The SKF SYFJ TF is a ready-to-mount Y-bearing unit that pairs a cast iron housing with an insert ball bearing. It supports rotating shafts in equipment where installation is straightforward and upkeep is minimal. MR Industrial Accessories LLC supplies this SKF line and can help you match the unit to your application.
Reading the code helps when ordering. SYFJ denotes a cast iron housing for a Y-bearing with an insert bearing, secured by screws. TF covers the seal design and insert characteristics. The number in the middle, as in SYFJ 20 TF, SYFJ 30 TF or SYFJ 45 TF, gives the shaft diameter the unit fits. Every size follows the same layout, with housing and insert dimensions changing accordingly.
Typical installations include belt conveyors, bucket elevators, mixers, mills and process lines in food, chemical, cement and aggregate operations. These units suit shafts with normal tolerances: the shaft slides into the insert and the housing bolts to the frame. The TF seal handles dust and moderate moisture; for frequent washdowns or heavy contamination, add extra sealing.
When selecting a unit, confirm the shaft diameter, the radial and axial loads, and the operating environment. The insert bearing is generally pre-lubricated. During mounting, align the housing with the shaft and tighten the insert's set screws to the specified torque. Checking alignment and re-lubricating at intervals helps the unit last.
Interchange requires more than a matching shaft size. Y-bearing units from different makers can vary in bolt hole spacing, center height, locking method and seal type. To replace an existing unit safely, begin with the full part number and check the critical dimensions against the drawing or the original part.
MR Industrial Accessories LLC supplies the SKF Y-bearing unit line. Send part numbers such as SYFJ 20 TF, SYFJ 30 TF or SYFJ 45 TF by WhatsApp or email, along with a photo of the mounting if possible, and the team will confirm the correct variant and provide a quote.

Frequently asked questions
- What does SYFJ TF mean on an SKF housing?
- SYFJ identifies a cast iron Y-bearing housing with an insert bearing and screw fixing. TF refers to the sealing type and insert features. The middle number, such as 20 in SYFJ 20 TF, indicates the shaft diameter. This is SKF's nomenclature for this product family.
- How do I choose the right size for my shaft?
- Measure the shaft diameter where the insert bearing mounts and compare it with the series options. Also check the housing's bolt hole spacing and center height to match your structure. If unsure, send the measurements by WhatsApp and we will advise.
- Can it be replaced with another brand?
- Yes, but a matching shaft diameter is not sufficient. Different brands vary in mounting dimensions, fixing system and sealing. Compare bolt hole spacing, center height and insert shape. For a safe replacement, start from the original part number and verify the critical dimensions.
