Angular Contact Ball Bearing Combinations Available: 7944A5TRDUMP3 Bearing

Normally, NSK supplies matched super precision angular contact ball bearings as 2, 3, and 4 row combinations.

The combinations available for the fixed end of spindles are usually 2 rows (DB), 3 rows (DBD), and 4 rows (DBB) sets.
However, in the case of 3 row combinations, since the preload distribution to each bearing is not equal, the optimum preload setting range is very limited, making them unsuitable for high speed applications.
Matched bearings are manufactured as sets, so when they are mounted adjacent to each other, a given preload is automatically obtained.
The variation per pair of matched bearings for bore and outer diameters is adjusted to less than 1/3 of the permissible tolerance.

Features of Each Combination: (7944A5TRDUMP3 Bearing)

7944A5TRDUMP3 Bearing Universal Combination:

NSK supplies universal combination angular contact ball bearings that have the same amount of stand out on both the front and back face. 

This means that when bearings that have the same reference number are combined, they have the specified amount foreach standard preload.

For universal combination bearings, the "V" combination marks on the outer diameter surface of outer ring prevent "direction" mistakes, ensure correct matching when they are mounted, and indicate the direction of the contact angle.
