Featuring Bearing Type: Radial Bearings
The purpose of a radial bearing is to reduce rotational friction and support loads. This is achieved by using two races to hold the balls and to spread the load through the balls. As the bearing race rotates it causes the balls to rotate. The ball provides for substantially less rolling resistance and coefficient of friction than if two flat surfaces were rotating...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 »
Featuring Bearing Application: Turbine Flow Meter
Flow meters provide replicable and exact measure of linear, nonlinear or volumetric flow rate of a liquid or a gas. Turbine flow meters, or axial turbines, translate the rotating turbine action around an axis into a readable rate of flow. These types of meters are typically used for oil and gas measurement in pipelines where the density of the fluid depends greatly upon pressure, temperature and the gas composition.

To ensure a long life for flow meters it is crucial that the meter has been installed with the proper bearing material depending on the fluid lubricity and operating temperature. Many turbine meter installers prefer ceramic bearings for their superior design and durability. Ceramic bearings are a substantial upgrade over traditional steel bearings for many turbine flow meter environments...more »
Lightning Lube Technology is specially designed to form a molecular bond with all moving metal parts within any application. Use it to reduce friction, improve performance, decrease wear and extend life. Lightning Lube can be used when installing new bearings and components or to preserve your existing bearings and components..more »
Q: What does Radial Play mean?

A: Radial Play refers to the fit or clearance of the balls in the bearing. The normal range is from C2 to C5. C2 would be the tightest fit and would not have much room allowed for expansion of the balls or misalignment. C5 would be the loosest, where the balls are undersized to allow for some expansion as the bearing heats up or misalignment of the application.
