Rod End Bearings, also known as a heim joint (N. America) or rose joint (U.K. and elsewhere), are a mechanical articulating joint. Rod End Bearings are used on the ends of cylinders, linkages, rods, and shafts to take up misalignment between connected parts. They consist of a spherically-shaped inner ring and a cylindrical bore for mounting on a shaft. Rod End bearings attach to rods and shafts via a male stud with external threads or a female housing with internal threads. Right-handed threads tighten in a clockwise direction and are the most commonly used type of thread. Left-handed threads tighten in a counterclockwise direction and must match the mating part...more »
Industrial lubricants are oils, greases and other substances designed to reduce friction, binding or wear. Specialized characteristics may enhance thermal conduction or reduce electrical resistivity. Other industrial lubricants can provide sealing against moisture. Industrial lubricants are available in many forms such as low viscosity oils..more »
Boca Bearing Company is introducing a new line of full ceramic bearings, ceramic hybrid bearings and lubricants catered towards the automation and advanced manufacturing industries. Boca Bearing’s ceramic bearings can be used in varieties of manufacturing environments ranging from extreme temperatures, high speeds to heavy loads.

The wide array of features of full ceramic and ceramic hybrid bearings allows for application flexibility. Engineers can upgrade and downgrade machines, seamlessly integrating them into different production lines without long waiting times, maintenance and without production down times. Deep groove bearings, thrust bearings, angular contact bearings and self-aligning bearings are just some of the styles available in Full Ceramic and Ceramic Hybrid versions...more »

Lightning Lube can be used when installing new bearings and components or to preserve your existing bearings and components..more »
Q: How do I properly spin test my fishing reel bearings before installation?

A: We always suggest testing ceramic bearings by putting them under load. Fishing reel bearings are relatively small and ceramic is much lighter than steel so there is just not enough mass to see a prolonged free spin without a load attached to the bearing. The flick test seems to result in a perception that a ceramic bearing does not spin as long as a steel bearing, but as soon as you put both bearings under load the difference is noticeable. New bearings will require a short break in period, so comparing new bearings to old worn in bearings is not an apples-apples comparison. We typically just attach an awl to a bearing and give it a spin like shown in this spin test video.
