Insert bearings are single-row ball bearings with double seal on both sides. The outer ring has a spherical surface and can therefore tilt in the housing to compensate any misalignments between the shaft and the housing. The inner ring is wider than the outer ring and is mounted to the shaft using an eccentric adapter ring or screws. The bearings are filled with a high-quality plastic lubricant, whose properties ensure reliable lubrication, usually throughout the life of the bearing. If necessary, the bearings can be additionally lubricated using a lubrication head located on the housing.

Insert bearings are suitable for short shaft arrangements and for arrangements with small thermal dilatations, which are compensated by the axial clearance in the bearings or by the pliancy of the structure on which the bearing housings are mounted. The maximum operating temperature is 100°C and the minimum operating temperature is -30°C.

UD Design

The UD design insert bearings have the outer and inner ring of equal width.

Boundary dimensions
The boundary dimensions of insert bearings and eccentric adapter rings comply with the ISO 9628 international standard.

Designation

The designation of insert bearings with the basic design is given in the dimension tables.

Cages
Insert bearings have cages pressed from sheet steel, which are not designated.
Precision

Insert bearings are normally manufactured with normal precision grade P0 (the P0 mark is not designated). For special bearing arrangements, bearings are manufactured with higher precision grade P6 and P5. The supply of such bearings needs to be negotiated in advance. Insert bearings have a uniform bore diameter tolerance – H6. This tolerance ensures a movable arrangement in each case when machining a shaft in the tolerance zone h. As a rule, it is sufficient to manufacture the shaft from drawn steel produced in tolerance h8 to h11. For higher loads and higher speeds, it is necessary to manufacture the shaft in tolerance h6 or h7.

Radial Clearance
Insert bearings have the C3 radial clearance, which is not designated and whose range corresponds to the range of radial clearances of single-row ball bearings of the same dimensions. The supply of bearings with a different range of radial clearance needs to be negotiated in advance.
Limiting Speed

The limiting speed that the insert bearings can achieve depends primarily on the arrangement on the shaft. The following table shows the limiting speeds for the various shaft diameter tolerances.

Minimum Load
Insert bearings must be subjected to a certain minimum load to ensure reliable bearing function. The minimum load is 1% of the basic dynamic bearing capacity
Radial and Static Equivalent Dynamic Load

Radial Equivalent Dynamic Load
The equivalent dynamic load of insert bearings is determined in the same way as for standard ball bearings:

Radial Equivalent Static Load
The following applies to the static load of insert bearings:
