Electric Motor Quality Bearings (EMQ) are designed specifically for Electric Motors. Whether it be high speed brushless RC motors, Power tools or multiple other purposes, these bearings are designed for low noise, high precision & Longevity. Options for bearing type and seal type will vary depending on the bearing size. Prices are for individual bearings.
This listing contains a very broad range of bearings for many different applications. Each bearing is
SOLD INDIVIDUALLY in quantities of 1. The bearings are listed by size & Bearing Number, for example 5x10x4mm - 105.
Once the model is selected you can then select the Bearing Type which will only display the available options depending on which model you have selected. We have an explanation for each bearing type below.
You can then select the Seal Type which will display the options available for the options that have been selected in the first 2 boxes.
Please contact us if you are unsure of what bearings are required to suit your application, the bearings on this listing are used in hundreds of different applications and some will be better suited than others.
Chrome Steel
SAE 52100 Chrome Steel is the most common material used in deep groove ball bearings. This type of steel is useful in most applications, it's not recommended for use in fishing reels or any environment where it is exposed to water, it has low corrosion resistance.
Advantages are high hardness for long life, low cost for high performance, operates at temperatures up to 150c, lower noise and higher hardness compared to stainless steel.
When selecting this option, you are receiving an ABEC 3 rated chrome steel bearing that is pre-lubricated and ready to use.
Hybrid Ceramic
Our Hybrid Ceramic Bearings are constructed with Chrome Steel Rings and Si3N4 Ceramic Balls. There are many different options on this listing, some have chrome steel retainers whilst others have PA46 Nylon retainers, the ABEC ratings vary depending on which option is selected. Please contact us if you would like information on a particular bearing, we also have all bearings listed individually on our eBay store.
Hybrid Ceramic bearings can run at higher RPM's than steel bearings due to the lower centrifugal force generated by ceramic balls, they are lighter and harder than steel. Ceramic bearings are less subjected to ball skidding under initial torque / acceleration and they do not suffer from heat expansion. These 2 factors contribute to wear and when used in the right conditions a ceramic bearing will outlast chrome steel or stainless bearings.
Ceramic balls are corrosion resistant and non magnetic.
PTFE Contact Rubber Seals
The PTFE Rubber is bonded to a metal washer, the inner lip of the seal makes contact with the inner ring of the bearing to provide an effective seal against smaller particles such as dirt and dust, whilst protecting the lubricant from contamination and from leaking.
PTFE Non-Contact Rubber Seals
This is the same as above except the rubber does not contact the inner ring, this is only used in our Hybrid Ceramic Premium Bearings.
Non-Contact Metal Shields
Metal Shields are designed to prevent larger particles from entering the bearing and providing a barrier to prevent grease from escaping. This seal type allows for higher RPM's
