The F6805ZZ is a flanged, thin-section deep groove ball bearing with two metal shields. Its commonly listed basic dimensions are a 25 mm bore, 37 mm bearing outside diameter, and 7 mm width; the flange is typically listed at 39 mm outside diameter. The flange can help locate the bearing axially in a housing, while the shields help limit the entry of contaminants and retain lubricant. Before ordering, confirm the drawing, tolerances, and performance ratings with the supplier, because product details can vary by manufacturer.
This guide is for purchasing teams, design engineers, and distributors evaluating an F6805ZZ for equipment or replacement parts. It explains the designation, the dimensions buyers commonly encounter, and the questions that help establish whether the bearing suits a particular assembly. It is also useful when checking a proposed substitute against an existing part. For automotive applications, the bearing should be assessed against the full operating and safety requirements of the component rather than selected by size alone.
F6805ZZ refers to a flanged deep groove ball bearing in a thin-section form. In common bearing nomenclature, “F” indicates a flange, while “ZZ” commonly indicates metal shields on both sides. Designation systems are not fully uniform across all manufacturers, so buyers should confirm the supplier’s interpretation on the product drawing or specification sheet. The suffix alone does not establish a bearing’s load capacity, internal clearance, lubrication, or allowable speed.
Deep groove raceways and balls are designed to support radial loads and, within the bearing’s limits, axial loads in either direction. The flange is part of the outer ring and can help position the bearing against a housing feature. It may simplify assembly where a shoulder or retaining arrangement is appropriate, but it does not automatically secure the bearing against every direction of movement. The housing design and installation method still need to provide the required retention.
| Specification | Common reference | Buyer check |
|---|---|---|
| Bore diameter | 25 mm | Confirm shaft fit and tolerance requirements. |
| Bearing outside diameter | 37 mm | Check the housing bore and fit. |
| Overall bearing width | 7 mm | Verify the available axial space. |
| Flange outside diameter | Typically 39 mm | Confirm flange geometry and housing clearance on the drawing. |
| Shield configuration | ZZ commonly denotes two shields | Confirm shield construction and lubrication details. |
These values are commonly encountered for F6805ZZ products, but they should be treated as a preliminary reference rather than a complete engineering specification. A drawing should clarify flange thickness and profile, chamfers, dimensional tolerances, and any other features relevant to installation. If the bearing replaces a part from another supplier, compare the actual drawing and not just the part number. A small difference in flange geometry or tolerance can affect fit and assembly.
Bearing steel is a common material choice for this bearing category, but the exact material, heat treatment, and component details should be obtained from the manufacturer. Some suppliers may offer alternative materials or configurations, but availability and suitability need to be confirmed for the requested part. Metal shields are different from contact seals and should not be assumed to provide the same level of protection against moisture or fine contaminants. Ask the supplier to identify the lubricant and any applicable service limitations.
The F6805ZZ may be considered where a compact bearing with a 25 mm bore and flange-based positioning is required. Potential equipment categories include mechanisms, light-duty rotating assemblies, and other designs whose verified load, speed, environment, and fit requirements align with the selected bearing specification. These examples are starting points for evaluation, not a guarantee of suitability. Automotive use requires particular attention to vibration, temperature, contamination, duty cycle, and applicable component requirements.

Before selecting the bearing, determine the direction and magnitude of loads, shaft and housing fits, operating speed, temperature range, and expected exposure to dust or moisture. Check whether the bearing will experience shock loads, frequent starts and stops, or misalignment, since these conditions can affect service life. If axial location depends on the flange, confirm that the surrounding structure supports the bearing as intended. For demanding operating conditions, request a technical review based on the application data.
Record the current part number, measured dimensions, flange profile, shield arrangement, and any drawing reference. Compare these details against the proposed F6805ZZ rather than relying on a similar-looking part. Confirm that the shaft and housing fits meet the design requirement and that the flange clears adjacent components. When replacing an installed bearing, also investigate the reason for the original failure or replacement request.
Request the manufacturer’s rated load and speed information for the exact configuration being quoted. Compare those values with the actual operating conditions and design factors specified by your engineering team. Do not infer performance from the 6805 size series or shield suffix alone. If the application includes elevated temperature, unusual lubrication needs, or contamination exposure, identify those conditions before approving the product.
Ask for the product drawing, dimensional and material specifications, packaging details, and the inspection documents available for the order. State any traceability, sampling, or incoming inspection requirements before purchase, so the supplier can confirm feasibility. For repeat programs, clarify how changes to materials, manufacturing, or configuration will be communicated. These checks help purchasing teams compare offers on a consistent basis.
Pricing for an F6805ZZ can depend on order quantity, selected material and specification, packaging, inspection requirements, and shipping terms. Minimum order quantity and lead time are supplier- and order-dependent, so they should be confirmed in a written quotation rather than assumed from a catalog listing. For an accurate offer, provide the required quantity, destination, target delivery schedule, drawing, and any documentation needs. If the product is for a scheduled production program, discuss forecast volumes and replenishment timing as part of sourcing.
At Tuoda Bearing, we support B2B buyers with product and sourcing discussions for deep groove ball bearings, including requests involving the F6805ZZ designation. We can review the dimensions and application details you provide, then confirm the applicable product specification, available documentation, and order terms. Availability, customization, and delivery timing depend on the confirmed requirements and should be agreed before purchase. Sharing a drawing or existing part reference is a practical way to begin the review.
The F6805ZZ is commonly specified with a 25 mm bore, 37 mm bearing outside diameter, 7 mm width, and a flange typically measuring 39 mm across. Its flange can assist with positioning, and its ZZ shields can help protect the bearing, but neither feature alone confirms that it is right for a particular application. Verify the drawing, fit, load and speed ratings, materials, lubrication, and environmental requirements before approving it as a replacement or production component. To evaluate an F6805ZZ for your project, send Tuoda Bearing your drawing or part reference, application conditions, quantity, and delivery needs for a specification and quotation review.
