> ## Technical Glossary — Bearing Designation Codes

Understanding bearing part numbers helps engineers and buyers find the
right product quickly.

**Series numbers (first 2 digits after type prefix):**
- 60xx: Light narrow series — smallest OD for a given bore
- 62xx: Light series — most common, balanced load and speed
- 63xx: Heavy series — larger OD, higher load capacity
- 67xx: Extra-thin series — smallest OD and width
- 68xx: Thin series — compact, for tight housings
- 69xx: Extra-thin series — very small OD, used in bicycles and robotics

**Bore codes (last 2 digits, for 04 and above, multiply by 5):**
- 00 = 10 mm | 01 = 12 mm | 02 = 15 mm | 03 = 17 mm | 04 = 20 mm
- 05 = 25 mm | 06 = 30 mm | 07 = 35 mm | 08 = 40 mm | 09 = 45 mm
- 10 = 50 mm | 12 = 60 mm

**Seal / shield codes:**
- Open (no suffix): No seal, requires external lubrication
- ZZ: Metal shield both sides — low friction, high speed, dry environments
- 2RS / 2RSH: Rubber seal both sides — better moisture protection,
  slightly lower max speed. 2RSH has lighter contact pressure (less
  friction) than classic 2RS
- 2RZ: Non-contact rubber seal — very low friction, high speed

**Clearance codes:**
- CN (no suffix): Normal clearance — standard for most applications
- C3: Greater than normal — for applications with heat, press-fit
  mounting, or dissimilar housing/shaft materials
- C4: Greater than C3 — for extreme heat (engines, furnace drives)

**Precision class codes:**
- P0 (no suffix): Normal precision — standard for most applications
- P6: Better than P0 — for moderate precision requirements
- P5: High precision (ISO 492) — for machine tools, medical, precision
  drives. Quieter and lower vibration than P0 or P6
- P4: Very high precision — spindle bearings

**Stainless steel prefix:**
- SS: All rings and balls from AISI 440C stainless — corrosion resistant

**Manufacturer codes used at Kugellager24.ch:**
- SKF: SKF Group, Sweden — premium global brand
- FAG: FAG (Schaeffler Group), Germany — premium global brand
- NBR: Quality bearing manufacturer, precision variants
- EBS: Quality European bearing supplier — excellent price/performance
- SON: Economy quality for standard maintenance and repair
- NEU: New quality bearings from selected manufacturers
- NTN, IKO, INA: Japanese and European specialty bearing manufacturers


## Frequently Asked Questions

**Q: Where does Kugellager24.ch deliver?**
A: Across the entire Swiss Confederation. Delivery time 1–3 working days
from our warehouse in Widnau, Canton St. Gallen.

**Q: Do you offer volume / B2B pricing?**
A: Yes. Volume discounts apply from 10 units. Businesses can register
for a dedicated B2B account with individually agreed tiered pricing.
Register at: https://kugellager24.ch/b2b-kundenregistrierung/

**Q: Can you source bearings not listed in the shop?**
A: Yes. Kugellager24.ch is not tied to a specific manufacturer and
can source virtually any standard or special bearing on request.
Contact: info@kugellager24.ch

**Q: What does 2RS mean on a bearing?**
A: 2RS means the bearing has a rubber seal on both sides. It protects
the internal grease from contamination and is maintenance-free under
normal operating conditions.

**Q: What does C3 mean?**
A: C3 designates a radial internal clearance greater than the CN normal
class. It is recommended when the bearing will run warm, is mounted with
a press fit, or when the shaft and housing are made of different materials.

**Q: What is the difference between ZZ and 2RS?**
A: ZZ = metal shield (low friction, higher max speed, less water
protection). 2RS = rubber seal (better protection against moisture and
fine dust, slightly lower max speed). For dry environments choose ZZ;
for wet or dusty environments choose 2RS.

**Q: What does stainless steel (SS) mean for bearings?**
A: SS bearings are manufactured from AISI 440C stainless steel. They
resist corrosion from water, cleaning agents, and mild chemicals.
Required in food processing, medical, marine, and outdoor applications.

**Q: What is P5 precision class?**
A: P5 is a precision manufacturing class defined in ISO 492. It means
tighter dimensional tolerances than the standard P0 class, resulting in
quieter running, lower vibration, and better accuracy. Used in machine
tools, medical devices, and servo drives.

**Q: How do I read a bearing part number?**
A: Example — 6203 2RS C3:
6 = deep groove ball bearing
2 = light series (62xx)
03 = 17 mm bore (03 × 5 = 15? No: bore codes 00–03 are special:
00=10mm, 01=12mm, 02=15mm, 03=17mm)
2RS = rubber seal both sides
C3 = increased radial clearance
Full spec: 17 mm bore, 40 mm OD, 12 mm wide, rubber sealed, C3 clearance.
