Metal Shielded Flange Ball Bearings 6000 6001 6002 6003 6004 6005 6008 6009 6010

Match the inner diameter (d) of the bearing to your shaft diameter. For example, if your shaft is 17 mm, select F6003-ZZ (17×35×10 mm). Then confirm the outer diameter (D) fits your housing bore and the width (B) clears your housing depth. All three dimensions are listed in each variant name as d×D×B.

ZZ indicates double metal shields — one pressed-steel shield on each face of the bearing. The shields retain the factory grease and block coarse particles. Unlike rubber seals (2RS), ZZ shields are non-contact, which means slightly lower friction but less protection against fine dust or liquid ingress. They are well-suited for dry or lightly contaminated workshop environments.

Yes, but with limits. Deep groove ball bearings support moderate axial loads in both directions alongside their primary radial load capacity. They are not designed as dedicated thrust bearings. For applications where axial load is the dominant force, a thrust bearing or angular contact bearing would be more appropriate.

Standard steel construction provides adequate protection in dry indoor environments. For outdoor, humid, or washdown applications, consider stainless steel or ceramic hybrid bearings instead. The ZZ shields are not rated for full submersion or continuous water exposure.

A flanged bearing has an extended lip (flange) on the outer ring that seats against the housing face. This prevents the bearing from being pushed through the housing bore under axial load, eliminating the need for snap rings or retaining clips in many designs. Standard bearings without a flange require additional hardware to achieve the same axial retention.

No. Each bearing is pre-greased at the factory and sealed by the ZZ shields. Under normal operating conditions — moderate speed, moderate load, ambient temperature — no additional lubrication is needed before installation. Re-greasing is not practical on ZZ-shielded bearings; replace the bearing when wear or noise indicates end of service life.

Order 1 piece for a single-axis replacement or prototype test fit. Choose 3 pieces for a small multi-axis machine (e.g., a 3-axis CNC router needing one bearing per axis). Select 5 pieces when building a conveyor with multiple roller stations or when you want spares on hand for a recurring maintenance schedule. Per-unit cost decreases with larger pack quantities.
