The SKF SY LF/AH is a ready-to-mount pillow block that pairs a cast iron housing with a Y-series insert bearing. It supports rotating shafts in fixed structures, offers self-alignment, and fixes quickly to the shaft. This makes it a practical choice for power transmission where maintenance access is limited.
The code SY … LF/AH breaks down as follows: SY denotes the split pillow block with cast iron base. The number after SY gives the shaft diameter in inches, such as SY 2.3/16 LF/AH or SY 2.7/16 LF/AH. LF and AH are variants for sealing and insert fixing: LF typically means a special seal for dusty or humid conditions, while AH indicates set screw fixing on the inner ring. Always cross-check the diameter against your shaft and the technical data sheet for the specific size.
Typical applications include belt conveyors, bucket elevators, mixers, mills, packaging lines, and process equipment in food, chemical, cement, and aggregate operations. The design lets you mount the shaft without machining the housing and compensates for minor misalignment, which simplifies maintenance on continuous production lines.
When selecting, confirm shaft diameter, load type (radial, axial, or combined), and ambient conditions. The LF seal guards against dust and splashes; for frequent washdowns, consider additional sealing. The AH insert is secured with set screws, so the fit must be firm without distorting the ring. Follow the manufacturer's lubrication schedule and check alignment between pillow block and shaft to avoid parasitic loads.
Y-bearing pillow blocks with insert bearings are interchangeable across brands for main dimensions, but tolerances and fixing systems can differ. An SKF unit may replace another with a similar designation, yet sealing and fixing suffixes affect performance. Do not mix inserts from different brands in the same housing without confirming compatibility. MR Industrial Accessories supplies SKF and can help you find a suitable equivalent.

Frequently asked questions
- What does the LF/AH suffix mean on an SKF SY pillow block?
- LF indicates a reinforced sealing variant for dusty or humid environments. AH refers to fixing the insert to the shaft with set screws. Together they define the protection level and mounting method.
- How do I determine the correct shaft diameter?
- Measure the shaft with a caliper and match it to the number after SY in the designation. For example, SY 2.3/16 fits a 2 inch and 3/16 shaft. If unsure, contact us with the exact measurement.
- Can I replace the insert bearing without changing the housing?
- In most cases, yes. Check that the new insert has the same outer dimensions and fixing system. Provide the housing code and we will confirm compatibility.
