BJ150 Coupling for Rolling Mills Feeding Machinery and Conveyors
The BJ150 is a fixed type ball cage coupling built for the metallurgical environment, where shock loads, vibration and heat are constant. It transmits high torque through misalignment without needing frequent maintenance, which is what keeps it in service on mill and conveyor drives.
- Fixed type BJ series coupling, size 150
- High strength alloy steel construction
- Precision ground bearings with advanced sealing
- For rolling mills, feeding mechanisms and conveyors
Key Benefits
Why plants standardise on this size.
Reliable Under Shock And Heat
Resistance to impact, vibration and high temperature is what allows the coupling to stay in a mill drive rather than being changed each campaign.
Protects The Equipment Behind It
By absorbing misalignment the coupling protects connected gearboxes and bearings from wear.
Lower Maintenance Cost
No need for frequent maintenance means fewer planned interventions and less downtime around the drive.
Where It Is Used
Drive positions.
- Rolling mill drives
- Feeding mechanisms in metallurgical plants
- Conveyor drive lines
- Heavy machinery with shock loading
Who It Is For
- Mill maintenance teams
- Plants standardising on one coupling size
- Rebuild shops replacing failed couplings
- Buyers looking for an alternative source on BJ150
Problems It Solves
- Coupling failures under impact and vibration
- High maintenance frequency on drive couplings
- Wear transferred into gearboxes by rigid connections
- Downtime waiting for a replacement coupling
Technical Features
Construction.
High Load Carrying Capacity
Designed to transmit torque that meets or exceeds the demands of most metallurgical machinery.
Precision Ground Bearings
Ground bearing surfaces with advanced sealing resist wear and fatigue in dusty hot conditions.
Alloy Steel Body
High strength alloy steel construction is what supports the shock load capability.

Manufacturing Process
Duty Confirmation
Torque, speed, misalignment and ambient conditions at the drive are reviewed.
Machining
Coupling halves and interfaces are machined to the shaft drawing.
Heat Treatment And Grinding
Bearing surfaces are hardened and ground for fatigue life.
Sealing And Assembly
The coupling is greased, sealed and checked before packing.
Quality Control

How It Compares
BJ150 against other couplings on a mill drive.
| Cross shaft universal joints | Ball cage construction transmits constant velocity and tolerates shock better in mill duty. |
|---|---|
| Gear couplings | Handles misalignment and impact with less frequent maintenance in dusty hot areas. |
| Larger coupling sizes | BJ150 is sized for the torque band that most mill and conveyor drives need, without oversizing the drive envelope. |

What is the BJ150 used for?
Rolling mills, feeding mechanisms and conveyors in metallurgical plants, where shock loads, vibration and heat are present.
What is it made from?
High strength alloy steel with precision ground bearings and advanced sealing for wear and fatigue resistance.
How much maintenance does it need?
It is designed to avoid frequent maintenance. Regular re greasing at the interval set for your conditions is normally sufficient.
Can you machine it to our shaft?
Yes. Send the shaft drawing with bore, keyway and installed length and we finish the interfaces before shipment.
Do you supply other sizes in the series?
Yes, BJ150 is one size in the fixed type BJ series. We can select another size if the torque and envelope require it.
What do you need to quote?
Torque and speed, shaft dimensions, installed length and the ambient conditions at the drive.
