Electric Motor Quality Bearings

Electric motor quality bearings are made to higher standards to ensure motors rotate smoothly, quietly, and efficiently, carry higher load capacity, have long life spans, and produce low running noise. These properties are critical in electric motors. We carry bearings for any type of electrical motor. Some of these include AC and DC motors, gear motors, brush motors, brushless motors, stepper motors, and linear motors and many, many more. A few of the different types of bearings include angular contact, cylindrical roller, needle roller, spherical roller, and tapered to name a few. These bearings must also be lubed to electrical motor standards.

Our Supply

Angular Contact Bearings- These bearings provide great resistance to the wear and tear of high-speed applications while also accepting radial and thrust loads. These can also be high precision bearings.

(Fafnir 2MM & 3MM SERIES, SKF NU SERIES, 7000, 7200, AND NSK 71000 SERIES ABEC 7 AND 9 options.)

Needle Roller Bearings- Needle rollers are generally open on the inside and have a solid cage on the outside. They can come with an inner ring. An overview of needle bearings includes standard full complement and caged needle bearings, cam followers, and roller followers to name a few. This type of bearing handles high loads very well and can withstand oscillation with greater rigidity. These come in a variety of sizes and are available in chrome, stainless steel, or black oxide material.


Spherical Roller Bearings- Spherical Roller Bearings are designed to help when misalignment exists whether from mounting or shaft deflection. These bearings can handle heavy radial loads and some axial loads in either direction. They also do very well with shock loads. Since these are self-aligning, they can handle full capacity loading despite shaft deflection. Another advantage of spherical roller bearings is they are designed to carry heavier loads but at lower maximum speeds. These usually come with standard straight bores but are also available with tapered bores.

(21300, 22200, 22300, 23000, 23100, 23200, are types of spherical roller bearings)
