What Are Bearing Inserts?

by | Mar 3, 2015 | Tips and Advice

When it comes to selecting the right bearing, there are several different possibilities to choose from. It’s good to have options, but sometimes it’s hard to keep track of which part does exactly what.

Bearing inserts are one of many different products we offer at Ritbearing, but what exactly do they do? Glad you asked!

WHAT ARE BEARING INSERTS?

Bearing inserts are adapted radial bearings. They are most commonly used in mounted unit applications in areas like agriculture, printing, and food processing. It’s common for bearing inserts to be sold with a housing, although they can also be a stand-alone product.

Bearing inserts features include:

• Easy re-greasing with Zerk fitting.

• Greater load bearing than standard single row or double row radial ball bearings.

• Housing that can be made from cast iron, thermoplastic, pressed steel, or stainless steel. Options also include nickel or zinc plated housings.

• An option for an anti-rotation pin, which further reduces rotation of the outside diameter of the bearing.

PRODUCT SPECIFICATIONS

If you’re looking into ordering some bearing inserts, then you’ll probably want to know exactly what you’ll be getting. Here’s a quick rundown on the specifications for our bearing inserts.

• Insert bearings can be made in 52100 chrome steel or 440 stainless steel.  Inserts can also be nickel or zinc plated.  Black oxide coatings are also available upon request.

• A variety of options to lock the bearing onto the shaft include: set screw locking collar, eccentric locking collar or a squeeze style collar.

• For normal applications, a Buna seal with a metal shroud shield is provided. For harsh environment applications, triple lip seals can be provided.

• Food grade greases can be made available upon request.

In order to provide our customers with the best bearing inserts available, we work with NBR, NKE, and RCBD (our very own Chinese Bearing Division) to meet your needs.
