The SEALMASTER SF series 4-bolt flange Y-bearing unit is a mounted assembly that pairs a cast iron housing with a ball insert bearing. It arrives pre-aligned and ready to bolt down, supporting the shaft on a flat surface where four-point fastening is needed.
The SF code breaks down into two parts: the letters denote the 4-bolt flange housing type, while the following number signals the assembly size, increasing from smaller to larger. For example, SF-8, SF-9 and SF-10 share the same construction but differ in insert and housing dimensions. Any suffixes after the number point to sealing, locking or insert variations, so always quote the full part number when requesting a replacement.
Typical installations include material handling systems, belts and elevators, mixers, blowers, centrifugal pumps, industrial washers and process equipment. In food and beverage plants, chemical facilities, tanneries and metallurgical operations, these units are mounted on frames and chassis where the shaft runs perpendicular to the flange. Water treatment equipment and agricultural machinery also rely on them when the environment demands dependable sealing.
Selection starts with shaft diameter, load type and mounting position. The 4-bolt flange spreads the load and permits alignment adjustments before the bolts are tightened. Match the insert sealing to the surroundings: dusty, wet or washdown conditions call for tighter seals. Renew insert lubrication according to the duty cycle, and during installation rest the flange on a clean, flat surface to prevent housing distortion.
When comparing alternatives, mounted housings are matched by construction type, shaft diameter and flange configuration rather than by individual manufacturer part numbers. A 4-bolt flange housing from another brand can serve the same purpose if its mounting dimensions and insert capacity align. To replace an existing unit, send the part number stamped on the housing or the shaft diameter, and we will identify a compatible option.
For any SF series size, from SF-8 to larger assemblies, contact us via WhatsApp or email with the part number or model. The team responds promptly and, when needed, suggests equivalents and helps you choose the right unit.

Frequently asked questions
- What does the SF series indicate in a SEALMASTER housing?
- SF identifies a Y-bearing housing with a 4-bolt flange insert bearing. The number that follows indicates the assembly size, and any suffixes denote sealing or insert locking variants.
- How do I select the correct size for my shaft?
- Begin with the shaft diameter and load type. These determine the insert and housing size. Provide the part number from the old housing or the shaft dimension, and we will recommend the corresponding option.
- Can it be replaced with a housing from another brand?
- Yes, if the construction type, shaft diameter and flange dimensions match. Mounted housings are compared by function and mounting dimensions. Send the part number or model, and we will identify a compatible alternative.
