베어링 Code 구분

베어링에는 형식과 기능에 따른 번호를 부여하는데 각각의 Code 번호가 갖고 있는 뜻 을 알고 있으면 번호를 보는 것만으로 베어링의 형식 기능을 가늠할 수 있습니다. 

1. Bearing type code

Code	Type
0	Double row angular contact ball bearing
1	Self-aligning ball bearing
2	Spherical roller bearing Spherical roller thrust bearing
3	Taper roller bearing
4	Double row deep groove ball bearing
5	Thrust ball bearing
6	Single row deep groove ball bearing
7	Single row angular contact ball bearing
8	Cylindrical roller thrust bearing
C	CARB toroidal roller bearing
N	Cylindrical roller bearing
QJ	Four point contact ball bearing
T	Taper roller bearing according

 

예를 들어 번호가 41852 이라면 이는 베어링 형식이 Double row deep groove ball bearing 임을 뜻 합니다. 

  4 : Bearing 형식을 뜻 함.

  1 : 베어링 폭

  8 : 베어링의 직경

  52 : 끝에 숫자에 5를 곱한 수가 베어링의 내경을 뜻 합니다. 예를 들어 번호가 52라면 

        52x5=Ø260mm

        끝에 숫자가 8 이라면 8x5=Ø40mm 내경을 뜻 합니다. 

2. Bearing Prefixes -1

Prefix	Meaning
GS	Housing washer of a cylindrical roller thrust bearing
K	Cylindrical roller and cage thrust assembly
K-	Inner ring with roller and cage assembly (cone) or outer ring (Cup) of inch-size taper roller bearing belonging to an ABMA standard series
L	Separate inner or outer ring of a separable bearing
R	Inner or outer ring with roller (and cage) assembly of a separable bearing
W	Stainless steel deep groove ball bearing
WS	Shaft washer of a cylindrical roller thrust bearing
ZE	Bearing with Sensor mount feature

Bearing prefixes 는 베어링 번호 앞에 위치합니다. 예를 들어 K6028 이라면 번호를 풀어서 형식을 설명하면 다음과 같습니다. 

• K : Cylindrical roller and cage thrust assembly 
• 6: Single row deep groove ball bearing
• Bearing width : 0
• Bearing diameter : 2
• Bearing bore diameter : 8 (8x5=Ø40mm)

3. Bearing Prefixes -2

Prefix	Meaning
CN	Normal internal clearance, normally only used together with an additional letter that identifies a reduced or displaced clearance range
C1	Bearing internal clearance smaller than C2
C2	Bearing internal clearance smaller normal (CN)
C3	Bearing internal clearance greater than normal (CN)
C4	Bearing internal clearance greater than C3
C5	Bearing internal clearance greater than C4
S0	Bearing rings or washers dimensionally stabilized for use at operating temperatures up to +150 °C
S1	Bearing rings or washers dimensionally stabilized for use at operating temperatures up to +200 °C
S3	Bearing rings or washers dimensionally stabilized for use at operating temperatures up to +250 °C
S4	Bearing rings or washers dimensionally stabilized for use at operating temperatures up to +300 °C
S5	Bearing rings or washers dimensionally stabilized for use at operating temperatures up to +350 °C
W	Without annular groove and lubrication holes in outer ring
W33	Annular grove and three lubrication holes in the outer ring
Z	Shield of pressed sheet steel on one side of the bearing
2Z	Shields of pressed sheet steel on both sides of the bearing

Prefixes-2는 베어링 번호 가장 뒤에 위치합니다. 예를 들어 베어링 번호가 23022-S3 이라면

S3 : Bearing rings or washers dimensionally stabilized for use at operating temperature up to 250°C (250까지 사용가능한 와셔, 베어링 링)

 

내용정리

베어링 번호를 통해 베어링의 형식과, 폭, 직경, 내경의 정보와 부가적인 옵션 사항들이 어떠한 것이 들어 있는지를 확인하기 위해서는 Bearing Code 와 Prefix 의 의미를 알고 있어야 한다는 것을 기억해야겠습니다.
