About Bearing Heaters
Heating bearings makes them easier to install and reduces damage to shafts during installation. Heat expands the bearing's inner race for a snug fit without forcing a tight-fitting bearing onto a shaft. Bearing heaters can also be used on gears, sprockets, pulleys, and bushings. Induction bearing heaters use magnetic induction to heat but do not magnetize parts.

Ultra High-Temperature Molybdenum Wire
- Hardness: Rockwell C59 (Very Hard)
Able to handle high melting points and conduct heat and electricity, this 99.95% pure molybdenum wire is often used in lights to create a support for filaments. It resists oxidation and won’t corrode. Molybdenum is better at conducting heat and electricity than tantalum and platinum, which also have high melting points. It is not, however, as corrosion resistant.

Platinum Wire
- Hardness: Rockwell B97 (Medium)
99.95% pure, this platinum wire is used for applications that require a soft material that resists corrosion and oxidation and has a high melting point. This wire allows heat and electricity to pass and resists oxide buildup, making it ideal for thermocouple probes, which require accurate readings even at high temperatures. Soft enough to create a good seal between two flanges, it's also used to make high-vacuum O-rings. Platinum's softness means it won't damage the flanges, so they can be used again. The high melting point of this wire makes it a better choice for sealing heated flanges than other materials such as gold.

Ultra-High-Temperature Niobium Wire
- Hardness: Rockwell B70 (Medium)
This niobium wire has a higher melting point than most other metal, so it’s also known as refractory metal. It's highly conductive, corrosion resistant, and maintains its strength even at high temperatures. At low temperatures, it becomes a superconductor. This wire holds up in a variety of tough conditions including jet engines, pipelines, and semiconductor manufacturing.

Low-Melting-Point Solder for Low-Temperature Applications
Even as temperatures approach absolute zero, this indium solder remains soft and malleable, allowing it to form an airtight seal between metal and certain non-metal materials. It’s often used in cryogenic applications, including those with liquid nitrogen. This solder has a lower melting point than most solders, so it’s good for sensitive assemblies, such as semiconductors and electronic components. Unlike commonly used tin-based solders, this solder won’t damage gold plating on circuit boards. It’s also a good conductor of heat and electricity. More durable than standard tin-lead solder, this solder is less likely to crack from repeated temperature swings. It’s low outgassing, so it’s good for use in high-vacuum applications.
This indium-based solder can be cold welded, meaning it will bond to itself without heat. You can also use it for step soldering with traditional solders. It does not have a flux core; choose soldering flux to prepare workpieces for this solder.
Leaded solder has greater tensile strength and density than other indium-based solders, giving it a stronger hold.
Lead-free solder is safer to use than leaded solder and helps meet industry regulations. Solder that is 100% indium has better thermal conductivity than solder that contains tin, and will cold weld more easily. However, it has lower tensile and shear strength than solder with tin. Solder with 48% tin has greater tensile and shear strength than 100% indium solder, but lower thermal and electrical conductivity.
