The 352222 is identified as a double row tapered roller bearing, but the designation alone is not enough to confirm its dimensions, internal design, or suitability for a particular vehicle or machine. Before ordering, compare the bearing against a manufacturer’s drawing or verified catalog data, then check the application, shaft and housing interfaces, and installation requirements. We recommend confirming the full part number and any suffixes with the supplier rather than relying on a visual match. This guide explains what to review so your specification and fitment decision is based on evidence, not assumptions.

This guide is intended for automotive bearing distributors, maintenance teams, purchasing professionals, and engineers evaluating a 352222 replacement or sourcing opportunity. It is also useful when a buyer has received a part number but lacks a complete drawing or application record. Our aim is to help you identify the information needed for a responsible comparison. It is not a substitute for a vehicle maker’s service information or a confirmed bearing specification.
A double row tapered roller bearing uses two rows of tapered rolling elements and matching raceways. This construction can support radial loads and axial loads, with the load capacity and direction depending on the bearing’s internal arrangement and operating conditions. In automotive and other machinery applications, the bearing works as part of a system that includes the shaft or hub, housing, retention features, lubrication, and sealing. Those interfaces affect fitment and performance as much as the bearing designation does.
The code “352222” is a useful identification starting point, not a complete specification. Designations and suffixes can vary between manufacturers, and a similar-looking bearing may differ in boundary dimensions, internal clearance, precision, cage design, or other details. We therefore advise buyers to verify the source catalog or technical drawing for the exact item being quoted. Where an original bearing is available, record its markings and compare its measurable features with supplier documentation.
Request a technical data sheet or drawing that identifies the bearing’s principal dimensions and construction. At a minimum, confirm the bore, outside diameter, overall width, row arrangement, and any relevant mounting or orientation details. Ask whether the quoted part has a suffix or revision that changes its design or interchangeability. If the bearing is being used as an automotive replacement, compare the supplier’s information with the applicable original-equipment reference.
| Item to verify | Why it matters | What to request or inspect |
|---|---|---|
| Bore, outside diameter, and width | These dimensions determine whether the bearing can fit its mounting space. | Drawing, catalog dimensions, and measured parts where available. |
| Internal design and suffixes | Design differences may affect interchangeability and operating behavior. | Full designation, revision, and manufacturer-specific suffix explanation. |
| Load and operating conditions | Suitability depends on the actual loads, speed, temperature, and duty cycle. | Application data and the supplier’s documented selection basis. |
| Lubrication and sealing arrangement | The bearing must work with the lubrication and protection used in the assembly. | Required lubricant, lubrication method, and any sealing or maintenance details. |
Double row tapered roller bearings are used in applications where a compact arrangement must manage combined radial and axial loading. Whether a 352222 bearing is suitable for a particular automotive assembly depends on the assembly design and the bearing’s verified characteristics. A vehicle name, axle position, or broad application description is not sufficient evidence of interchangeability. Confirm the exact equipment, model year or production range where relevant, and the original part reference.
Start with the forces and movement the bearing must accommodate. Consider load magnitude and direction, rotation speed, shock or vibration, operating temperature, and expected service conditions. Also confirm how the bearing is retained and adjusted, if the assembly uses an adjustment procedure. When any of these details are unknown, ask the equipment maker or a qualified technical supplier before substituting a bearing.

Material and construction options should likewise be confirmed rather than assumed from the part number. Depending on the manufacturer and product, relevant differences can include steel grade, heat treatment, cage material, precision class, and surface or corrosion protection. Do not treat these options as standard features of every 352222 bearing. Request written confirmation for the version included in a quotation.
Record the complete marking from the existing bearing, including letters, suffixes, and manufacturer identification. Compare that information with a current drawing or catalog listing for the proposed replacement. If markings are worn or incomplete, use the equipment documentation and measured dimensions as supporting evidence, not as the sole basis for identification. Ask the supplier to confirm any cross-reference in writing.
Before installation, inspect the shaft, hub, housing, shoulders, and retaining components for wear, damage, corrosion, or contamination. Measure the relevant seats using suitable calibrated equipment and follow the equipment maker’s specified tolerances and fit requirements. For clarity, a measurement record might show a shaft seat of 50.000 mm, a housing bore of 110.000 mm, and an axial clearance of 0.10 mm; these are illustrative values only, not 352222 specifications or recommended acceptance limits. Compare actual results with the approved drawing or service data for the assembly.
Establish the correct bearing orientation and installation sequence from the relevant technical instructions. Use appropriate tools and procedures to avoid transferring installation force through rolling elements or damaging raceways and seals. Keep components clean and protect the bearing from moisture and foreign particles before fitting. If adjustment, preload, or end play is specified, follow the equipment maker’s method and target rather than estimating by feel.
For a purchase comparison, evaluate more than the unit price. Confirm that each quotation refers to the same full designation, dimensions, configuration, and requested quantity. Clarify minimum order quantity, available packaging, production or dispatch lead time, and whether the quote covers standard or customized requirements. These commercial terms can vary with stock, order volume, and specification, so request them directly for your project.
At Tuoda Bearing, we support B2B buyers evaluating automotive and other tapered roller bearing requirements. Share the full part marking, application, drawing or original reference, expected quantity, and any operating details available. We can review the information with you and clarify what should be confirmed before a quotation or order is finalized. This process helps reduce avoidable mismatches without treating an unverified cross-reference as guaranteed fitment.
The 352222 designation identifies a double row tapered roller bearing, but it does not by itself establish the dimensions, internal specification, or fitment for your application. To make a sound selection, verify the exact product data, match the bearing to the duty, and inspect the shaft, housing, and installation requirements against approved technical information. For your next step, prepare the complete part marking, application reference, available measurements, and order quantity. Send these details to Tuoda Bearing for a B2B specification review and quotation discussion.
