Electric Motor Quality (EMQ) Bearings

Boca Bearings offers a full line of deep groove, Electric Motor Quality (EMQ) bearings. Electric Motor (EMQ) bearings are designed and and Noise Tested (NT) to a noise quality standard. All EMQ Bearings are available in C3 Fit (with limited sizes available in C4 fit). We now stock 8MM (Milimeter) to 100MM Bores in the 6000, 6200, 6300, 6800, 6900 series. We allso offer Standard and specialty Metric/Inch bore sizes in 1/2, 13MM, 16MM, 5/8, 3/4, and 1. 

We have expanded our Electric Motor Quality (EMQ) Bearing offering to include our new Ceramic Hybrid C-HIP series. C-HIP bearings utilize ceramic balls that are made with Hot Isostatic Pressing (HIP). These ceramic balls have an even greater density and hardness than a standard ceramic ball.

We offer three versions to Choose From Metal Shields (ZZ) for Speed Applications. Contact Rubber Seals (VV) for Moisture Applications, FKM Seals (2VS Viton) For High Temp Applications.

Please note we offer larger size EMQ Bearings from 65MM Bore to 100MM in our Standard Ceramic Hybrid Series.

  • Chrome Steel Series

    Chrome Steel Series

    Chrome Steel 52100 Series Electric Motor Qulaity (EMQ) bearings contain chromium and, due to thorough hardening, have excellent surface quality and high load capability. 52100 Chrome Steel Radial Bearings are a universal material for many applications. Chrome Steel is magentic.

  • Stainless Steel Series

    Stainless Steel Series

    Stainless Steel 440C Series Electric Motor Quality (EMQ) Bearings contain a martensitic-type stainless steel used extensively in bearing applications that require hadrness, dimensional stability, corrosion resistance and toughness. Stainless Steel 440C is resistant to corrosion from fresh water, steam, crude oil, gasoline, perspiration, alcohol, blood and food stuffs. Stainless Steel does contain some carbon so it is still slightly magnetic and may eventually rust.

  • Ceramic Hybrid Series

    Ceramic Hybrid Series

    Ceramic Hybrid Electric Motor Quality (EMQ) bearings have steel races and ceramic balls. Ceramic balls are suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Ceramic is non-porous, non-magnetic, non corrosive and lighter than steel. In ball form, ceramic balls are also harder than steel and because ceramic balls are non-porous they are virtually frictionless and capable of spinning faster than steel balls.

  • Ceramic Hybrid C-HIP Series

    Ceramic Hybrid C-HIP Series

    The C-HIP Ceramic Hybrid EMQ Bearings are similar to our Ceramic Hybrid series, but these C-HIP bearings utilize Si3N4 Ceramic balls that are made with Hot Isostatic Pressing (HIP). These ceramic balls have an even greater density and hardness than a standard ceramic ball. Ceramic Hybrid bearings have steel races and ceramic balls. Ceramic balls are suitable for applications where high loads, high speeds and extreme temperatures are factors.
