Low Vibration Plummer Block Bearing for Agricultural Machinery SN505 - SN532
Split plummer block housing type:
1. SAF Split pillow block with 2 or 4 attachment bolt holes in the base
2. FSAF Split pillow block with 4 attachment bolt holes in the base when optional
3. SAFD Split pillow block made of ductile iron
(the casting differs from SAF pillow blocks)
4. SAFS Split pillow block made of cast steel
5. SNL Split pillow block
Description:
Pillow block bearing (insert bearing with housing) is rolling bearing together with a bearing unit. Most of the outer spherical bearings are made of spherical and spherical bore with imported bearing mounted together, the structure forms, versatility and interchangeability. Meanwhile, in the design of these bearings also have some-Mind, easy to install, has a dual structure of sealing device that can work in harsh environments. Bearing is generally used cast molding. Common blocks are vertical seat (P), square blocks (F), Boss Square Block (FS), Boss round seat (FC), diamond-shaped seat (FL), annular seat (C), slide seat (T ), etc.

Housing series
| 0(00) | Housing for bearings in the Diameter Series 0 with a tapered bore, (00) is the bearing size code (e.g. SAF 048 KA x 8.15/16 is for a 23048 CCK/W33 bearing) |
| 2(00) | Housing for bearings in the Diameter Series 2 with a cylindrical bore (e.g. SAF 222 is for a 22222 E bearing) |
| 3(00) | Housing for bearings in the Diameter Series 3 with a cylindrical bore (e.g. SAF 326 is for a 22326 CC/W33 bearing) |
| 5(00) | Housing for bearings in the Diameter Series 2 with a tapered bore on an adapter sleeve (e.g. SAF 517 is for a 22217 EK bearing) |
| 6(00) | Housing for bearings in the Diameter Series 3 with a tapered bore on an adapter sleeve (e.g. SAF 626 is for a 22326 CCK/W33 bearing) |
Designed for long bearing service life
SAF housings contribute to long bearing service life:- A proper machined bearing seat provides a suitable fit together with the appropriate bearing.
- Size and grade specific cap bolts offer superior clamping force between the cap and base.
- Effective seals protect the bearing from contamination and keep the lubricant in.
- Lubrication features enable frequent relubrication if necessary.
Designed for demanding applications
SAF housings are designed for heavy-duty operation in conveyors, mining, papermaking equipment as well as lighter duty and high speed service in fans, blowers and other applications:- Flat surfaces on the cap accommodate condition monitoring attachments and other application specific fittings.
- A large choice of seals meet nearly all application requirements.
Designed for easy mounting
SAF housings ease installation:- A flat square foot helps to accurately align the housing.
- Cast-in dimples locate dowel holes or vents during field installation.
- Dowels locate the cap and base for correct assembly.
- Pry slots make it easy to remove the cap for bearing installation and maintenance.
- Housing sizes from 507 to 528 and 211 to 228 offer further helpful features like cast in grease fill lines inside the base and cast in centreline marks on the base for easy alignment.
