SNR 6001 ZZ Deep Groove Ball Bearing 12x28x8

Double-shielded 6001 ZZ bearing — robust protection for radial & axial use

The SNR 6001 ZZ is a single-row deep groove ball bearing with double metal shields (ZZ), specifically designed to deliver smooth, reliable operation in a wide range of applications. Its key dimensions are 12 mm inner diameter (d), 28 mm outer diameter (D), and 8 mm width (B).

Key Specifications & Performance

• Shielding Type: Metal shields on both sides (“ZZ”) — ideal for environments with dust and debris, while allowing some grease flow.

• Bearing Type: Deep groove ball bearing — handles radial loads and limited axial loads in both directions.

• Load Ratings: For SNR’s 6001ZZ, the dynamic load rating is approx. 5.4 kN and static load rating ~2.39 kN.

• Speed Ratings: Reference speed ~24,000 rpm; mechanical limit speed ~36,000 rpm

• Operating Temperatures: Typically -30 °C to +120 °C.

• Materials & Construction: High-carbon chrome steel raceways; pressed steel cage; shielded on both sides.

Applications

This bearing is well suited for:

• Electric motors and pump shafts

• Precision machinery and robotics

• Gearboxes, reducers

• Fans, blowers, conveyors

• Any assembly requiring a compact, shielded deep groove bearing

Because of its double shielding, the 6001 ZZ reduces the risk of particulate ingress while maintaining low friction — ideal for industrial environments, automated systems, or places with moderate contamination.

FAQ (Frequently Asked Questions)

Q: What does “ZZ” mean in bearing designation?
A: “ZZ” indicates metal shields on both sides, providing protection from dust and debris without sealing the bearing completely.

Q: Can 6001 ZZ handle axial loads?
A: Yes — though primarily radial, deep groove bearings like 6001 ZZ can accept moderate axial (thrust) loads in both directions.

Q: How is 6001 ZZ different from 6001 2RS?
A: 6001 2RS has rubber seals (better for sealing fluids) but slightly higher friction; 6001 ZZ uses metal shields, giving lower friction and good protection against dry contaminants.

Q: Is lubrication required before installation?
A: The bearing comes pre-lubricated (factory grease). In demanding or high-temperature applications, periodic relubrication might extend life.

Q: Do you ship internationally and how fast?
A: 📍 Warehouse & Store: Lublin, ul. Smoluchowskiego 1, building 4
🚚 24h shipping - fast and efficient order processing (for orders within serviceable areas)
