SBD Series Bearing Housings

Heavy-Duty Non-Split Plummer Blocks by JAYCO Engineering India

Engineered for Extreme Belt Conveyor & Heavy Processing Applications

JAYCO SBD Series Bearing Housings are heavy-duty, non-split, single-piece bearing housings, originally developed for high-load belt conveyor drives and now widely used across crushers, sugar mills, mining, wind power, wagon tipplers, rotary drums, and bulk material handling systems.

Designed to withstand very high static and dynamic loads in radial and axial directions, JAYCO SBD housings deliver exceptional structural strength, operational reliability, and long service life in the most demanding industrial environments.

Why Choose JAYCO SBD Series Bearing Housings?

Built for Load. Built for Shock. Built for Reliability.

JAYCO SBD housings are preferred where:

Heavy belt tension and shock loads are present

Continuous operation is critical

Minimal maintenance is required

Extreme vibration and harsh environments exist

Their robust design makes them a proven solution for heavy processing industries and conveyor systems.

Key Engineering Features of JAYCO SBD Series

✔ Non-Split, Single-Piece Construction

Eliminates joint weakness found in split housings

Provides maximum rigidity and load-bearing capacity

Suitable for severe duty applications

✔ Dual Cover Design

Covers provided on both sides of the housing

Covers held by suitable high-strength bolts

End cover option available for closed-shaft arrangements

✔ Heavy & Hollow Base with Reinforced Ribs

Thick ribs on both sides of the housing

Designed to resist deformation under heavy radial loads

Provides excellent stability under dynamic operating conditions

✔ High Load Carrying Capability

Capable of withstanding high static and dynamic loads

Performs reliably in both radial and axial load directions

Bearing Compatibility & Shaft Range

Suitable for spherical roller bearings

Accepts both:

Adapter sleeve mounting

Cylindrical bore bearings

Shaft diameter range: 40 mm to 420 mm

Located & Non-Located Bearing Options

No locating ring is used in SBD housings

Bearing location achieved by precision-machined cover steps

Must be specified at the time of order:

Located bearing housing

Non-located bearing housing

This ensures correct axial positioning of the bearing inside the housing.

Advanced Sealing & Lubrication System

✔ Grease Lubrication (Standard)

Designed for grease lubrication only

Grease nipples provided for periodic relubrication

✔ Triple-Groove Labyrinth Seal (Standard)

Complex labyrinth sealing arrangement for superior protection

Labyrinth ring secured on shaft using spring ring

Ensures seal rotates with shaft while grooves remain guided in cover

Provides excellent resistance against:

Dust ingress

Moisture

Foreign particles

Standard Seal:
Labyrinth Seal – TS Type

✔ Optional Taconite Seal

Heavy-duty Taconite seal available with special modification

Recommended for mining, cement, and extremely dusty environments

Installation & Handling Advantages

Eye bolt provided for lifting and safe handling

Precisely machined base pads for:

Easy alignment

Uniform load distribution

Optional holes for:

Temperature probes

Vibration sensors

This makes SBD housings ideal for condition monitoring systems.
