Description
SKF 2306 M/P6 is a self-aligning ball bearing reference, within Bearings. Request a quote for 2306 M/P6 via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.
The SKF self-aligning ball bearing of series 2305 M/P6 is a double-row ball bearing with a spherical outer ring surface, which allows it to self-align and compensate for angular misalignments between shaft and housing. It is used in equipment where perfect alignment is not guaranteed, such as transmissions, pumps and industrial fans. Its robust design and ability to withstand moderate radial and axial loads make it a reliable option in demanding applications.
The designation 2305 M/P6 is interpreted as follows: the prefix 23 corresponds to the series of double-row self-aligning ball bearings; the number 05 indicates the bore diameter (5 × 5 = 25 mm). The suffix M indicates that the cage is machined brass, suitable for high speeds and elevated temperatures. The suffix /P6 indicates precision class 6 according to ISO standard, with tighter tolerances than the normal class. In the example 2306 M/P6, the bore is 30 mm. Knowing these codes allows you to quickly identify the bearing's characteristics.
These bearings are used in a wide variety of industries in Argentina: food plants, cement plants, steel mills, paper mills and petrochemical plants. They are common in industrial fans, centrifugal pumps, compressors, conveyor belts and machine tools. Their self-aligning capability makes them ideal for equipment where shafts may bend or where housings are not perfectly machined. They are also used in applications with combined loads, where the axial component is moderate.
To select a self-aligning ball bearing correctly, take into account the radial and axial load it must withstand, the rotation speed and the environmental conditions. Sealing is key: if there is dust or moisture, choose versions with seals or shields. Lubrication must be adequate: high-quality grease for high temperatures or oil in circulation systems. During mounting, verify initial alignment and avoid striking the outer ring. The brass cage M requires careful handling so as not to deform it.
Regarding equivalents, self-aligning ball bearings are manufactured under international standards, so a similar code from another brand may be interchangeable, but always verify the exact dimensions and tolerances. SKF's series 23 with suffix M and class P6 has equivalents in other brands, although suffixes may vary. Do not assume that a similar code is identical: consult the manufacturer's tables. At MR Accesorios Industriales we sell SKF as an official brand and can advise you on interchangeability.
If you need to replace a self-aligning ball bearing, send us the complete code via WhatsApp to MR Accesorios Industriales. With more than 80 years in the trade, we help you identify the correct part and request a quote. Let's not improvise with measurements: the exact code prevents errors and plant downtime.

Frequently Asked Questions
- What does the suffix M mean on an SKF bearing?
- The suffix M indicates that the cage is machined brass, a material that better withstands high speeds and temperatures than stamped steel cages. It is common in precision bearings.
- What does precision class P6 indicate?
- Class P6 is a precision tolerance according to ISO, tighter than the normal class. It is used in applications where greater rotational accuracy is required, such as machine tool spindles.
- Is this bearing interchangeable with other brands?
- It may be if dimensions and tolerances match, but suffixes vary between manufacturers. Always verify the complete code and consult with us before replacing.
