NSK bearing parts structure
(1) the raceway raceway.
Rolling bearing surface load part, used as a rolling body rolling track.
(2). Straight raceway straight raceway
On the bus the direction perpendicular to the rolling plane for the linear raceway.
(3). Crowned raceway crowned raceway
In the raceway convex curve was continuous in the direction perpendicular to the rolling plane basic cylindrical or conical, in order to prevent the stress concentration produced roller and raceway contact points.
(4). Spherical raceway spherical raceway
Raceway as a part of the surface of the ball.
(5) the channel raceway groove.
Ball bearing raceway groove - shaped, usually an arc shaped section, the radius slightly larger than the ball radius.
(6). (Gou) shoulder (groove) shoulder
(rolling) road side ditch.
(7) retaining side rib.
Process for rolling narrow shoulder parallel road surface and rolling direction. For supporting and guiding the rolling body and to keep it in the bearing.
(8). Guide cage surface cage riding land
The cylindrical surface of the bearing rings and washers, to guide the holder in the radial.
(9). Ring (washer) end ring (washer) face
Perpendicular to the ring (washer) axis line ring (washer) surface.
(10). The inner hole of the bearing bearing bore
Internal hole rolling bearing inner ring or the shaft ring.
(11). The cylindrical bore cylindrical bore
Bearings and bearing components within the hole, the bus was basically a straight line and with the bearing axis line or lines parallel to axis of bearing parts.
(12) the conical inner hole of tapered bore.
Bearings and bearing components within the hole, the bus was basically a straight line and with the bearing axis line or axis line intersects the bearing parts.
(13). The bearing outer surface bearing outside surface
The outer surface of the outer ring of the rolling bearing or seat.
(14). The ring (washer) chamfering ring (washer) chamfer
The ferrule end face and the outer surface of a hole or ring (washer) connected in the bearing surface.
(15). The more the process tank grinding undercut
The opening in the blocking edge or flange root bearing ring and bearing washers for ease of grinding groove or grooves.
(16). The sealing surface (contact) sealing (conract) surface
With the sliding contact surface sealing ring.
(17). The sealing ring groove (shield) seal (shield) groove
Used to maintain the bearing ring groove (shield).
(18). The snap ring groove of snap ring groove
In order to keep the snap ring groove.
(19). The lubrication groove lubrication groove
The groove is used for conveying lubricant in the bearing parts.
(20) lubrication hole lubrication hole.
In the bearing components, for delivering lubricant into the hole on the rolling body.
