Bearing Heaters – Stocked for the Trade
Bearing heaters make fitting large or interference-fit bearings faster, safer, and more precise. By expanding the inner ring through controlled heating, they allow shaft mounting without brute force, hammer damage, or distortion.
Whether you’re installing one bearing or a dozen, a heater saves time and protects the job.
Godiva Bearings stocks ConeMount bearing heaters — trusted by fitters and maintenance teams across the UK. Built to work. Built for trade.
What Are Bearing Heaters?
Bearing heaters are tools used to expand bearings using heat, making them easier to mount onto shafts.
They:
- Eliminate the need for hammers or presses
- Prevent brinelling and raceway damage
- Provide uniform, repeatable expansion
Godiva supplies:
- ConeMount bearing heaters: Tapered aluminium cones for efficient heat transfer
- Induction heaters (on request)
- Contact thermometers and gloves for safe handling
What Are They Made Of?
Our ConeMount bearing heaters are manufactured with:
- Aluminium alloy cones – Lightweight, fast-conducting, and tough
- Electrical resistance elements – Built into the core for consistent heat
- Adjustable bases and thermal switches – For user safety and repeatability
Available for:
- Bearings with 15mm to 305mm bore
- 110V or 240V supply
- Portable or bench-mounted use
Where Are Bearing Heaters Used?
Bearing heaters are used wherever interference-fit bearings need to be mounted without damage. Trade applications include:
- Plant maintenance: Reducing downtime during planned bearing replacements
- OEM assembly lines: Repeating high-volume, damage-free installs
- Motor and gearbox repair: Safely mounting new bearings to shafts
- Power generation: For turbines, alternators, and pump systems
- Pulp and paper: In mills with high-speed rotating assemblies
- Marine engineering: Where access is limited and precision is critical
If it rotates under load, it deserves a proper fit.
What Do They Help Prevent?
Using a bearing heater helps prevent:
- Bearing damage from hammering or cold pressing
- Misalignment due to uneven expansion
- Race deformation or internal scoring
- Safety risks from uncontrolled install methods
- Costly rework or premature failure
It’s not just about fitting easier — it’s about fitting right.
Installation, Use and Maintenance Tips
Trade best practice:
- Clean the bearing and cone before heating
- Don’t overheat – stick to manufacturer temperature limits (typically 110–130°C)
- Use gloves and tongs when handling heated components
- Monitor temperature with a probe or indicator
- Let the heater cool before storing
Never use open flame. It’s not the 1960s.
Conclusion: Heat Smart. Fit Right.
Bearing heaters make precision fits simple. No damage. No guesswork. Just safe, reliable installation every time.
