How to read LINK-BELT 22311LBC3

223Series
Spherical roller bearings, 223 series. For the same bore, each series has a different outside diameter and width.
11Bore
55 mm bore: 11 × 5.
LBC3Suffix
LINK-BELT suffix: it defines the variant (sealing, cage, internal clearance or other features).

22311 is the standard (ISO) basic designation: it defines the type, the series and the bore.

Description

The Link-Belt spherical roller bearing is a double-row oscillating component designed to withstand high radial loads and angular misalignment between shaft and housing. Its spherical outer raceway allows the assembly to self-align, absorbing shaft deflection and mounting errors. It is used in equipment with long shafts, belt or chain drives, and machinery subject to vibration. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, in industrial bearings.

The series designation is read from its basic number: the first two digits indicate the bearing type and the following digits the size. The suffix LB identifies the Link-Belt execution, and the final C3 indicates an internal radial clearance greater than standard, useful when the fit or the working temperature closes the clearance. Examples such as 22209LBC3, 22210LBC3 or 22216LBC3 show that structure: series number, brand suffix and clearance class. Other series, such as the 22300, are wider and have a higher load capacity.

These bearings are used in belt conveyors, vibrating screens, mills, mixers, centrifugal pumps and industrial fans. In Argentina they are common in food, cement, mining and aggregate processing plants, where shafts undergo deflection and misalignment. They also appear in gearboxes and road machinery. Their self-aligning capability reduces wear and extends service life in the face of imperfect mounting or structural settling.

To select correctly, take into account the radial and axial load, the rotation speed and the shaft diameter. C3 clearance is recommended when the fit is tight or there are thermal gradients. Sealing can be open, with shields or with seals, depending on the environment: in the presence of dust or moisture, choose sealed variants. Lubrication with high-viscosity grease and initial alignment of the housing are key to avoiding premature failures. Mount with suitable tools and check the clearance after fitting.

As for equivalences, Link-Belt spherical roller bearings can be interchanged with other brands that follow the same dimensional and clearance designation. Link-Belt series share dimensions with equivalent series from other manufacturers, but always verify the clearance suffix and the sealing type before replacing. MR Accesorios Industriales advises you to find the compatible alternative for your application.

If you need a Link-Belt spherical roller bearing, write to us on WhatsApp with the full part number or the shaft and housing dimensions. At MR Accesorios Industriales we will quote you promptly and tell you the option that best suits your equipment. We can also manufacture split plummer block housings to measure if your mounting requires it.

Frequently Asked Questions

What are the dimensions of the LINK-BELT 22311LBC3 bearing?
The LINK-BELT 22311LBC3 bearing has a 55 mm bore, a 120 mm outside diameter and a 43 mm width (55 x 120 x 43 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 22311.
What does the C3 suffix mean on a Link-Belt bearing?
The C3 suffix indicates an internal radial clearance greater than standard. It is used when the shaft or housing fit is tight, or when the working temperature may close the clearance. This prevents the bearing from running preloaded and failing prematurely.
How do I know if a spherical roller bearing is compatible with my machine?
You need to verify the shaft diameter, the outer diameter and the bearing width. Also the sealing type and the radial clearance. With that data, at MR we will tell you the equivalence with other brands or the corresponding Link-Belt option.
What lubrication is suitable for a spherical roller bearing?
High-viscosity grease with extreme pressure additives is recommended, suitable for the working temperature and speed. The amount and frequency depend on the environment and the sealing type. In applications with dust or moisture, it is best to choose sealed variants and lifetime lubrication.
