6003 ZZ KYK 17 x 35 x 10 Deep Groove Ball Bearing

Applications & Industries

The 6003 ZZ KYK 17 x 35 x 10 Deep Groove Ball Bearing is a single-row deep groove ball bearing engineered for a wide spectrum of industrial environments. With its compact dimensions (17 mm inner diameter x 35 mm outer diameter x 10 mm width), it fits perfectly into machine tool spindles, small drive units, electric motors, gearbox assemblies, conveyor systems, and other electromechanical units requiring robust load-bearing performance. Its metal shields on both sides (designation ZZ) offer protection against dust and moderate contamination while enabling high-speed rotation.

In applications where “units of bearing” or “bearing housing” (obudowa łożyskowa) and bearing assemblies are regularly replaced or require maintenance intervals, this bearing serves as a reliable “bearing unit” ready for installation. As part of an industrial purchase from a Global B2B marketplace, this bearing offers excellent compatibility with existing pillow block replacements or bearing housing insert assemblies.

Key Advantages & Value Proposition

• High durability & long service life: Manufactured by KYK to consistently meet industrial standards, this bearing provides high operational reliability even under combined radial and axial loads. The deep groove design ensures smooth rotation and lowers friction, contributing to reduced wear and extended equipment life.

• Versatile for industrial applications: Whether for automotive ancillary drives, manufacturing equipment, or production-line robotics, the 6003 ZZ supports a wide range of uses. The compact size makes it especially suitable for tight installations in bearing housings of smaller machines.

• Ready for B2B procurement: As part of a bearing shop online geared to wholesale and direct industrial supply, this product is well-suited for procurement by maintenance departments, OEMs and spare-parts providers. With a focus on “bearing shop online” and “the best bearing”, this item supports bulk orders, consistent stock, and professional supply chain needs.

• Efficient maintenance & cost-effectiveness: Thanks to the metal shields (ZZ) and pre-lubricated condition (depending on variant), the bearing simplifies maintenance scheduling, reduces downtime, and meets expectations for “bearing direct” supply without frequent interventions.

Technical Specifications

• Model: KYK 6003 ZZ

• Dimensions: 17 mm (bore) x 35 mm (outer diameter) x 10 mm (width)

• Type: Deep groove ball bearing (łożysko kulkowe) with metal shields on both sides (ZZ)

• Suitable for radial and light axial loads in both directions

• Typical speed rating and load data: for example, one supplier lists a dynamic load rating and speed limit consistent with 6000-series bearings.

• Material: Chrome steel (bearing steel) with sheet steel cage and shield (standard for this series)

• Seal type: ZZ (metal shield) - non-contact gap seal, enabling higher speeds compared to rubber sealed types

• Common interchange: Equivalent to many standard 6003-series deep groove bearings used globally, making replacement and sourcing simpler

FAQ

Q1: What does the ‘ZZ’ suffix mean in the 6003 ZZ KYK bearing?
A1: The ‘ZZ’ denotes that the bearing has metal shields on both sides. These shields protect the internal ball/raceway assembly from dust and larger particles while maintaining a non-contact gap for higher speed capability. They differ from rubber seals like 2RS which offer better sealing but lower speed limits.

Q2: Can this bearing handle axial loads or only radial loads?
A2: While this deep groove ball bearing is primarily designed for radial loads, its geometry allows it to accommodate moderate axial loads in both directions. It is frequently used in applications where combined radial and axial forces occur.

Q3: How do I select the correct installation and fit for this bearing in a bearing housing?
A3: For best performance, ensure correct shaft and housing fits are used according to the manufacturer’s recommendation or DIN/ISO standards. Pre-lubrication, correct seating (press fit or glide fit as specified), and alignment of the bearing in the obudowa łożyskowa are key to achieving high durability and low noise operation.

Q4: What are typical replacement intervals or conditions that indicate wear of the bearing?
A4: Indicators include increased vibration, elevated or uneven temperature, audible noise during rotation, or loss of precision. Given the bearing’s high durability, adopting a predictive maintenance approach and checking periodically for lubrication condition, contamination ingress and fit stability will maximize lifespan.

Q5: Is this bearing suitable for high-speed applications?
A5: Yes — the metal-shielded (ZZ) design combined with the compact 17x35x10 ratio supports higher speed operation compared to many rubber-sealed equivalents. Always verify the exact speed rating with your application requirements and ensure adequate lubrication and cooling conditions.
