FULL OMPLEMENT NEELE EARINGS
Technical features Full complement neele bearings These bearings are available with or without an inner ring from 12 bore size. Stanar complete bearings type NA have an inner ring with convex raceway form. lf extra wie inner rings or rings with lubrication hole are require, they shoul be orere separately for use with the corresponing RNA series. Reference stanars are: ISO 16 - Neele roller bearings Light an meium series imensions an tolerances. Full complement neele bearings have a throughharene outer ring which results in high static an ynamic loa capacities an an ability to withstan overloaing, shocks an vibration. They are particularly suitable for operations involving oscillating motion but may also accept high spee conitions where goo alignment is necessary. This can more easily be achieve using a convex inner ring raceway (inner rings with suffix R6). The retention of the neeles in the outer ring enables the bearing to be installe easily uring assembly. The ifference between the neele bearings with integral en flanges series 00 an the others is explaine in the hapter of the earings with cages. TYPES OF EARINGS Neele roller bearings with inner rings FULL OMPLEMENT EARINGS WITHOUT INNER RING The shaft journal which is use irectly as the inner ring raceway of the bearing shoul have aequate harness an satisfactory surface finish. A harness of 58-64 HR will ensure full loa capacity for the bearing. Lower harness figures will entail a reuction in both static an ynamic capacities as shown in the table of imensions (see Technical Section). In cases of misalignment, a convex inner ring raceway can be machine irectly at the shaft journal position by grining, using a concave profile an inclining the iamon impregnate grining wheel. A convex inner ring raceway calculate to permit misalignment of 1 in 0 oes not affect bearing loa capacity. A larger convex raius is necessary for a greater egree of misalignment but this will reuce the effective bearing loa capacity.

Technical features Full complement neele bearings INNER RINGS lnner rings mae from high quality bearing steel heat treate an through-harene avoi any necessity for heat treatment of the shaft an enable the bearings to operate within their full loa capacity. lnner rings with convex raceway R6 These inner rings without lubrication hole are of the same with as the outer ring an are supplie with series NA complete, types 0, 00, 200 an 00. They can accept a misalignment of 1 in 0 in continuous operation an up to 2 in 0 temporarily, as in the case of suen eflection ue to overloa conitions. The inner an outer rings may be isplace axially from one to the other by up to 5% of the ring with. The esignation of the inner ring separate from the complete neele bearing is I number R6. For example I R6. The esignation of the neele bearings complete of inner ring I R6 is NA number. For example NA. lnner rings with cylinrical raceway ylinrical inner rings of the same bore as those with convex raceway may be supplie on request in the following versions: - with oil hole permitting lubrication through the shaft (I). - wier than corresponing outer ring (IG), to enable a isplacement in position of one ring relative to the other (e.g. expansion of the shaft) or lateral shaft movement. In the latter case, which can occur with or without simultaneous rotation of the shaft, please consult Naella Technical Service. RING TOLERANES lnner an outer rings for full complement stanar neele bearings are manufacture in accorance with the tolerance class of ISO Stanar 492 (class zero accoring to IN 6). loser tolerances, corresponing to classes 6, 5 an 4 may be necessary fopecial high precision applications (symbols P6, P5, P4). See table at the en of the catalogue. RAIALPLAY earings without inner ring The raial play of a bearing without inner ring results from the ifference in iameter beneath the neeles an the size of the shaft. The stanar iameter beneath the neeles for RNA bearings with the recoene shaft tolerances shoul provie suitable raial play for most normal applications. Fopecial applications (high precision, close fits, etc.), we can offer the iameter beneath the neeles selecte as follows: - in the bottom half of the normal tolerance (RNA...

In particular cases where lubrication is provie through the shaft, the inner ring with oil hole may be replace by a lubrication hole at the face of the inner ring. A nominal iameter uner the neeles further reuce may be require for certain precision. Shoul a larger clearance than normal be necessary, the shaft iameter must be controlle nearer to the nominal size than the tolerances h5 or g5 woul normally provie.

Technical features Full complement neele bearings EARING MOUNTING General requirements In general, the mounting of neele roller bearings with or without inner rings, of normal precision, requires the shaft seat or raceway to be machine to quality IT5 or IT6. The housing bore shoul meet quality IT6 or IT7. Other quality requirements fohaft an housings are given on page 13. MOUNTING IMENSIONS It is recoene that neele roller bearings are mounte in their housings with a clearance fit if the loa is stationary relative to the housing, an with a tight transition fit if the loa rotates relative to the housing. Table 2 lists the recoene tolerances for the housing bore an the shaft raceway for bearings without inner rings. Table 3 lists the recoene shaft tolerances for the above two mounting conitions when the bearings are use with inner rings. Other mounting imensions may be require fopecial operating conitions such as: 1. Extremely heavy raial loas 2. Shock loas 3. Temperature graient across bearing 4.
