How To Guarantee You Are Choosing the Correct Bearing

Any industrial company knows that bearings are essential parts in the running of virtually all machinery and equipment, but when it comes to getting a replacement, it can get difficult. At Quality Bearings Online, we understand how frustrating it can be trying to get the correct bearing, so we’ve outlined a few key elements to consider to make sure you get the right part every time.

Part Numbers

It might seem like bearing manufactures have written in secret code, in fact they don’t just use these codes to confuse you. The part numbers tell you your bearing’s exact specifications, as each digit in the part number designates key features of the bearing. Things like the bearing’s internal diameter, the cage material, and the internal clearance are all outlined simply by understanding the part number.

Each manufacturer has their own part numbering system, and while there are some overlaps, it is not consistent, so it’s vital you check before choosing a different brand. Manufacturers could even use the same suffixes to designate different parts, meaning even if they list the same suffix in the part number, they might be referring to different specifications.

If you are unsure about which bearing you need based on the part number, our product pages display a handy table with a breakdown explaining what each part means or contact us and we can cross reference for you.

Seals and Shields

There is often confusion around bearings with a single seal or shield and bearings with a seal or shield on both sides. For a sealed bearing, the part number is stamped on the seal itself, and it will only have the part number for a single seal even if the bearing does in fact have two. When finding the right part number, start by checking your bearing to confirm the number of seals or shields you need and then check the product details before purchasing to make sure the new one has the correct number of seals.

Measuring

When measuring your bearing, it is vital that you are accurate, so it is highly recommended to use a vernier caliper. The dimensions you need to are the inner and outer diameter and the width.
