What are the Best Precision Bearings?

Is your industrial or commercial operation highly demanding and need special bearings? One of the top choices is precision bearing. These are bearings made to deliver the highest possible efficiency in power transmission and sports such as skating. This means they are precise, have low-vibrations, and release low-noise levels. And that is not all; they are capable of absorbing high loads.

 

The design of precision bearing focuses on delivering the highest possible accuracy and tolerance, in comparison to the regular models of rolling bearings. Here is a closer look at some of the best precision bearings; ABEC-5 bearings and ABEC-7 bearings.

 

A Closer Look at the ABEC Bearing Classification

Before looking at the best bearings, let us take a peep at their classification. Why ABEC? What is ABEC? In the US, the standards of bearings are maintained by the American Bearing Manufacturers Association (ABMA). Under ABMA falls the Annular Bearings Engineers Committee (ABEC) that defines the tolerances of bearings. This is why bearing tolerances are referred to as ABEC grade/ rating.

 

The high precision bearings, ABEC rated bearings, fall in five categories, ABEC 1, ABEC 3, ABEC 5, ABEC 7, and ABEC 9. Now that we have demonstrated the classification, we will now look at the best two precision bearings.

 

Best ABEC-5 bearings

 

When grading ABEC bearings, one of the crucial factors considered is eccentricity. This is the roundness of the inner ring. In the case of ABEC-5 bearings, the maximum eccentricity allowed is 0.0035 mm. The bearings can be designed with steel, ceramic and titanium. They are used in applications such as metal cutting spindles, high-speed turbochargers, and skateboards.

 

Bones bearing reds bearings

 

This bearing has cut a name on the market for high reliability. They have rubber shields and nylon ball retainers for extra strength and speed. However, the inner race does not have a groove.

 

Spitfire burner bearings

 

For those targeting high precision bearings ABEC-5 bearings at an affordable rate, one of the top options is Spitfire burner bearings. The bearing is designed with nylon cages and steel rings that make it very durable.

 

Bone bearings super reds bearings

 

This is another high precision bearing designed with steel balls and races. It also features spacers, washers, and rubber shields that make it very quiet.

 

Bones Swiss ceramics bearings

 

If you are looking for speed, strength and highly reliable bearings, look no further than the bones Swiss ceramics bearings. It is designed with light-weight and non-corrosive ceramics balls.

 

Best ABEC-7 bearings

 

ABEC-7 bearings have a maximum eccentricity of 0.0025 mm and are designed with materials such as steel, ceramics, titanium, and plastic in some cases. When compared with ABEC-5, ABEC-7 bearings have higher speed and better performance. This is the main reason why the cost is also higher. Some of the main applications that use ABEC-7 include high-speed rolling mills, vacuum pumps, precision ball screws, balancing machines, and live centers. Good examples of the best ABEC-7 bearings include:

 

Bear Trucks ABEC 7 Ceramic Spaceballs Bearings

 

These bearings are designed with extended inner rings that reduce the need for speed rings. The bearings are mainly designed using super-hard steel ball bearings. They are sold in packs of eight.

 

RADECKAL Blue ABEC 7

 

The bearings are designed using steel and are pre-lubricated. They are recommended for standard skateboarding.

 

Radeckal Blue ABEC 7

 

This is another high-performance bearing that has become very common in the market today. They are designed with steel and are pre-lubricated for smooth and quiet operations.

 

Wicked ABEC 7 Freespin 608

 

These bearings are designed using freespin technology to guarantee optimal rolling speed. The bearings are made of steel and feature a unique rubber shield for easy maintenance.

 

If you have a highly demanding operation that needs special bearings, using the standard bearings will be counterproductive. Go for the best ABEC rated bearings such as the ABEC-5 and ABEC-7 models.
