The SYWK AYTA from SKF is a cast iron housing paired with an insert bearing that locks to the shaft with set screws. It mounts rotating shafts to fixed structures in power transmission and conveying equipment. MR Industrial Accessories supplies this SKF line and provides technical guidance to match the right variant to your shaft diameter and load conditions.
Reading the code helps when you need a replacement. SYWK refers to the housing with insert bearing, while AYTA describes the set screw locking method and the bearing series. The number between the two letter groups, as in SYWK 1.1/4 AYTA, gives the shaft diameter in inches. Here, 1.1/4" equals 31.75 mm. Other sizes follow the same pattern: the middle value is the shaft diameter, and the suffixes define the insert's characteristics.
These units are common in food processing, packaging lines, belt conveyors, construction equipment, agricultural machinery and ventilation systems. The design allows quick, secure mounting to steel or concrete structures. As self-aligning units, they accommodate minor misalignment and reduce maintenance effort where access is limited.
When selecting a housing, consider shaft diameter, load type (radial, axial or combined) and environmental conditions. Set screw locking suits moderate loads and medium speeds; for heavier loads or higher speeds, review other locking options. The insert's seal protects against dust and moisture, so confirm the correct lubricant and proper alignment between housings to avoid added stress.
For equivalences, insert bearing housings from different brands can often be interchanged when key dimensions match: shaft diameter, distance between mounting holes, height to center and locking type. Always check tolerances and sealing, as these can differ between manufacturers. To replace an existing housing, compare the actual dimensions of the part and consult a specialist.

Frequently asked questions
- What does the number in SYWK 1.1/4 AYTA mean?
- The number indicates the shaft diameter in inches. In SYWK 1.1/4 AYTA, the shaft is 1.1/4" (31.75 mm). SYWK identifies the housing and AYTA the insert's locking type. For other sizes, provide the exact shaft diameter.
- Can this housing handle axial loads?
- Insert bearing housings are primarily for radial loads. For significant axial loads, evaluate other configurations or consult our technical team. Set screw locking may not be sufficient for high axial thrust.
- How do I check if a housing from another brand is equivalent?
- Compare shaft diameter, distance between mounting holes, height to center and locking type. If they match, it is likely interchangeable. Still verify sealing and lubrication. Send us the dimensions or part number and we will advise.
