Introduction:

Dimensions

The boundary dimensions of ZYSL thrust ball bearings with flat or sphered housing washers conform to DIN 711:1988 and DIN 715:1987. The dimensions of the bearings with flat housing washers conform to ISO 104:2002.

The values given for the height H1 for bearings with sphered housing washer(s) are valid only for ZYSL bearings with ZYSL washers.

Tolerances

ZYSL thrust ball bearings are made to Normal tolerances as standard. Some single direction bearings with flat housing washer are also available with increased accuracy to tolerance class P6 or tolerance class P5 specifications. Contact ZYSL for availability before ordering.

Normal, P6 and P5 tolerances are in accordance with ISO 199:1997.

Misalignment

Thrust ball bearings with flat housing washers cannot accommodate any misalignment between the shaft and housing or angular misalignment between the support surfaces in the housing and on the shaft.

The bearings with sphered housing washers are generally used with sphered seat washers and can compensate for initial misalignment between the support surfaces in the housing and on the shaft

Feature of Thrust roller bearings

1. Single direction, deep-groove thrust ball bearing for applications that support heavy axial loads

in one direction

2. Open bearing for lubrication applied in place

3. Through-hardened chromium steel for durability and resistance to deformity under heavy loads

4. Pressed sheet steel retainer evenly spaces rollers for reduced friction, vibration, and noise

5. Grooved raceways for higher speeds and thrust-bearing capacity than flat washers

Application of thrust roller bearing

• thrust roller bearing Spherical roller thrust bearing’s load form a certain angle with the bearing

axis line, transfer from one raceway to another raceway. Spherical roller thrust bearings have

specially designed raceways and accommodate a large number of asymmetrical rollers. thrust roller

bearing, The rollers have an optimum conformity with the washer raceways to optimize load distribution

along the roller length. Therefore, they can accommodate relatively high speeds, heavy axial loads in

one direction and heavy radial loads. The load is transmitted between the raceways at an angle to the

bearing axis. Spherical roller thrust bearings are self-aligning and insensitive to static misalignment

of the shaft relative to the housing thrust roller bearing.
