3 earings earings have spherical outer races to accommodate up to 1.5 misalignment. Races and balls are made of A vacuum degassed bearing quality steel. all retainers are made of molded, glass fiber reinforced polyamide. Races are hardened, ground and honed for quiet operation, and rade 10 balls are used. Inner races are zone hardened in the ball raceway and seal contact areas. The setscrew end is unhardened to prevent cracking at the setscrew threads. etscrews are located at 120 to minimize inner ring distortion, and have knurled cup point to resist loosening under vibration. eals have a nitrile rubber lip bonded to a steel trash ousings ousings for ub ity bearing units are precision machined from rugged cast iron or high strength ub-alloy castings. ub-alloy is a cast ferrous material this is manufactured in a carefully controlled process to produce properties exceeding the specifications listed below. ub-alloy can be used to replace malleable iron or ductile iron. It is recommended for severe applications where the stronger material is required to withstand heavy loads imposed on the housing. ub-alloy has tensile strength properties in the range 50-65,000 psi, yield strength in the range 32-45,000 psi, and elongation in the range 10-12%. pecific properties of particular housings vary according to the configuration of the housing. ast iron housings meet or exceed the requirements of A 3000 gray iron. Typical tensile strength is 30,000 psi. The nickel-plated bearing housings have an electroplated nickel base, with a finish plating of chrome. Tests conducted at ub ity show that plating of this type will provide excellent durability and optimum performance under normal washdown conditions. guard.. The positive contact, low friction seal rides on the precision ground surface of the inner race. Wide inner race bearings also have steel flingers that rotate with the inner race to provide extra protection. All ball bearings are prelubricated with high quality lithium grease. ub ity bearings have an operating temperature range of -25 F to 225 F. pecial odifications ub ity can furnish modified or special units to suit customer requirements. Typical modifications include: n ousing modifications n Nickel plating of housings in addition to those cataloged n pecial grease types n ust caps n Auxiliary anti-rotation devices Features n ustom bearing units with special housings and/or bearings odified or special units may be subject to increased lead time and minimum production order quantities.

6 ngineering and election Information aximum peed aximum speed limits listed for the ball bearing products described in this catalog should be used as a guide and considered along with other factors affecting bearing operation. oad characteristics, bearing lubrication, and temperature factors all influence bearing operation. It is possible that cataloged speed limits may be exceeded after a complete application analysis is completed by factory engineers. earing ife earing life is commonly referred to in terms of the number of hours of operation at a given speed, that 90% of the bearings in a lot can equal or exceed before the onset of fatigue failure. This is called the -10 life of a bearing. The ball bearing unit load ratings published in this catalog are based upon AFA tandard ection 9, oad Ratings and Fatigue ife Ratings for all earings and are the steady radial loads at which the bearings will endure at various speeds for 500 hours -10 life, or 2,500 hours average life (average life is considered to be 5 times -10 life). earing oads Radial loads and thrust force in combination are the principal load components of bearing applied loads. ub ity ball bearing unit ratings are based upon the radial load capacity of the bearing. For applications where bearings are required to absorb thrust forces in addition to normal radial loads, the following considerations must be made concerning the magnitude of the thrust force. 1. When thrust loads are less than 1/2 of the radial load the equivalent load should be considered the same as the radial load and the selection made based upon the applied radial load. 2. When thrust loads are equal to or greater than 1/2 of the radial load the equivalent load is determined by adding the radial and thrust loads together. The bearing selection is based upon using this total load as the equivalent applied radial load. If thrust loads are equal to or exceed the radial loads, consult the factory. earing election election of the proper ub ity bearing unit for a determined speed and load can be made by referring to the load rating tables. Proper selection is made by finding a bearing having the desired bore size which has a load rating equal to or greater than the radial or equivalent radial load required for the application. ngineering ata earing reaction loads are caused by forces acting on the shaft supported by the bearings. These forces are a result of the weight of the shafting and components mounted on the shafting, bending loads due to belt or chain pull, gear reaction loads, and off center or unbalanced loads. These loads must be combined into a single resultant load of known magnitude and direction for each bearing. Whether the load is applied between bearings on a shaft supported by two bearings or outboard of one of the bearings is important to proper bearing selection. The magnitude and direction of the load for either case may be calculated by taking moments about the other bearing. election xample 1: Radial oad ervice ife xpectancy election elect a mounted bearing pillow block unit to meet the following application requirements: a. haft diameter of 1 inch b. haft speed is 1500 RP. c. Radial load requirement is 850 bs. d. ife requirement is 1000 hours -10 (5000 hours average life) tep 1. From the rating tables on pages -12 and -31, locate the one inch shaft diameter line and follow that line to the right to the 1500 RP column. Note that the radial load capacity for 100 eries bearings and 200 eries bearings (ratings, page -12) is 890 pounds. The radial load capacity for 350 eries bearings (ratings, page -31) is 1230 pounds.

The published radial load capacities are based on an -10 life of 500 hours and must be modified to suit the application requirement of 1000 hours -10 life by using the proper multiplier from the chart below each rating table. alculate the equivalent radial load capacity for 1000 hours -10 life expectancy as follows: For 100 or 200 eries Units 890 bs. radial capacity x hours -10 life factor 707 bs. radial capacity for 1000 hours -10 life For 350 eries: Units 1230 bs. radical capacity x hours -10 life factor 977 bs. radical capacity for 1000 hours -10 life tep 3. The application radial load requirement of 850 pounds is greater than the radial load capacity for 1000 hours -10 life for the 100 or 200 eries bearing units. The radial load capacity of the 350 eries bearing unit is 977 pounds and is greater than the application requirement of 650 pounds. A 350 eries bearing unit is the proper selection. ince a mounted bearing pillow block is required, a 350 eries pillow block with 1 inch bore should be specified. election xample 2: ombination Radial and Thrust oad Requirement elect a ub ity mounted bearing flange block to meet the following conditions: a. haft diameter is 1-3/16. b. A combination load is applied consisting of: Radial load 400 pounds Thrust load is 250 pounds c. haft speed is 500 RP d. The -10 life requirement is 500 hours (2500 hours average life) tep 1. From the load rating tables, -12 and -31, locate the 1-3/16 inch shaft size line and follow this line to the right to the 500 RP column. The radial load capacity for 100 eries (page -12) and 200 eries (page -12) bearing units is 1780 pounds. The radial load capacity for 350 eries (page -31) bearing units is 2330 pounds. tep 2. ince the application -10 life requirement of 500 hours is what the catalog rating charts are based on there s no need to apply further modifying factors. tep 3. ecause the applied thrust load of 250 pounds is more than half of the applied radial load of 400 pounds, these loads must be added together to obtain the equivalent radial load requirement. quivalent Radial oad = 400 bs bs. = 650 bs. tep 4. The equivalent radial load requirement of 650 pounds is less than the catalog radial load capacity for 100 eries, 200 eries, or 350 eries bearing units. The application requirement is for a flange block unit. A choice must be made as to whether a 2-bolt, 3-bolt, or 4-bolt flange is desired. The proper selection can then be made based on the preference for housing material (gray iron, or U-AOY ) and type of shaft locking preference (setscrew or eccentric collar locking) and whether a non-relube or relube type bearing is required.
