The SKF YAT series is a Y-bearing insert that combines a spherical outer ring with two set screws on the inner ring. It is designed for equipment running at low to medium speeds under moderate loads, where mounting and removal must be done without specialized tooling. Typical applications include conveyors, fans and agricultural machinery. MR Industrial Accessories LLC supplies this line and can help you confirm the correct size for your shaft and housing.
The YAT designation refers to a series 2 Y-bearing. The number that follows the letters gives the bore diameter: YAT 203 is 17 mm, YAT 204 is 20 mm, YAT 205 is 25 mm and YAT 206 is 30 mm. When a hyphenated suffix appears, as in YAT 203-008 or YAT 205-100, it points to a special or inch size; the numeric suffix is tied to a diameter in inches or to a width variant. Reading the full code is the only reliable way to avoid a size mix-up.
These inserts are found in belt conveyors, bucket elevators, fans, mixers and farm equipment. Food plants, cement operations and metalworking shops use them regularly. The spherical outer ring absorbs small misalignments when the bearing sits in a split plummer block housing or a take-up frame. Because the inner ring is secured with set screws, assembly on unmachined shafts is straightforward, which keeps field maintenance moving.
Selection starts with the shaft diameter and the housing type. The standard seal is a double-lip design with metal protection; for dusty or wet conditions, look at variants with heavier seals. Bearings arrive pre-lubricated with lithium grease, though humid environments may call for periodic relubrication. During mounting, align the housing and tighten the set screws with a torque wrench to the recommended torque so the inner ring is not deformed.
Equivalent Y-bearings from other makers carry their own codes, such as UC, GYE or YAR. Codes do not translate exactly from one brand to another, since tolerances, seals and fixing methods can differ. When replacing a Y-bearing, compare bore diameter, outer diameter, width and fixing type. MR Industrial Accessories LLC can help you match the right reference.
To request a quote, send the complete bearing code, for example YAT 205-014, along with the quantity. If the code is not available, provide the shaft and housing dimensions instead. The team replies via WhatsApp or email and can suggest equivalents and help you choose.

Frequently asked questions
- What does the -008 suffix mean in YAT 203-008?
- The -008 suffix denotes a size variant, generally an inch bore or a special dimension. In this case it corresponds to a 1/2 inch bore. Always check the complete designation to confirm compatibility with your shaft.
- Can this bearing be used at high speeds?
- It is not the best choice for that. Y-bearings with set screws are intended for low or medium speeds, since the fixing system can lose adjustment at high revolutions. For higher speeds, consider bearing types with more precise fits.
- How are YAT bearings lubricated?
- They are supplied factory-lubricated with grease. In demanding environments they can be relubricated through the lubrication channel if the housing allows it. Use a grease compatible with the original and follow the manufacturer's recommendations to avoid damaging the seals.
