Snap Ring Groove Ball Bearings
TFL supplies snap ring groove ball bearings for applications where the bearing must be located axially in the housing without a complex shoulder, cover plate, or extra retaining structure. This product list covers metric chrome steel deep groove ball bearings with snap ring grooves or fitted snap rings, including common 60, 62, 63, and selected larger series. Buyers can compare bore diameter, outside diameter, width, snap ring outside diameter, snap ring width, open, sealed, or shielded construction, clearance, tolerance, cage material, lubrication, load rating, and maximum speed. Typical applications include gearboxes, electric motors, pumps, conveyors, agricultural equipment, material handling systems, and machinery requiring compact axial location. TFL can help source standard or custom snap ring bearing options and coordinate inspection and shipment.

Snap Ring Groove Ball Bearing Selection Guide
This page provides high-quality drop-in alternatives for deep groove ball bearings featuring an outer ring snap ring groove (N) or a fitted snap ring (NR). As a specialized sourcing partner, we help you navigate our product list to compare exact bearing dimensions, snap ring thicknesses, seal configurations, clearance, tolerance classes, and dynamic load ratings. For OEM replacements, always confirm whether your application requires the groove only, a pre-fitted snap ring, specific closures (Z/RS), or custom grease fills.
What Is a Snap Ring Ball Bearing and Why Use It?
A snap ring bearing is a standardized deep groove ball bearing manufactured with a precise groove on the outer ring, allowing a steel snap ring (circlip) to locate the bearing axially inside the housing. This intelligent design helps engineers simplify mounting in tight spaces where machining internal housing shoulders, retaining plates, or threaded locknuts is impractical.
By eliminating the need for complex internal housing geometry, snap ring bearings significantly reduce machining costs and assembly time. However, while the snap ring perfectly handles axial positioning, the complete housing design, shaft fits, and the snap ring’s shear strength must still be verified against your actual continuous axial and radial load conditions.
Product Range and Sourcing Options
Our extensive product list contains 784 metric configurations, spanning open, metal-shielded, and rubber-sealed designs. Common industrial designations include N, NR, ZN, ZNR, 2ZNR, 2RSNR, and 2RS1NR styles. These feature premium 52100 chrome steel rings and balls, available in CN (Normal), C3, or C4 radial internal clearances to suit varying operating temperatures.
| Selection Item | Options in This Product List | What to Confirm for Your Application |
|---|---|---|
| Locating feature | Snap ring groove (N) or snap ring fitted (NR) | Whether the application needs the bare groove or a factory-supplied spring steel snap ring |
| Common suffixes | N, NR, ZN, ZNR, 2ZNR, 2RSNR | Confirm the exact alphanumeric suffix from the old bearing, manual, or technical drawing |
| Seal type | Open, shielded (Z), or sealed (RS/2RS) | Protection against dust/moisture, grease retention, seal friction limits, and maximum operating speeds |
| Internal clearance | CN, C3, C4, and selected special options | Shaft press fits, expected thermal expansion, operating speeds, and required running clearance |
| Tolerance class | P0 / ABEC 1 and selected P6 / ABEC 3 options | Maximum speed limits, vibration/noise restrictions, runout limits, and precision requirements |
| Snap ring dimensions | Snap ring outside diameter and width listed by model | Ensure the housing groove and axial locating space precisely match the snap ring dimensions |
Nomenclature Guide: How to Read Snap Ring Suffixes
Suffixes are critical when selecting or cross-referencing a ball bearing with a snap ring. In standard nomenclature, N indicates an outer ring snap ring groove only, while NR indicates the groove comes with the snap ring fitted. Suffixes like Z, 2Z, RS, 2RS, and RSH describe the shielded or sealed environmental protection.
For example, 6204 NR, 6204-2ZNR, and 6204-2RS1NR all share the same basic ISO 6204 boundary dimensions (20x47x14mm), but they differ entirely in closure types and lubrication retention. Always retain the complete designation when requesting a cross-reference quotation to ensure a flawless fit.
Available Snap Ring Bearing Models
Representative equivalent models include 6203 NR, 6204 NR, 6204-2ZNR, 6204-2RS1NR, 6205-2RSNR, 6304 NR, and 6024 NR. The current supply list covers universally common 60, 62, and 63 series models, with bore sizes ranging from compact 10 mm up to selected large-diameter heavy-duty sizes.
Note that some models are supplied ready-to-mount with the snap ring fitted, while others may identify the groove configuration only. Meticulously check the listed snap ring outside diameter, snap ring width (thickness), seal type, clearance, and tolerance before confirming an order.
Typical Industrial Applications
Snap ring groove ball bearings are standard components in automotive gearboxes, electric motors, industrial pumps, HVAC fans, conveyors, agricultural transmissions, power tools, speed reducers, and material handling systems where compact, cost-effective axial positioning is mandatory.
They are the go-to choice when the housing design demands a simplified locating method, yet the system still relies on the robust speed capabilities and radial load capacities of a single-row deep groove ball bearing.
Engineering Warning: Mind the Axial Thrust Limits of Snap Rings
Do not select a replacement by bore size alone, and never assume the snap ring can handle infinite thrust. While a deep groove ball bearing can support significant axial loads, the maximum axial thrust in an NR configuration is often limited by the shear strength of the snap ring itself and the yield strength of the housing groove. For applications with heavy, continuous axial shock loads, verify the load limits before approving a replacement.
Need a Ball Bearing with a Snap Ring?
Send us the complete bearing designation, precise dimensions, snap ring details, housing drawings, seal preferences, operating speeds, load conditions, quantity, or sample photos. Our team will rapidly review and quote the most suitable snap ring groove ball bearing equivalents for your project.
How to Choose from Our Product List
Begin with the original bearing part number or use calipers to accurately measure the bore diameter, outside diameter, width, snap ring outer diameter, and snap ring groove width. Next, compare the closure type (open/shielded/sealed), confirm the internal clearance, cage material, dynamic load ratings, and lubrication type.
If you are replacing a bearing marked with SKF-style suffixes such as NR, ZNR, 2ZNR, or 2RSNR, send our technical team the complete alphanumeric string, clear photos, housing drawings, operating speeds, load conditions, and required quantities. TFL will meticulously cross-reference these to propose fully compatible, high-quality alternative options for your engineering approval.
