Ball Bearing Selection Criteria Load There are basically two types of bearing loads: Radial and Thrust. For proper selection, the value of these loads must be determined. Service factors for applications can vary from uniform, light or heavy shock loads. The service factor for uniform loads is 1.0, for light shock loads use 2.0 and for heavy shock use 3.0 times the load. Speed When selecting bearings, the maximum speed published is intended as a guide. It is also generally assumed in life calculations that heavy loads are not applied at the maximum speeds, but rather light loads at high speeds and heavier loads at lower speeds. Heavy loads and high speeds will increase bearing operating temperatures which can effect the lubricant, seals and the cages or retainers. Bearing speeds are limited primarily by tolerance grade of bearing ball and raceway, lubricant, ambient conditions, retainer design, and type of bearing seal. Brand PTI Silver Series Ball Bearing Mounted Units have steel cages. The bearings are grease lubricated and have a steel slinger with a lip seal on each side of the bearing. Triple lip seals are also available. PTI Brand = Silver Series. PTI Gold Series Ball Bearing Mounted Units have a molded nylon cage. The bearings are grease lubricated and typically have a lip seal between 2 pieces of zinc plated steel. The limiting speeds are listed on the Ball Bearing pages. Our gold series is a popular European brand and marked as such. Life The L 10 Life is the expected life of a bearing based on normal conditions. Factors involving temperatures and ambient conditions, i.e. chemical, moisture and maintenance intervals are not factored into the basic formula. However they must be considered or factored into your selection criteria. To determine the L 10 hours of life for ball bearing use the following: L 10 = (C/P) 3 x 16667/rpm where: L 10 = Life hours. C = Dynamic capacity (lb). P = Equivalent Radial load. When P is a radial load only, then P = the actual radial load. If there is a thrust and radial load acting on the bearing, then these loads must be converted into an equivalent load. The equivalent load formula is: P = (X x F R ) + (Y x F A ) where P = equivalent load (lb). See table A, where: F R = radial load (lb), F A = thrust axial load (lb), e = thrust load to radial load factor (see table A), X = radial load factor (table A), Y = thrust factor (table A), Co = basic static rating. The first step is to find X and Y. Calculate F A /C O to determine e. Then calculate F A /F R and compare to e to determine the X and Y factors to use from table A. Next substitute all known values into P = (X x F R ) + (Y x F A ) equation. Then put the value of P into the L 10 life formula to determine the life hours of the bearing. Rpm is the shaft speed in revolutions per minute.

Aligned bearings run smoother, cooler, and quieter than misaligned units. Consequently, misaligned bearings will run hotter than aligned units. Cooler running bearings will operate longer than hot running bearings. Single Row ball bearings in housings will generally handle +/- 2% static misalignment but only slight dynamic misalignment. Spherical Roller bearings, as a comparison, can handle larger dynamic mislignments. Temperature / Lubrication Bearings that operate at higher temperatures may also experience a reduced life. There are no specific simple formulas to predict this, but a good understanding and experience of the application will help maximize bearing life. PTI Stainless Steel bearing inserts are lubricated with Mobil FM222 H1 Food Grade grease. A slight showing of grease purging from the seal area is optimal. When re-lubricating, small amounts of grease at frequent intervials is more desirable then large quanities infrequently. Re-lube while the bearing is rotating if possible. The normal operating temperatures for these bearings are 10°F to 200°F in a clean environment. Higher or lower operating temperatures will require the use of a special lube. Higher ambient temperatures require lube with special features and the bearing races should also be specially heat treated or "normalized" to improve their resistance to warping. Also, special seals, internal clearance and frequent lubrication (possibly daily) may be necessary. A bearing required to operate above 250° F will need to be de-rated in capacity. Load de-rated factors can be provided for elevated temperatures. Special seals, lubricant, internal clearances can also be provided. Other Conditions Determine if a standard cast iron housing and the standard bearing will withstand the operating environment. Thermoplastic, Stainless Steel and Nickel plated housings along with Stainless Steel bearing inserts for wash down applications are also available. Consult PTI for other needs or requirements. P.T.
