The ultimate buying guide of bearings

A bearing is a mechanical component that helps a rotating assembly move smoothly. As a result, the bearing permits one element to rotate relative to another. Bearings are high-precision elements that enable equipment to move at various speeds while efficiently transferring significant loads. They must be able to perform at high speeds with low noise and vibration while maintaining great precision and durability. There are numerous bearing uses in different industries.

 

This type of device can be found in a variety of industries, including the automobile industry, aircraft, construction equipment, machine tools, and so on.

 

Ball bearings, cylindrical roller bearings, tapered roller bearings, and needle bearings are the four most common types of bearings.

 

While ball bearings are the most popular mechanism, each has its own set of benefits and drawbacks. As a result, we recommend comparing each of these bearings to determine which system is best for your needs.


 

This guide covers the fundamental factors that influence the cost and performance of a bearing, allowing you to make an informed decision when purchasing your next set. It includes information on the following topics:


 

  • Size
  • Materials
  • Rating
  • Ball count
  • Sealed vs. Serviceable

 

Size

 

A large proportion of skating bearings are sized for 8mm axles; these are also known as standard 608 bearings. In comparison, 7mm (627) bearings are relatively uncommon, while other sizes such as Micro (688) are only rarely seen. We recommend purchasing the size that your axles and wheels are designed to use as the only true restriction when it comes to bearings.

 

Materials

 

Bearings perform best when friction is low, so materials are essential in performance. Many bearings are made of steel alloys that are both strong and inexpensive. Search for bronze, titanium, and, especially, ceramic components or coatings, as these will improve a bearing's resilience, durability, and performance.  Ceramic bearings are widely considered to offer the finest value for money.

 

Rating

 

Many manufacturers look for an ABEC rating, which ranks bearings from 1 to 9. The method was designed for industrial uses, not skating, therefore higher ABEC scores indicate a more perfectly constructed bearing. As a result, some businesses forego ABEC ratings on skate bearings in favour of "skate rated" labelling, which indicates that the bearing has been tested and authorised for skating.

 

Ball Count

 

Skate bearings feature seven balls in them, which provide an excellent blend of acceleration, top speed, roll, and longevity. Six ball bearings include larger balls that generate less friction and roll for longer, making them ideal for skating at high speeds for lengthy periods of time (think 27-in-5 or banked track). Smaller balls in eight ball bearings tolerate side loads better, making them ideal for high-speed or violent turning (think park skating).

 

Sealed vs. Serviceable

 

Serviceable bearings have removable shields or plastic retainers that allow you to clean and re-lubricate your bearings. Most high-end bearings are serviceable, allowing you to maintain optimal roll and extend bearing life. Sealed bearings have non-removable shields that help keep out harmful debris, but they cannot be cleaned and must be replaced if they are not performing as expected. Sealed bearings are ideal for skaters who do not want to deal with bearing maintenance but lack the performance of serviceable bearings.
