How to read SKF 6215-2RS1/HC5C3WT
- 62Series
- Deep groove ball bearings, 62 series. For the same bore, each series has a different outside diameter and width.
- 15Bore
- 75 mm bore: 15 × 5.
- 2RS1/HC5C3WTSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
6215 is the standard (ISO) basic designation: it defines the type, the series and the bore.

SKF deep groove ball bearings of series 62 and 63 are medium and heavy section components that support radial and axial loads in both directions. Their compact and versatile design makes them suitable for electric motors, pumps, fans and gearboxes. In this article we explain how to read their designation, in which applications they perform best and what to consider when mounting them. MR Accesorios Industriales sells this line.
The designation of these bearings combines the series number with suffixes that indicate special features. For example, in 6210-2RS1/HC5C3WT, the 62 corresponds to the medium section series, the 10 to the bore diameter, 2RS1 indicates rubber sealing on both sides, HC5 indicates hybrid components with ceramic balls, C3 a radial clearance greater than normal and WT a variant with heat treatment for high temperatures. The examples 6211-2RS1/HC5C3WT and 6313-2RS1/HC5C3WT follow the same logic: series 63 has a higher load capacity than 62.
These bearings are used in industries such as food, chemical, petrochemical and power generation. Equipment such as low and medium voltage electric motors, centrifugal pumps, screw compressors, industrial fans and conveyor belts find in this execution a reliable solution when there are high temperatures or risk of contamination. The combination of sealing and ceramic balls reduces maintenance in demanding environments.
To select the right bearing, take into account the radial and axial load, the rotation speed and the working temperature. The 2RS1 sealing protects against dust and moisture, but limits the maximum speed; if the environment is clean and higher speed is required, an open or shielded variant may be preferable. The C3 clearance is useful when there is thermal expansion of the shaft or housing. Factory lubrication is for life in most cases, but in severe applications it may require relubrication.
When mounting, ensure alignment between shaft and housing to avoid additional loads. Use suitable mounting tools, such as pullers and presses, and avoid hitting the rings. Check the fit and cleanliness of the surfaces. If you replace a bearing, compare the dimensions and tolerances with the original. Equivalences between brands are possible, but always verify that the part number and specifications match.

Frequently Asked Questions
- What are the dimensions of the SKF 6215-2RS1/HC5C3WT bearing?
- The SKF 6215-2RS1/HC5C3WT bearing has a 75 mm bore, a 130 mm outside diameter and a 25 mm width (75 x 130 x 25 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 6215.
- What does the HC5 suffix mean in an SKF bearing?
- HC5 indicates that the bearing incorporates ceramic balls (hybrid), which reduces weight, improves corrosion resistance and allows operation at higher speeds or temperatures than a conventional steel bearing.
- When is a C3 radial clearance advisable?
- C3 clearance is recommended when there are thermal differences between the shaft and the housing, or when interference is expected that reduces internal clearance. Also in applications where greater tolerance to expansion is required.
- Do bearings with 2RS1 sealing need additional lubrication?
- In general, 2RS1 sealed bearings come lubricated for life and do not require maintenance. However, under extreme temperature or speed conditions, it may be necessary to choose variants with shields or open to relubricate.
