The SKF YAR series is a Y-bearing with an extended inner ring and set screws, designed to fit into split or pillow block housings. The …RFGR/HV version adds a double-lip rubber seal and a special heat treatment for elevated temperatures. It suits equipment exposed to heat, dust, or moisture, such as ovens, dryers, and conveyors. MR supplies this SKF line and helps you select the right size.
The code YAR identifies a bearing with an extended inner ring and two set screws for shaft locking. The suffix 2RFGR means a reinforced contact seal with a rubber lip that keeps out dust and splashes. HV signals a heat treatment for high-temperature operation. In codes like YAR 204-2RFGR/HV or YAR 208-108-2RFGR/HV, the numeric part shows the bore size; when a second number appears after the dash, it indicates the bore in inches.
Typical installations include belt conveyors, bucket elevators, rotary dryers, bakery ovens, foundry equipment, and agricultural machinery. In food, ceramic, and cement plants, and in aggregate processing, heat and contamination can shorten the life of standard bearings. The reinforced seal and HV treatment help these inserts hold up under such conditions.
When selecting, verify the shaft diameter and the housing type. The 2RFGR seal is fitted at the factory and should not be removed or altered. For lubrication, choose a grease rated for high temperatures, such as a synthetic or silicone-based product, based on your operating range. During mounting, align the housing, tighten the set screws onto the shaft with the correct wrench, and avoid striking the inner ring. Leave a small axial clearance to allow for thermal expansion.
Y-bearings from different brands can often be interchanged if the basic designation and dimensions match—bore diameter, width, and seal type. However, the HV treatment and 2RFGR seal are specific to this variant. If your equipment runs hot, do not replace it with a standard insert. Always confirm critical dimensions before swapping.
To replace an SKF YAR bearing, send us the full code stamped on the bearing or housing. MR quotes by WhatsApp and helps you confirm the right variant for your application.

Frequently asked questions
- What does the HV suffix mean on a YAR bearing?
- HV indicates a special heat treatment that allows the bearing to work at higher temperatures than a standard Y-bearing. It does not change dimensions or load capacity, only the permissible temperature range.
- Can I replace a YAR 2RFGR/HV with another standard Y-bearing?
- Only if the equipment does not operate at high temperature. The 2RFGR seal and HV treatment are for severe conditions. In a hot environment, a standard bearing may fail prematurely.
- How do I choose the correct Y-bearing size?
- Measure the shaft diameter and the housing bore. The bearing code, such as YAR 204 or YAR 208, indicates the size series. If you have doubts, send a photo of the code via WhatsApp and we will advise you.
