F688zz flange bearing 8mm ID flanged bearing dimensions 8x16x5mm

F688zz flange bearing 8mm ID flanged bearing dimensions 8x16x5mm

F688zz flange bearing is a flanged ball bearing made of  stainless steel in which the bearing is metal shield from both sides It has an 8mm ID flanged bearing

• F688ZZ flange bearing 8x16x5mm is a compact miniature flanged ball bearing designed for smooth, low-friction rotation in tight spaces.
• This F688ZZ flanged bearing 8mm ID includes a built-in flange to help with positioning and retention in housings and wheel assemblies, making installation more stable and convenient.
• Made from stainless steel and double metal shielded (ZZ), the bearing helps protect against dust and small debris while supporting reliable high-speed operation.
• The shielded design also helps retain lubrication and can be removed for cleaning and re-lubrication when required.

 Specifications

• Type: Miniature Flanged Ball Bearing (F688ZZ)
• Inner Diameter (ID): 8 mm
• Outer Diameter (OD): 16 mm
• Width: 5 mm
• Flange Diameter: ~18 mm (approx.)
• Material: Stainless steel
• Shield Type: Double metal shields (ZZ)

Features

• 8mm Inner Diameter: Designed for shafts with an 8mm diameter.
• Built-In Flange: Helps position the bearing securely and prevents unwanted axial movement in compatible assemblies.
• Double Metal Shield (ZZ): Protects the internal balls and lubricant from dust and small particles.
• Compact 8×16×5mm Size: Suitable for miniature mechanisms and space-limited applications.
• Smooth Rotation: Deep-groove design provides low-friction and stable rotational movement.
• Stainless Steel Construction: Offers good durability, strength, and resistance to everyday wear.
• High-Speed Capability: Suitable for compact rotating mechanisms requiring smooth operation.
• Low Maintenance: Metal shields help retain lubrication and reduce frequent servicing.

Advantages

• Easy Mounting: The integrated flange simplifies positioning and alignment during installation.
• Prevents Bearing Displacement: Flange helps keep the bearing properly seated in the housing.
• Reduced Friction: Improves rotational efficiency and helps reduce wear on moving components.
• Better Dust Protection: Double metal shields provide additional protection compared with open bearings.
• Long Service Life: Shielded construction helps retain lubricant and protect internal components.
• Space-Saving Design: Compact dimensions make it ideal for small machines and precision assemblies.

Applications

• Small electric motors (appliances, toys, electronics)
• RC vehicles (wheels, axles, moving parts)
• Skateboards & rollerblades (wheel assemblies; flange aids retention)
• 3D printers (carriage, guide rails, lead screws)
• Small machinery & compact devices
• Robotics (joints, actuators)
• Instrumentation & measurement devices
• Model making (miniature rotating parts)
• Bicycles (select components like pedals/hubs, depending on design)
• Medical equipment (small precision instruments)

Package Includs

•  1 piece of F688ZZ bearing.
