HJ 2226 EC Angle Ring

HJ 2226 EC is a cylindrical roller bearing angle ring. Its selection starts with the interface it contributes to the mechanism. The separately specified mating members, their seating and the intended contact condition determine how that interface works after assembly. Keep the component designation with its dimensional and condition data when comparing alternatives; a similar nominal size is not enough to establish a replacement.

Component Role and Mating Contact

HJ 2226 EC is an angle ring for a compatible cylindrical roller bearing arrangement. Its contacting face contributes an axial locating interface adjacent to the inner-ring side. The part is not a bearing ring set and does not include rolling elements. Its contact width, radial envelope and edge clearance must agree with the adjacent bearing member and the supporting shoulder.

Axial location is produced by the complete relationship between the angle ring, bearing geometry and shaft support. Confirm the required reaction direction and the bearing form before assigning a locating duty. A loose or unevenly supported face can disturb the intended contact. The angle-ring designation does not establish axial capacity, and a related series number does not prove suitability for an arbitrary cylindrical bearing.

Dimensions That Define the Interfaces

The principal dimensional entries identify System of Measurement: Metric, Bore Dia: 130 mm, Outer Dia: 164.1 mm, and Width: 21 mm. The total width and the width contacting the inner-ring side face serve different purposes. Coordinate bore location, outside clearance and the contact face with the adjacent cylindrical bearing. The axial envelope must leave the intended seating and edge relief rather than merely fit over the shaft.

Interface limits include Bore Dia Tolerance: -0.025mm to 0, Outer Dia Tolerance: -0.025mm to 0, and Width Tolerance: -0.12mm to 0. Use each limit for the dimension named. Component limits do not directly specify a shaft or housing machining tolerance. The required fit also depends on support stiffness, loading and temperature. Check the assembled geometry after seating rather than judging compatibility from one nominal dimension. Retain the signs and units of each limit instead of treating it as a symmetric tolerance.

Backing, Edge Clearance and Assembly

Seat HJ 2226 EC against the intended inner-ring-side interface with adequate, square backing. Check contact-face position and edge relief before assigning axial restraint. The adjacent bearing and shaft shoulder must provide the intended support without trapping the ring on an interfering radius or leaving its face partly unsupported. The relevant interface entries are Width Contacting Inner Ring Side Face: 11 mm and Chamfer Length Radial Direction (Angle Rings)(r3,4)(min.): 3 mm.

After assembly, check seating, alignment, the intended freedom of motion and lubricant access before applying normal duty. Preserve the individual contact and backing relationships when evaluating runout, heating or wear. Do not route mounting force through rolling contacts simply because it is convenient, and do not infer an installation torque, fit class or preload force that has not been specified.

Material Roles and Geometric Condition

The stated component entries are Material: Chrome Steel. This entry describes the ring member and must not be extended to the separately selected rolling elements or cage. Consider the mating surface and actual operating exposure together. The material name does not independently establish heat treatment, contact endurance or environmental qualification of the completed arrangement.

Assess the contact condition using the specified geometry and the required mating surface condition. No unlisted grade or hardness should be assigned to the component. Surface condition and the mating material affect contact stress and wear. Relate these details to alignment, lubricant film and cleanliness without assigning an unlisted material treatment or operating capability.

Ratings and the Operating Arrangement

Evaluate capacity through the complete mating contact system rather than assigning a load limit to this component alone. The working surface must remain correctly supported and aligned, with contact conditions established by the mating design. Load, speed and lubricant film interact in the completed arrangement. The component designation and nominal size cannot replace that operating assessment.

Operating entries identify Temperature Range: -30° to 110 °C. Lubricant selection, delivery and heat removal depend on the complete duty. Provide a route to the working contacts and account for contamination and retention through the surrounding design. Do not assign an enclosure or a replenishment interval from the component designation.

Selecting the Component as Part of a System

The selection of HJ 2226 EC should resolve the cylindrical bearing arrangement, contact face and axial reaction direction. This is the component’s useful engineering context, not a machine-specific approval. Compare the exact designation and interface condition before considering an alternative. Material roles, tolerances and any operating entries must remain connected to the same ordered component rather than borrowed from another member of the arrangement.

For procurement and assembly planning, retain the part specification with the confirmed mating designations and the dimensional requirements of the mechanism. Check support, lubricant access and the intended operating duty as a connected system. The value of this component lies in providing its particular interface correctly; similar nomenclature, a shared series or a matching nominal size cannot establish whole-bearing performance or exact interchangeability.
