SNW 18 X 3 3/16" Split Pillow Block Housing | SKF Compatible Heavy Duty Industrial Plummer Block
The SNW 18 X 3 3/16" Split Pillow Block Housing (Plummer Block) is engineered for exceptional reliability in heavy industrial applications requiring robust support for high-capacity spherical roller bearings. This specific housing is dimensioned for a 3 3/16 inch (80.96 mm) shaft and is typically utilized with a 22218 K or 23218 K bearing mounted via an H 318 adapter sleeve. Manufactured from high-strength cast iron (or optionally, ductile iron for extreme shock loads), the SNW 18 design ensures maximum rigidity, excellent heat dissipation, and superior operational stability, making it the standard choice for mining equipment, aggregate crushers, and large conveyor systems where durability cannot be compromised.
Featuring a split design, this housing significantly simplifies both mounting and maintenance procedures, allowing for easy bearing inspection or replacement without fully disassembling the shaft. The housing base and cap are precisely matched and marked, ensuring proper alignment during installation. The design includes provision for standard grease lubrication through integrated fittings and is compatible with various sealing solutions (such as felt seals, labyrinth seals, or specialized heavy-duty Taconite seals) to protect the internal bearing assembly from abrasive contaminants and moisture, thus extending service life and reducing costly downtime in harsh operating environments.
