Reference Chart<br />
The B15/16 Series is a thick-walled light-duty bearing used in many types of machinery to dampen vibration and shock loads. They are dimensionally interchangeable with<br />
most sintered metal bearings, and can be retro-fitted without changing the housing bore or shaft. Typically they’re used in agricultural and exercise equipment and machinery<br />
such as woodworking, packaging, and welding equipment.<br />
The B17/18 Series is available for situations where even the excellent abrasion resistance of the B19/20 Series is insufficient. It’s superior characteristics are especially well<br />
suited for high performance requirements. Applications include, for example, pneumatic cylinders, lifting equipment, fitness machinery, industrial brakes, clutches and<br />
automotive components in general.<br />
The B19/20 Series was initially designed for applications in chemical processing equipment. This material is a unique combination of exotic materials best suited for high load,<br />
temperature and speed applications. It is resistant to virtually any substance except for concentrated sulfuric acids. At present, this material is unique and unequalled.<br />
Applications include chemical mountings and pumps, oven manufacture, semi-conductors, film developing equipment, equipment for industrial-sized kitchens, etc.<br />
