SKF SNL 516-613 Split Plummer Block Housing

The SKF SNL 516-613 is a split plummer block housing from SKF's SNL series, designed to accept shaft diameters of 75–85 mm and accommodate a wide range of spherical roller bearings, including the SKF 22316, 23116, and related series, making it a versatile bearing housing solution for general industrial shaft support across Saudi industrial installations. The split design — a seating on the base and a cap bolted over the bearing — allows the bearing and shaft to be installed and removed without disturbing the shaft end connections, a significant advantage in long shaft arrangements common in Saudi industrial fan and ventilation equipment, conveyor systems, and pump installations where multi-bearing shafts are the norm.

The SNL 516-613 is manufactured from grey cast iron (GCI) to tight dimensional tolerances, providing a rigid, vibration-damping housing that contributes to bearing life by maintaining accurate bore geometry under load. SKF designed the SNL series with generous labyrinth seal grooves to accept SKF's standard TSN or TSNG seal rings — a critical feature for Saudi Arabian industrial environments where airborne dust, sand, and process contamination represent the primary cause of premature bearing failure in exposed shaft positions. The housing's oil bath and grease lubrication capabilities support both grease-packed operation for low-maintenance applications and flooded oil operation for high-speed or high-temperature service.

In Saudi Arabia, the SKF SNL series plummer block is the standard housing specification for industrial fan and ventilation equipment manufactured for cement plants, power stations, and process facilities across the Kingdom. ARAMCO's standard for process plant ventilation and cooling fan equipment references SKF SNL housings as the preferred bearing housing for fan shaft support, and Saudi cement plant engineers routinely specify SNL housings for kiln cooler fan shaft arrangements where dust sealing is paramount. The SNL 516-613's compatibility with a wide range of bearing sizes through the hyphenated sizing system (-613 designates the bearing seat diameter) allows a single housing stock to accommodate bearing selection changes without housing replacement.

Razz Middle East supplies the SKF SNL 516-613 as part of a complete bearing unit, typically paired with a selected spherical roller bearing, adapter sleeve, and sealing rings. Our engineering team provides housing selection and bearing compatibility guidance, and we maintain stock of the commonly specified bearing + housing combinations for prompt delivery to Saudi industrial customers.
