SONL Series Bearing Housings

Advanced Oil-Lubricated Plummer Blocks by JAYCO Engineering India

JAYCO SONL Series Bearing Housings are horizontally split, oil-lubricated Plummer blocks, developed as an advanced and improved alternative to conventional SOFN/SONL-type housings.

Designed for high-speed, high-load, and continuous industrial operation, JAYCO SONL housings offer excellent lubrication efficiency, easier assembly, superior alignment, and leak-free performance, making them ideal for modern heavy industries.

Why Choose JAYCO SONL Series Bearing Housings?

Engineered for Speed, Load & Long Service Life

JAYCO SONL housings are widely used where:

Oil lubrication is essential

Bearing speed and load are high

Temperature control is critical

Maintenance downtime must be minimized

They are extensively adopted in cement plants, steel mills, power plants, mining, heavy fans, and process industries.

Key Engineering Features of JAYCO SONL Series

✔ Horizontally Split Housing Design

Cap and base are split horizontally and clamped with high-strength bolts

Ensures easy assembly, inspection, and bearing replacement

Dowel pins provided for repeatable and accurate alignment

✔ Very Stiff & Robust Construction

Heavy ribbed structure for maximum rigidity

Maintains alignment under continuous vibration and heavy loads

Faster and more reliable assembly compared to traditional designs

✔ Dimensionally Interchangeable Design

SONL housings are dimensionally interchangeable with SOFN housings

Foundation dimensions and shaft center height maintained

Enables easy retrofit and replacement without base modification

Advanced Oil Lubrication System

✔ Oil Pick-Up Ring Lubrication (Standard)

Oil pick-up ring rotates with the shaft

Lifts oil from sump and supplies it to bearing continuously

Ensures excellent lubrication even at higher speeds

✔ External Circulating Oil Lubrication (Optional)

Provided when bearing speed or load exceeds standard limits

External pump circulates oil through:

Filters

Valves

Heat exchanger

Oil is cleaned, cooled, and re-circulated for optimum bearing temperature control

✔ Deep Oil Reservoir

Large oil sump inside housing

Stores sufficient oil for continuous operation

Improves lubrication reliability compared to splash systems

Superior Sealing Arrangement

✔ Special Labyrinth Sealing Collar

Labyrinth seal design prevents oil leakage

Oil returning through labyrinth is guided back to oil reservoir

Provides excellent sealing against:

Oil loss

Dust ingress

Moisture contamination

Standard Seal:
Labyrinth Seal – TS Type

Bearing Compatibility – SONL Series

JAYCO SONL housings are suitable for self-aligning ball bearings and spherical roller bearings.

Available Dimensional Series

SONL 200/500 – Suitable for bearing series 22200… (Adapter sleeve / Cylindrical bore)

Accessories & Monitoring Provisions

End cover provided for shaft end option

Standard accessories include:

Oil level indicator

Drain plug

Oil inlet plug

Lifting hook / eyebolt

Tappings provided for:
