Bear-N-Bronz is Boston Gear general purpose, cast, solid bronze bearing material. It is a high grade, leaded tin bronze, having good hardness, strength, wear-resistance and exceptional anti-friction qualities. It is particularly suited for moderate to heavy loads at normal to relatively high speeds. All parts are rigidly inspected to assure freedom from porosity and conformance to dimensional tolerances. In addition, our standard product offering, the Bear-N-Bronz material can be provided in different sizes, bar lengths (up to 105"), and with oil grooves.

Excellent customer service

The couplings are just what they are supposed to be. But I wanted to comment on MRO. This was my first order with them and I was extremely surprised at how well the company is run. I will be doing more business with them in the future.

How do I choose the right type of bearing for my application?

Start with the load and how it’s applied. You need to know if you’re dealing with radial loads, axial loads, or a mix of both. Then look at speed, operating environment, and space constraints. For example, ball bearings are great for high speed and lighter loads, while roller bearings handle heavier loads but usually at lower speeds. If there’s contamination, moisture, or heat involved, you may need sealed bearings or specific materials. In most cases, the right choice comes down to matching load type, speed, and environment to the bearing design.
