Precision Ball Bearings

Shielded

For greater accuracy and higher speeds, these bearings are made to tighter tolerances than standard ball bearings.

Shielded bearings dissipate heat more efficiently than sealed bearings.

Electrically Insulated Ball Bearings

Shielded

Good for use in electric motors and power generators, these bearings have ceramic balls that insulate against stray current to prevent damage to the bearing. The ceramic balls generate less heat than steel balls, so they require lubrication less frequently.

Shielded bearings block out dust and other contaminants.

Stainless Steel Ball Bearings

Bearings are 440C stainless steel for good corrosion resistance.

Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
