Decoding SKF N 313 ECP
- N 3Series
- Cylindrical roller bearings, N 3 series. Series differ in outside diameter and width even when the bore is the same.
- 13Bore
- Bore 65 mm (13 × 5).
- ECPSuffix
- SKF suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
N 313 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
SKF N 313 ECP measures 65 mm across the bore and 140 mm across the outside diameter; its width is 33 mm (65 x 140 x 33 mm).

For equipment that must handle substantial radial forces at speed, the SKF N ECP series of cylindrical roller bearings is a common choice. These single-row bearings use cylindrical rollers to provide rigidity and reliable operation in demanding industrial settings. MR Industrial Accessories LLC supplies this SKF line to customers across the United States and Latin America, and our team can help you match the correct size to your application.
Reading the part number helps you specify the right bearing. The N prefix means the outer ring has no flanges, so the ring and shaft can move axially relative to each other. The digits that follow are a size code: the last two indicate the bore in millimeters—03 for 17 mm, 04 for 20 mm, and so on. The ECP suffix points to an optimized internal design with a polyamide cage. In short, the numeric portion tells you the bore diameter.
These bearings appear in conveyor systems, pumps, fans, gearboxes, and machine tools. Their capacity for heavy radial loads and their ability to run at high speeds suit them to mining, cement, food processing, and petrochemical operations. You will also find them in power transmission equipment where stiffness and precision matter.
When selecting a bearing, review the radial load, operating speed, and ambient conditions. Mount it with the proper tools and avoid striking the rollers directly. Grease or oil lubrication both work, depending on the application, but shaft-to-housing alignment must be correct. Sealing choices depend on the environment; add extra protection where contamination is present.
Bearings in similar series from other manufacturers may be dimensionally interchangeable, but always check tolerances and internal design before substituting. SKF products meet international standards. If you are replacing a bearing, compare the critical dimensions and let our technical team confirm compatibility.

Frequently asked questions
- SKF N 313 ECP bearing: what are its dimensions?
- SKF N 313 ECP measures 65 mm across the bore and 140 mm across the outside diameter; its width is 33 mm (65 x 140 x 33 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation N 313.
- What does the ECP suffix indicate on an SKF bearing?
- It denotes an optimized design with a polyamide cage, which contributes to higher load capacity and better heat dissipation.
- How do I select the correct N ECP bearing?
- Consider radial load, speed, shaft diameter, and environmental conditions. The numeric code gives the bore diameter. If you need help, contact us on WhatsApp with your equipment dimensions.
- Can SKF N ECP bearings be replaced with other brands?
- Cylindrical roller bearings of equivalent series from other manufacturers may be dimensionally interchangeable, but verify tolerances and internal design. Consulting a specialist before replacement is recommended.
