount so as not to raise the temperature. A poorly chosen seal or protection ruins precision before the bearing itself does.

Equivalences between manufacturers are handled by dimensions and precision class, not by the commercial code: a bearing from another brand may share dimensions and accuracy level, but the arrangement, cage and clearance change. That is why it is best to compare drawing against drawing and verify the complete mounting before replacing. If the original code is not available, the alternative is defined by the dimensions and the application, not by a generic table.

If you have the bearing code, the spindle drawing or a photo of the nameplate, send it by WhatsApp to MR Accesorios Industriales. With that data we identify the BAX series variant you need and send you the quote shortly.
