SBD Series (2200,2300,3000,3100,3200)

Heavy Duty Non-Split Plummer Blocks by JAYCO Engineering

Engineered for High Load Belt Conveyors & Severe Industrial Applications

JAYCO SBD Series Bearing Housings are heavy-duty non-split plummer blocks specially designed for high-load conveyor systems and demanding industrial machinery. Originally developed for heavy belt conveyor drives, these bearing housings are now widely used in mining plants, crushers, sugar mills, wagon tipplers, rotary drums, wind power systems, and bulk material handling equipment. Built with a rigid single-piece construction, JAYCO SBD housings are engineered to withstand extremely high radial and axial loads, severe vibration, shock loading, and continuous-duty industrial operations.

Why Choose JAYCO SBD Series Bearing Housings?

Heavy-Duty Performance for Critical Applications

JAYCO SBD Series Plummer Blocks are ideal for industries requiring:

• High load carrying capacity
• Reliable continuous operation
• Resistance to shock and vibration
• Low maintenance performance
• Long service life in harsh environments

Their reinforced housing structure ensures superior rigidity and operational stability under extreme working conditions.

Key Features of JAYCO SBD Series Plummer Blocks

Non-Split Single-Piece Housing Design

• One-piece non-split construction eliminates joint weakness
• Provides maximum structural strength and rigidity
• Suitable for severe-duty and high-impact applications
• Reduces risk of housing deformation under heavy loads

Dual Cover Arrangement

• Covers provided on both sides of the housing
• High-strength bolting arrangement for secure assembly
• Optional end cover available for closed shaft applications

Reinforced Ribbed Base Construction

• Heavy hollow base with thick reinforced ribs
• Designed for high radial and dynamic load conditions
• Ensures stable performance during heavy industrial operation

High Static & Dynamic Load Capacity

• Designed to handle very high radial and axial loads
• Reliable performance in demanding conveyor and processing systems
• Suitable for heavy-duty industrial machinery

Bearing Compatibility & Shaft Size Range

JAYCO SBD Bearing Housings are suitable for spherical roller bearings and support:

• Adapter sleeve mounted bearings
• Cylindrical bore bearings

Shaft Diameter Range

• 40 mm to 420 mm

Located & Non-Located Bearing Housing Options

JAYCO SBD housings are available in both:

• Located bearing housing arrangement
• Non-located bearing housing arrangement

Unlike conventional housings, no locating ring is used. Bearing positioning is achieved through precision-machined cover steps for accurate axial location.

Note: Located or non-located arrangement must be specified during ordering.

Advanced Sealing System for Dust Protection

Triple Groove Labyrinth Seal – Standard TS Type

JAYCO SBD housings feature a robust labyrinth sealing arrangement designed for superior contamination protection.

Benefits of Labyrinth Seals

• Prevents dust ingress
• Protects against moisture contamination
• Minimizes entry of foreign particles
• Suitable for dirty industrial environments

The labyrinth ring rotates with the shaft and is securely fixed using a spring ring arrangement.

Optional Taconite Seal

Heavy-duty Taconite sealing arrangement available for:

• Mining industries
• Cement plants
• Highly dusty operating conditions

Grease Lubrication System

• Designed exclusively for grease lubrication
• Grease nipples provided for easy relubrication
• Supports long operational life with reduced maintenance

Easy Installation & Condition Monitoring Features

Installation Advantages

• Eye bolts provided for safe lifting and handling
• Precision-machined base pads ensure:
  • Easy alignment
  • Uniform load distribution
  • Stable mounting

Optional Monitoring Features

Provision available for:

• Temperature sensors
• Vibration monitoring probes
• Predictive maintenance systems

Ideal for modern condition monitoring applications.

SBD Series Dimensional Range
