ZKLN 1747 ZZ INA 17x47x25 - Angular Contact Ball Bearing 17x47x25 mm

Applications

The ZKLN 1747 ZZ INA 17x47x25 is a high-precision angular contact ball bearing (often described as thrust/axial angular contact bearing) designed for demanding industrial applications where combined axial and radial loads, as well as high rigidity, are required. With inner diameter 17 mm, outer diameter 47 mm and width 25 mm, the unit finds use in bearing housings and bearing units in machine tools, screw drives, automation equipment, linear motion systems, and other assemblies requiring “bearing unit” level performance. The designation “ZZ” implies metal shields on both sides, improving protection in harsh environments. This bearing suits professional B2B use where high durability, longevity and reliable performance are key.

Key Benefits

• High durability: Engineered from precision materials and manufacturing processes, this bearing offers extended service life under industrial conditions.

• Angular contact design: Built to handle significant axial and radial loads through the contact angle (e.g., 60°) which enhances load‐carrying capacity compared to standard “ball bearing”.

• Compact unit size: 17x47x25 mm is an efficient specification that supports integration into compact bearing housings or bearing units where space is constrained.

• Bearing unit readiness: Ideal as a “unit bearing” component within a mounting arrangement, supporting industrial supply chains and equipment manufacturers who require standardized components.

• Support for industrial applications: Whether in gearboxes, linear drives, CNC machines, or other automation systems, this bearing meets the expectations for “industrial applications” where downtime must be minimized and “high durability” is essential.

Technical Specifications

• Type: Angular contact ball bearing (axial-radial) - single or double direction depending on variant.

• Dimensions: Bore d = 17 mm, Outer diameter D = 47 mm, Width B = 25 mm.

• Basic dynamic axial load rating ~ 18,900 N; static axial ~ 31,500 N (example spec).

• Contact angle: ~ 60° — enabling combined load support and rigidity.

• Seal/shield: ZZ (metal shields both sides) for contamination protection and extended reliability.

• Application keywords: angular contact ball bearing, bearing unit, high durability bearing, industrial bearing, bearing housing component.

As a professional B2B component, this bearing excels when used in bearing units or mounting assemblies (bearing housing) where precision and extended service intervals matter. Its design supports installation in bearing housings and manufacturing setups that rely on high reliability and minimal maintenance.

FAQ

Q1: What does the “ZZ” designation in ZKLN 1747 ZZ mean?
A: “ZZ” indicates metal shields on both sides of the bearing, providing protection against dust and contaminants. This enhances the bearing’s suitability for industrial environments and extends maintenance intervals.

Q2: When should one choose an angular contact bearing like ZKLN 1747 instead of a standard radial ball bearing?
A: Choose this model when the application involves significant axial loads (thrust loads) or combined axial and radial loads, or when high rigidity and precision are demanded. Standard radial bearings are less suited for such conditions.

Q3: In what kind of industrial applications is this bearing typically used?
A: Typical uses include screw drives, CNC machine tool spindles, automation systems, linear motion assemblies, bearing housings in production lines, and other settings where a bearing unit must handle both axial forces and radial forces while maintaining high durability.

Q4: Is this bearing considered a “bearing unit” and can it be integrated into a bearing housing?
A: Yes. Due to its format and performance, the bearing is well suited for integration into a bearing housing or as a component of a bearing unit assembly in industrial equipment.

Q5: What are the advantages in procurement and stock for B2B clients?
A: For B2B supply chains, this bearing offers standardized dimensions, high durability, and suitability for industrial applications—making it a smart choice for stock in inventory, ensuring availability, and reducing downtime due to component failure.
