Introduction:

 

 

ZYSL thrust ball bearings are produced as single direction or double direction thrust ball bearings. They are designed to accommodate axial loads only and must not be subjected to any radial load. 
ZYSL thrust ball bearings are separable, i.e. the shaft washer, housing washer(s), ball and cage assembly(s) can be mounted separately. Shaft washers have a ground bore to enable an interference fit. The bore of the housing washer is turned and always larger than the shaft washer bore.

Single direction thrust ball bearings

 

Single direction thrust ball bearing

ZYSL single direction thrust ball bearings consist of a shaft washer, a housing washer and a ball and cage assembly (fig 1). As their name implies, single direction thrust ball bearings can accommodate axial loads and locate a shaft axially, in one direction only.

 

 

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

Descriptions

Single direction thrust ball bearings have two washers, with grooved raceways. 

The curvature of the raceways is slightly larger 

than that of the ball. Out of two washers, one is shaft washer & the other one

is housing washer.  

The bore of the shaft washer isof the shaft dia & the bore of the housing washer

is slightly larger than that of shaft washer, to facilitate free rotation. These types 

of thrust bearings are mainly used where axial load conditions are too large to be 

accepted by radial bearings. They canaccept purely thrust load in single direction 

& they are not suitable for speed applications.

Single direction thrust ball bearings: consist of two washers with raceways and balls guided b a

cage. Washers have flat seating surfaces, and that is why they must be supported so that all balls

can be evenly loaded. Bearings carry the axial load only in one direction. They are not able to carry

radial forces.

Double direction thrust ball bearings: have two cages with balls between the central shaft washer

and two houding washers with flat seating surfaces. The shaft washer has raceways on both sides

and is fixed on the journal. Bearings are able to carry only axial forces in both directions.

These bearing are widely used in automobile, electrical. (Home appliances, electric tools, fitness

equipment, motors, medical devices, motorbikes, textile machines)
