Electrical-Insulating Unthreaded Spacers

Stop electrical current in its tracks—these nonconductive spacers prevent it from passing through your components. They’re often used to insulate circuit boards and enclosures.

Ultra-High-Temperature Grade L5 Ceramic—Our most heat-resistant spacers, even at blistering temperatures up to 1700° F. However, they may crack or dent if subjected to hard bumps and vibrations.

Insulating Sleeve Washers

Cover screw threads to stop electrical current in its tracks and prevent short circuits. These washers create a barrier between the screw threads and the mating surface when mounted in through holes. This barrier also extends the life of your assembly by preventing galvanic corrosion, which is when two different metals rust more quickly due to contact with each other.

Flat Edge

The flat edge distributes weight evenly to take pressure off screw heads.

Extra-High-Temperature Ceramic—Our most heat-resistant washers and the best electrical insulators. These won't melt or become brittle at blistering temperatures up to 1,700° F, making them perfect for ovens, kilns, and furnaces. Ceramic may crack or dent if subjected to hard bumps, however, so these washers are not recommended for high-vibration applications.

Ultra-High-Temperature Ceramic Washers

Our most heat-resistant washers, even at blistering temperatures up to 3000° F. They distribute pressure evenly under nuts and screws in industrial furnaces, kilns, and other extreme-temperature environments. Ceramic may crack or dent if subjected to hard bumps, however, so these washers are not recommended for high-vibration applications.

Material Certificate—Washers include a report with a traceable lot number.

Insulating Cup Washers

Cover screw heads or nuts to block electrical current and prevent short circuits. These washers isolate fasteners from sensitive surface-mounted components, such as capacitators and transistors on printed circuit boards. They also extend the life of your assembly by preventing galvanic corrosion, which is when two different metals rust more quickly due to contact with each other.

High-Speed Ultra-Thin Linear Sleeve Bearings

Use these ultra-thin sleeve bearings in high-speed applications where clearance is a concern. They have a ceramic liner to achieve high speeds and allow rapid acceleration and deceleration. Pair them with round end-supported shafts. These fixed-alignment bearings are for use where shaft misalignment is unlikely. To install, slide them into a housing (not included).

Linear Sleeve Bearings

Bearings are for use with round end-supported shafts. To install, slide bearings into a housing (not included) and secure with two retaining rings (sold individually).

Self-Aligning with 2° Misalignment Capability

PTFE Liner

Self-aligning bearings compensate for shaft misalignment.

PTFE Liner—PTFE-lined bearings are chemical resistant and nonabrasive. They have a ceramic coating for added corrosion resistance.

0.001" Shaft Clearance—Bearings with 0.001" shaft clearance are less likely to bind on your shaft than bearings with 0.0005" shaft clearance.

0.0015" Shaft Clearance—Bearings with 0.0015" shaft clearance are less likely to bind on your shaft than bearings with 0.0005" shaft clearance.
