IKO TAFI51512 Needle Roller Bearing with Inner Ring, 5 x 15 x 12 mm
Available
The IKO TAFI is a light duty machined type needle roller bearing with an inner ring. This page lists 50 sizes: 5 to 95 mm bore, 15 to 125 mm outside diameter and 12 to 36 mm wide.
Machined type needle roller bearings have a low sectional height and large load ratings. The outer ring is rigid and can be used even in light alloy housings. The TAFI series has a low section height like a shell type bearing and is used for light loads. The inner ring lets the bearing run on a shaft that cannot be heat-treated and ground. The inner ring and the outer ring with cage are separable, with a small relief clearance on both sides of the inner ring raceway to make mounting easier.
For the same series without an inner ring, see the TAF page.

d is the bore, D the outside diameter, C the outer ring width and Fw the roller set bore diameter; C and C0 are the basic dynamic and static load ratings, and speed is the allowable rotational speed.
Selecting the right option
Choose the size with the Outside Diameter and Width (mm) options; the bore is in the model number and in the sizes table.
Bearings with an inner ring suit shafts that cannot be heat-treated and ground. If your shaft is hardened and ground, a type without an inner ring (TAF and RNA, or BR for inch shafts) can be used instead.
The assembled inner ring is shown against each size in the sizes table. The bearing and its inner ring are listed as separate parts, so confirm with AIMS what is supplied if you need both together.
Fitting and use
These bearings are not prepacked with grease, so lubricate them before use. The allowable rotational speed in the tables is for oil lubrication; for grease lubrication use up to 60% of it. Bearings up to 22 mm bore have no oil hole (18 sizes); larger bores have one in the outer ring with an oil groove (32 sizes). The inner ring has no oil hole.
Heat expansion in use, or mounting errors, can shift the inner or outer ring axially so that the rollers do not contact the raceway along their whole length. Keep any axial shift within the allowable value S given for each size in the specifications.
Ask AIMS for the shaft and housing tolerances that suit your application.
