How to read SKF C 3064 M
- C 30Series
- CARB roller bearings, C 30 series. For the same bore, each series has a different outside diameter and width.
- 64Bore
- 320 mm bore: 64 × 5.
- MSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
C 3064 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF C 3064 M bearing has a 320 mm bore, a 480 mm outside diameter and a 121 mm width (320 x 480 x 121 mm).

The SKF CARB bearing, identified in the C M series, is a self-aligning toroidal roller bearing. Its design compensates for shaft misalignment and flexing, common in equipment with long shafts or separated supports. It is used in applications where the load is high and alignment conditions are not perfect, such as industrial drives, paper machines or mining equipment. MR Accesorios Industriales carries this line as a brand so you can resolve your technical inquiry with support.
The C … M designation reads as follows: the letter C identifies the CARB series, a single-row toroidal roller bearing. The number that follows indicates the size, and the suffix M indicates that the cage is machined brass, suitable for high speeds and loads. For example, C 3164 M combines these characteristics in a specific size. This nomenclature lets you quickly locate the replacement part if you have the complete part number.
These bearings are chosen in industries such as cement, mining, paper and steel, where shafts are subjected to flexing and combined loads. They also appear in gearboxes, continuous process machines and material handling equipment. In Argentina, they are commonly found in production plants that need to reduce downtime due to misalignment. Their self-aligning capability makes them useful when mounting is not perfect.
To select a CARB, take into account the radial and axial load it will bear, the rotation speed and the type of lubrication. The sealing can be open or with shields, depending on the environment. It is key to respect the internal clearance and a correct initial alignment, even though the bearing then compensates for deviations. Lubrication must be suitable for the temperature and contamination of the environment; in dirty environments, it is advisable to opt for seals.
As for equivalents, SKF CARB bearings can be interchanged with similar designs from other brands, but always verify dimensions, tolerances and load capacity. It is not enough for the part number to be similar: you must compare the data sheet. At MR Accesorios Industriales we can guide you if you send us the original part number and the working conditions. Interchangeability is not automatic; it requires verification.

Frequently Asked Questions
- What are the dimensions of the SKF C 3064 M bearing?
- The SKF C 3064 M bearing has a 320 mm bore, a 480 mm outside diameter and a 121 mm width (320 x 480 x 121 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation C 3064.
- What does the M suffix mean in a CARB bearing?
- The M suffix indicates that the bearing has a machined brass cage. This cage is resistant and suitable for applications with high speeds or loads. It does not change the external dimensions, but it does influence performance and heat dissipation.
- How do I know if a CARB replaces another bearing?
- Comparing part numbers is not enough. You must verify dimensions, load capacity, internal clearance and type of sealing. The CARB has its own self-aligning characteristics. Consult us with the original part number and your equipment conditions to evaluate the equivalence.
- Where are CARB bearings used in industry?
- They are used in equipment with long shafts or distant supports, where flexing and misalignment are frequent. They appear in gearboxes, paper machines, cement plants, mining and steel. Their self-aligning capability reduces wear and unplanned downtime.
