SNH Series Bearing Housings Manufacturer

JAYCO Engineering India is a leading manufacturer and supplier of high-performance SNH Series Bearing Housings in India. Designed as an advanced upgrade over conventional SN and SNA Series Plummer Blocks, the SNH Series delivers superior strength, improved sealing performance, and enhanced operational reliability for medium to heavy-duty industrial applications. While maintaining identical mounting dimensions, centre height, and interchangeability with SN and SNA Series housings, the JAYCO SNH Series incorporates structural enhancements to withstand harsh operating environments, high vibration, contamination, and heavy industrial loads. These heavy-duty bearing housings are ideal for cement plants, mining industries, steel mills, conveyors, crushers, power plants, and other demanding industrial applications.

JAYCO SNH Series Bearing Housings are engineered with reinforced structural components to improve rigidity, lubrication flow, and long service life.

Key Design Highlights:

  • Strengthened bottom cavity with thicker wall section
  • Central cross rib for enhanced rigidity and load distribution
  • Additional reinforcing rib on the housing cap
  • Flat internal cavity design for improved lubricant circulation
  • Horizontally split housing for easy bearing mounting and maintenance
  • Optimized design for medium and heavy load industrial applications

These features ensure reliable performance under severe working conditions and extended bearing life.

Bearing Size Range & Configuration

The SNH Series accommodates both tapered bore bearings with adapter sleeves and cylindrical bore bearings.

Tapered Bore Bearings with Adapter Sleeves:

  • Shaft diameter range: 20 mm to 140 mm

Cylindrical Bore Bearings:

  • Shaft diameter range: 25 mm to 160 mm

These configurations allow flexible bearing arrangements for different industrial operating requirements.

Axial Location & Lubrication System

JAYCO SNH Series Bearing Housings are designed for efficient lubrication and precise axial positioning.

Lubrication Features:
