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.
Heat Wands
Shaped like a large flashlight, this wand loosens stuck nuts, heats bearings, and repairs dents. It uses magnetic induction to heat but does not magnetize parts.

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 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.

Low-Melting-Point Lead-Free Solder for Low-Temperature Applications
Made of indium, this solder is soft and malleable—even as temperatures approach absolute zero—to form an airtight seal between metal and certain non-metal materials. It’s commonly used in cryogenic applications, including with liquid nitrogen. Unlike tin-based solders, this solder won’t damage gold plating on circuit boards. It’s a good conductor of heat and electricity, as well. Indium-based solder can be cold welded, meaning it will bond to itself without heat. 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. Use soldering flux to prepare workpieces for this solder.
100% indium solder 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.
48% tin solder has greater tensile and shear strength than 100% indium solder, but lower thermal and electrical conductivity.

Low-Melting-Point Solder for Low-Temperature Applications
Made with lead and silver, this solder has greater tensile strength and density than other indium-based solders, giving it a stronger hold. Indium is soft and malleable—even as temperatures approach absolute zero—allowing this solder to form an airtight seal between metal and certain non-metal materials. It’s commonly used in cryogenic applications, including with liquid nitrogen. Unlike tin-based solders, this solder won’t damage gold plating on circuit boards. It’s also a good conductor of heat and electricity, although not as good as solder with greater indium content. Indium-based solder can be cold welded, meaning it will bond to itself without heat. 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.
