6001 2RS NR ZEN 12x28x8 mm Deep Groove Ball Bearing

Applications

The 6001 2RS NR ZEN bearing is a precision-engineered deep groove ball bearing designed for compact, high-reliability units in industrial settings. With a bore of 12 mm, an outer diameter of 28 mm, and a width of 8 mm, it is ideally suited for use in bearing housings or as part of a bearing unit in motors, gearbox assemblies, conveyors, and other machinery. The dual-side rubber seals (2RS) offer excellent protection against dust and moisture, while the “NR” designation indicates a snap-ring groove in the outer ring, enabling secure fixation within an obudowa łożyskowa without additional retaining hardware. This makes the bearing particularly valuable for applications demanding minimal maintenance and long service life with limited installation space.

Key Advantages & Features

• High durability: The robust steel construction combined with full sealing reduces contamination entry and supports long operational life in challenging environments.

• Sealed on both sides (2RS): This sealing configuration ensures enhanced protection for the internal rolling elements, ideal for industrial applications where dust, debris, or splash may occur.

• Snap-ring groove (NR): Simplifies installation in housings or units by offering integrated positional fixation—reducing assembly time and improving reliability.

• Standardized dimensions (12x28x8 mm): A widely used format in industrial machinery, which simplifies procurement, replacement and stocking practices.

• Compact series design: As a member of the 6000-series deep groove bearings, it offers a balanced combination of load capability and space efficiency, making it suitable for aplikacje przemysłowe with restricted envelope.

Why Choose This Bearing for Industrial Use?

In B2B procurement for industrial equipment, choosing the right bearing is critical for uptime, efficiency and maintenance costs. The 6001 2RS NR ZEN bearing offers all the standard advantages of a deep groove ball bearing—low friction, ability to handle radial and moderate axial loads—while also providing enhanced features such as snap-ring fixation and dual sealing. This translates into fewer accessories needed during assembly, reduced risk of misalignment in the housing, and less downtime due to contamination or seal failure. For engineers designing bearing units or obudowa łożyskowa assemblies in compact machines or conveyor drives, this bearing is a cost-effective way to maintain reliability and service continuity.

FAQ - Frequently Asked Questions

Q1: What does the designation “2RS NR” indicate?
A1: “2RS” signifies rubber seals on both sides of the bearing to prevent ingress of dust and moisture. “NR” indicates the presence of a snap-ring groove in the outer ring, allowing secure installation in a housing or bearing unit without additional retaining rings.

Q2: Are the dimensions 12x28x8 mm exact and interchangeable with other 6001 bearings?
A2: Yes—the 6001 series bearing with dimensions 12 mm (inner) x 28 mm (outer) x 8 mm (width) follows standard sizing. However, when replacing an existing unit, ensure that any snap-ring groove, sealing type, and clearance class match your application requirements.

Q3: What kind of applications is this bearing best suited for?
A3: This bearing is ideal for compact industrial machines, motor shafts, gearboxes, conveyor rollers, bearing housings and bearing units where space is limited, reliable sealing is required and a snap-ring fixation eases mounting.

Q4: What are the benefits in terms of maintenance and service life?
A4: With sealed protection (2RS) and secure fixation (NR), the bearing reduces exposure to contaminants and avoids additional mounting accessories. This leads to fewer maintenance interventions, longer service intervals and better uptime in industrial-grade equipment.

Q5: Can this bearing be used in a bearing housing (obudowa łożyskowa) or bearing unit (jednostka łożyskowa)?
A5: Yes. Its standard size and snap-ring groove make it well-suited for installation in bearing housings or as part of a bearing unit assembly, enabling engineers to integrate it directly into modular machine sub-assemblies.
