29412E Spherical Roller Thrust Bearing: Dimensions, Specifications, and Selection Guide

The 29412E is a spherical roller thrust bearing intended primarily for applications with heavy axial loads and possible shaft misalignment. Its commonly listed boundary dimensions are a 60 mm bore, 130 mm outside diameter, and 42 mm overall height. Use these dimensions as an initial identification reference, then confirm the drawing, tolerances, load ratings, lubrication requirements, and suffix details against the specific supplier’s catalogue before ordering.

This guide explains what the 29412E designation means, how to check its fit and operating requirements, and what information to provide when requesting a quotation. At Tuoda Bearing, we recommend selecting this bearing from the complete application conditions rather than from the designation alone. That approach helps buyers avoid interchange and performance assumptions that may not hold across manufacturers.

Key takeaways

• The commonly referenced 29412E dimensions are 60 mm bore, 130 mm outside diameter, and 42 mm height.
• It is a thrust bearing for predominantly axial loading; confirm whether the application also imposes radial load.
• Check the full designation, catalogue data, mounting arrangement, lubrication, speed, and operating temperature before purchase.
• Share the equipment drawing and operating conditions with your supplier to verify interchangeability and suitability.

Who this guide is for

This guide is for purchasing teams, maintenance engineers, and design professionals sourcing a 29412E spherical roller thrust bearing. It is also useful when replacing an installed bearing and checking whether a proposed alternative is genuinely compatible. Buyers working with automotive or heavy-vehicle equipment should verify the bearing’s position and load duty in the assembly, since a thrust bearing is not automatically a substitute for a radial or wheel bearing.

What is a 29412E spherical roller thrust bearing?

A spherical roller thrust bearing uses rollers with a curved contact geometry between its raceways. The design is intended to carry substantial axial load while accommodating a degree of angular misalignment between the shaft and housing, within the limits stated by the manufacturer. The 29412E designation identifies a particular size and design family, but the suffix and detailed internal design should be checked in the relevant catalogue.

Typical dimensions and identification

These are commonly published boundary dimensions, not a complete engineering specification. Tolerances, chamfers, internal clearance, cage design, load ratings, limiting speed, and mass can vary by manufacturer or product execution. Ask for the current product drawing and technical data sheet for the exact bearing being offered.

Specifications that matter beyond dimensions

Matching the bore, outside diameter, and height does not by itself establish that two bearings are interchangeable. The application also depends on the bearing’s load capacity, operating speed, lubrication method, temperature, fit, and mounting arrangement. For a rotating assembly, confirm whether the shaft washer, housing washer, and bearing components are installed in the intended orientation.

Load, speed, and operating conditions

Start by identifying the direction and magnitude of the axial load, including whether it is steady, variable, or subject to shock. If the bearing also experiences radial force, provide that information to the supplier; do not assume that the bearing can carry any radial load merely because its rollers are spherical. Share the required operating speed in revolutions per minute (r/min), duty cycle, and any start-stop or impact conditions so the supplier can assess the relevant catalogue limits.

Temperature and lubrication influence bearing performance and service requirements. Specify the expected operating temperature in °C, lubricant type, relubrication interval if known, and whether the assembly is exposed to dust, moisture, or other contaminants. If these conditions are uncertain, provide the equipment details and ask for recommendations rather than selecting a lubricant or speed limit by assumption.

Application matching and material options

29412E bearings may be considered for machinery where a compact arrangement must support axial loading and accommodate limited misalignment. Potential settings include industrial gearboxes, pumps, and other rotating equipment, but suitability depends on the actual load, speed, and mounting design. In automotive and heavy-vehicle powertrain applications, verify the bearing’s intended function and the equipment maker’s requirements before treating it as a replacement part.

Standard bearing steel is a common material option, while other materials or treatments may be offered for specific operating needs. Do not assume that a particular 29412E has a special steel grade, coating, cage material, or heat treatment based on the designation alone. If corrosion resistance, elevated temperature capability, or another special property is required, specify it in the inquiry and request confirmation in the technical documentation.

How to select the right 29412E bearing

Step 1: Confirm the installed bearing and space

Record the full marking on the existing bearing and compare it with the equipment drawing or bill of materials. Measure the available shaft, housing, and axial spaces where appropriate, while following safe maintenance procedures. If the original part is damaged or the marking is unreadable, provide clear photographs and assembly details to your supplier.

Step 2: Describe the operating duty

List the axial and radial loads, speed, operating temperature, lubrication method, and expected duty cycle. Note whether loads reverse, fluctuate, or include shock, and describe any misalignment between shaft and housing. These details allow a technical review that goes beyond a dimensional match.

Step 3: Verify fit and installation requirements

Check shaft and housing tolerances, seating faces, clearance, and installation orientation against the bearing documentation. Confirm any requirements for lubrication access, retaining components, or preload and axial adjustment in the assembly. Installation and adjustment should follow the equipment manufacturer’s procedure or a qualified engineer’s instructions.

Step 4: Compare supplier documentation

Request a drawing, product specification, designation explanation, and applicable inspection or traceability documents. Compare the offered bearing’s dimensions and technical values with the original requirement, rather than relying only on a product title or verbal assurance. For a cross-reference, obtain written confirmation that the proposed item matches the intended application and configuration.

Common purchasing mistakes

• Choosing by dimensions alone: Identical boundary dimensions do not guarantee matching internal design or load ratings.
• Ignoring suffixes: Letters such as “E” can indicate a design variant; confirm the meaning with the specific manufacturer.
• Overlooking radial load: State all load directions and ask for an application review when the bearing sees combined loading.
• Assuming interchangeability: Check fits, tolerances, cage execution, lubrication, and mounting details before approving a substitute.
• Leaving out operating data: A supplier cannot assess speed, temperature, or duty suitability accurately without the relevant conditions.

Pricing, MOQ, and lead time

The price and availability of a 29412E depend on the requested specification, quantity, packaging, and current production or inventory status. Minimum order quantities and lead times are supplier- and order-specific, so buyers should request a current quotation rather than assume fixed terms. For project planning, provide the required quantity, target delivery date, destination, and any packaging or documentation needs at the inquiry stage.

Evaluating a supplier

Ask whether the supplier can confirm the exact designation, provide a dimensioned drawing, and explain any proposed alternative. Clarify what inspection documents and traceability information are available for the quoted item, and ensure that commercial terms are stated clearly. If the bearing is for a critical assembly, share the application data early so technical questions can be resolved before a purchase order is placed.

Tuoda Bearing supports B2B buyers with bearing product information, quotation coordination, and specification review based on the details provided. To request pricing or confirm a 29412E option, send the required quantity, full bearing marking, application, operating speed, loads, temperature, and delivery destination. We can then review the stated requirements and identify what technical information needs confirmation before order placement.

Conclusion

The 29412E is commonly identified by dimensions of 60 × 130 × 42 mm and is designed primarily for axial-load applications where limited misalignment accommodation is useful. These dimensions are a starting point, not a complete selection decision: verify the manufacturer’s drawing, load and speed data, fits, lubrication, and suffix details. The next step is to provide your application conditions and required quantity to Tuoda Bearing for a specification check and quotation.
