Structure characteristics and model representation of bearing with seat

First, the structural characteristics of the bearing with seat:

1. A bearing unit composed of a bearing core and a bearing housing. The outer diameter of the outer ring of most bearing cores is an outer spherical surface, which is matched with the bearing seat with a spherical inner hole;

2. Diverse structural forms, good versatility and interchangeability;

3. With outstanding self-alignment and sealing performance, it can work in harsh environments;

4. Easy to use and install.

2. Bearings with seats-bearing core structure, model and size representation method:

1. UC bearing core structure, model series and size representation method:

Structural features: Both ends of the inner ring of the bearing protrude, with set screws.

Model series: UC2xx, UC3xx, UCXxx. Inch system such as UC201-12.

Dimensional calculation: Metric and general calculation methods are the same. The inch size is hexadecimal. For example, the inner diameter of UC201-12 is: 12 / 16X 25.4 = 19.05mm.

2. UK bearing core structure, model series and size representation method:

Structural features: the inner ring has flat ends at both ends, and the inner hole is tapered. It needs to be used with adapter sleeve during installation.

Model series: UK2xx, UK3xx, UKXxx.

Dimensional calculation: The calculation method for metric and general types is the same.

Adapter sleeve selection: If UK210 bearing core is used with H2310 adapter sleeve.

3. B bearing core structure, model series and size representation method:

Structural features: The bearing inner ring has a flat head on one end and a protruding end on the other, with set screws.

Model series: metric Bx; imperial: Bx-x or Bx-xx.

Dimension calculation: The metric size calculation method is the same as the general class. The inner diameter of the inch system such as B6-18 is: 18 / 16X25.4 = 28.575mm.

4. CS bearing core structure, model series and size representation method:

Structural characteristics: The flat ends of the inner ring of the bearing are sealed with a rubber cover.

Model series: CS2xx (ASAHI) = SC2xx (JIB).

Dimension calculation: The metric size calculation method is the same as the general class.

5. KH bearing core structure, model series and size representation method:

Structural features: The bearing inner ring has a flat head at one end and a protruding end at one end, with an eccentric ring.

Model series: Metric KH2xx; Inch: KH2xx-x or KH2xx-XX.

Dimension calculation: The metric size calculation method is the same as the general class. The inner diameter of the inch system such as KH206-18 is: 18 / 16X25.4 = 28.575mm.

6. UG bearing core structure, model series and size representation method:

Structural features: The inner ring of the bearing protrudes at both ends, with an eccentric ring ER.

Model series: UG2xx + ER, UG3xx + ER.

Dimension calculation: The metric size calculation method is the same as the general class.

FL: Cast diamond seat. The series are FL2xx, FL3xx, FLXxx.

FC: Cast boss round seat. Series are FC2xx, FC3xx, FCXxx.

C: Cast ring seat. The series are C2xx, C3xx, CXxx.

FK: Cast hanging seat. The series are FK2xx, FK3xx, FKXxx.

T: Cast slider base. Series are T2xx, T3xx, TXxx.

Note:
① The outer diameter samples of UC201, UC202, UC203, UC204 are equipped with the same bearing seat (if P204 is used);
② The metric and inch bearing cores are equipped with the same bearing seat. For example, UC207 and UC207-20 are equipped with the same P207.
