SPB’s solid lubricant bearing sizes are available from 1/8” inner diameter to 1” inside diameter, and from metric 10mm to 50mm inside diameter. Most sizes come in chrome steel or stainless steel. Orders received at the Sarasota facility by 2:00pm EST usually ship the same day. (read more)
When bearings rotate, the inner and outer rings and rolling elements are constantly loaded. This produces material fatigue and eventually bearing failure. The total number of revolutions before a failure occurs is called the basic rating life.
Life of individual bearings varies considerably, even if they are of the same size, same material, same heat treatment... (read more)
The lubrication method and the lubricant have a direct effect on the bearing life; the most suitable lubrication must therefore be selected for each application. Effects of lubrication are described as follows:
(1)DECREASE OF FRICTION AND ABRASION It decreases rolling friction between the raceway and the rolling elements, sliding friction between rolling element and cage an... (read more)
Each bearing type has its own limiting speed. The theoretical speed that bearings can run at safely, even if heat generation by internal friction occurs, is called the maximum permissible speed.
The permissible speed is related to bearing type, type of cage, lubricant type, load and cooling conditions to which the bearing is subjected.
For contact rubber seals(2RS type), th... (read more)
Standard material for rings and balls is a vacuum degassed high carbon chromium steel allowing for high efficiency, low torque, low noise level and long bearing life. For bearings requiring anti-corrosion or heat-resistance properties, martensitic stainless steel is used.
