Description
As a self-aligning ball bearing, this bearing compensates for misalignment and shaft deflection. The principal dimensions are 85x180x60 mm at a weight of 6.75 kg; the further technical details are listed in the specification table. Two rows of balls run on a common spherical outer raceway: the outer ring imposes no direction on the ball set, so the shaft may take up an inclined position relative to the housing.
The self-aligning ball bearing has two rows of balls in the inner ring and a common, spherically formed raceway in the outer ring. Because the centre of curvature of that raceway lies on the bearing axis, the inner ring unit with both rows of balls can swivel inside the outer ring; the bearing position thereby accommodates misalignment between the pillow blocks and a shaft deflected under load, without the contact pressure building up at an edge in the rolling contact.
That is exactly the application case: long shafts, welded or bolted frames, and constructions whose bearing seats are not bored in one setup — in materials handling, agricultural machinery, ventilation plant and textile machinery. The reverse side of the wide outer raceway is a low conformity between ball and raceway: the contact area stays small, the load rating lies below that of a rigid ball bearing of the same size, and friction in the rolling contact is low.
This design can take axial forces only to a modest extent; where the axial load predominates it belongs at a separate bearing position. It should also be noted that the alignment capability compensates for static misalignment — a misalignment that shifts with every revolution, by contrast, means a constant oscillating movement in the bearing and has to be allowed for in the lubrication design.
Rings and balls are made of through-hardened standard bearing steel. The open form brings no sealing element of its own, so sealing, initial filling and relubrication fall to the surrounding construction; the normal radial clearance is matched to a cylindrical seat with common fits.

Same dimensions means the same bearing type and matching main dimensions (d × D × B). Sealing, cage, internal clearance and execution (e.g. material, precision, grease fill) are encoded in the suffix and may differ — please check before ordering. Equivalent additionally means the same sealing, internal clearance and tolerance class; the cage and other suffix features (e.g. lubrication groove) may differ.
