product selection guide nicetm ball bearings inc produces a full line of ground semi-ground and unground bearing assemblies to choose the exact bearing you need start with the nicetm line of standard inch-dimension radial angular contact and thrust ball bearings standard series bearings can be customized to include many features that can satisfy the demands of many special applications they are available with special bores modified outer ring shapes extended inner rings locking devices and flanged housings standards can be ordered sealed shielded or open and are offered in ground and semi-ground grades to deliver the most cost effective solution for your application if you are now designing with only abec-1 level or higher bearings chances are there may be a more economical solution to your application a nicetm application engineer can help you determine the exact precision your design requires and show you how to take advantage of the savings selection and special features available in our standard series even when a standard isn t the answer our engineers can deliver an economical modified standard design that is fit for purpose nicetm standard product line class series 1600tm 7500tm ground type retainer radial radial raceways bore o.d faces ground surfaces bore range 3/16 1 5/16 4.76-49.21 1/2 1 1/4 12.70-31.75 1/2 1 1/4 12.70-31.75 semiground radial 7600tm extended inner radial extended er inner metric o.d radial flanged 6900tm extended inner 3000tm retainer radial 5/8 1 15/16 15.86-49.21 raceways o.d faces outer raceways o.d faces 3/8 1 9.53-25.40 3/16 1 4.76-25.40 3/16 2 4.76-50.80 unground full 400tm complement 5000tm radial 500tm radial/thrust 600tm thrust radial none 1/4 2 1/4 6.35-57.15 1/4 1 1/2 6.35-38.10 modified standards and specials all retainer and full types thrust radial/thrust any combination 3/16 2 4.76-50.80 design three basic ball bearing types are illustrated to assist in proper design selection bearings are designed primacarry applied 1 radial carry loads perpendicular to 2 thrust bearingsaxis ofloads bearing rily to parallel to the the the axis of the bearing bore they will also accommodate limited thrust loading or a combination radial and thrust load bore they are not designed to accommodate radial loads bearings are 3 combination radial and thrustapplied thrust designed for simultaneously and radial loads combination assemblies will also carry pure thrust loading however they are not recommended for straight radial loads unless provisions are made to keep the inner rings and outer rings in proper contact with the balls many sizes and types of the three basic designs illustrated are available for selection from this catalog however if you have an unusual application problem nicetm field and factory engineers will be glad to give you the benefit of their specialized training and broad practical experience 4
