352222 Double Row Tapered Roller Bearing Specifications and Replacement Guide
The 352222 double row tapered roller bearing is a bearing designation, not enough by itself to confirm that every product carrying the same number is a direct replacement. Before ordering, compare the original bearing’s dimensions, internal design, clearance or preload, load requirements, lubrication, and mounting arrangement with the replacement supplier’s data. Because catalog details and designation practices can vary, use the bearing marking together with the machine drawing or measured dimensions to verify fit. Tuoda Bearing can review these details with B2B buyers before product confirmation.

Key Takeaways
- Confirm the bore, outside diameter, width, and configuration against a drawing or reliable product data; do not select by designation alone.
- Check operating loads, speed, temperature, lubrication, fits, and installation conditions, not just physical dimensions.
- Send Tuoda Bearing the bearing markings, application details, and clear measurements to help establish a suitable replacement.
Who This Guide Is For
This guide is intended for purchasing teams, maintenance engineers, distributors, and bearing resellers sourcing a 352222 bearing or a potential replacement. It is useful when a bearing is worn, its packaging is unavailable, or a purchasing specification needs to be checked before a repeat order. It also helps buyers prepare the information a manufacturer needs to assess compatibility. It is not a substitute for the equipment maker’s instructions or a verified bearing drawing.
Understanding the 352222 Bearing
Basic concept and function
A double row tapered roller bearing uses two rows of tapered rollers running between matching raceways. This arrangement is designed to support radial loads and axial loads, with the precise load capacity and axial behavior depending on the bearing’s internal geometry and installation. In automotive and other machinery applications, the bearing may be selected where a compact arrangement needs to support combined loads. Confirm the intended mounting position and load direction from the equipment design rather than relying on the name alone.
Types, materials, and configuration details
The designation 352222 identifies a product family, but it does not independently communicate every detail needed for interchange. Depending on the design, relevant differences may include internal clearance or preload, cage construction, seals or shields, precision level, and the arrangement of the two rows. Bearing steel and heat treatment are also important supplier specifications, but buyers should request documented product information rather than assume a particular material grade or process. If the existing bearing has suffixes or markings, record them and share photographs with the supplier.
352222 Specifications to Verify Before Ordering
Start with the principal dimensions: bore diameter, outside diameter, and overall width. Then confirm the bearing’s internal and external configuration, including any locating features, seals, cage details, and mounting components that form part of the assembly. These values should come from a manufacturer drawing, a trustworthy catalog, or careful measurement of the removed bearing. Do not treat dimensions from an unverified online listing as a confirmed specification.
| Specification or condition | What to confirm | Why it matters |
|---|---|---|
| Basic dimensions | Bore, outside diameter, and total width | These determine whether the bearing can fit the shaft and housing. |
| Internal design | Clearance or preload, row arrangement, and any specified tolerances | Differences can affect operating behavior even when external dimensions match. |
| Operating conditions | Radial and axial loads, speed in RPM, and expected temperature in °C | These help assess whether the proposed bearing is suitable for the application. |
| Lubrication and environment | Grease or oil method, relubrication needs, contamination, and moisture exposure | These conditions influence bearing protection, maintenance, and service life. |
How to Select a Replacement
Step 1: Record the original bearing information
Before removal, photograph the bearing marking, surrounding assembly, and any visible suffixes. Note the equipment model, bearing position, and reason for replacement, such as noise, heat, looseness, or planned maintenance. If the original part is damaged, keep it available for identification, but do not use visibly deformed surfaces as the only measurement reference. Ask the equipment manufacturer for the approved part number where that information is available.
Step 2: Measure and compare the fit
Clean accessible bearing surfaces and use suitable measuring tools for the bore, outside diameter, and width. As a practical inspection method, take measurements at three positions around a dimension where access allows, and record readings in millimeters; a caliper or micrometer with 0.01 mm resolution can support initial comparison. This is a measurement practice, not a tolerance specification for the 352222 bearing. For final fit decisions, use the supplier’s drawing and the machine’s shaft and housing requirements.

Step 3: Match the operating duty
Provide the expected radial and axial loads, operating speed, temperature range in °C, duty cycle, and lubrication method. Include information about shock loads, vibration, contamination, and whether the equipment experiences frequent starts and stops. If exact loads are unknown, share the equipment model and application so the supplier can identify what further engineering data is needed. Avoid choosing a replacement based only on a similar-looking bearing or a matching outside diameter.
Step 4: Confirm installation and system requirements
Check the shaft and housing fits, shoulder dimensions, retention method, and any spacers or seals used in the original installation. A correct bearing can still perform poorly if the fit, alignment, preload, or lubrication is incorrect. Follow the equipment maker’s mounting procedure and use appropriate tools; do not transfer impact through the rolling elements during installation. If the replacement changes the internal design or mounting arrangement, obtain technical approval before fitting it.
Common Replacement Mistakes
- Relying on the part number alone: Confirm dimensions and relevant suffixes because the designation may not capture every construction detail.
- Ignoring internal settings: A dimensional match does not prove that clearance, preload, or row configuration is equivalent.
- Using incomplete measurements: Dirt, wear, or damage can distort readings, so compare measurements with an authoritative drawing whenever possible.
- Overlooking the cause of failure: Contamination, poor lubrication, misalignment, or an unsuitable fit can damage a new bearing as well.
- Assuming service conditions: Confirm load, speed, temperature, and lubrication rather than relying on generic application descriptions.
Pricing, MOQ, and Lead Time: What to Ask
Pricing for a 352222 bearing can depend on the confirmed configuration, material and quality requirements, order quantity, packaging, and delivery destination. Minimum order quantities and production or shipping lead times are supplier- and order-specific, so buyers should request current terms rather than rely on a general estimate. Ask whether the quotation refers to a standard product or a customized specification, and request the applicable drawing or technical data for review. Confirm payment, packing, and shipping terms before placing a purchase order.
Supplier Evaluation Checklist
Before approving a source, check whether the supplier can identify the offered bearing configuration and provide dimensional information for comparison. Ask how product identification, inspection documentation, packaging, and traceability are handled for your order. Clarify whether the supplier can review application details and respond to questions about fit, lubrication, and installation. Any certification or test documentation should be requested specifically and verified for the product and order in question.
