PS Thrust Bearings

The PS Thrust Bearing design is attached to a given clamping surface using four socket head cap screws. Four M6x15 are supplied with each assembly to attach the cap to the base. The PS Thrust Bearing design allows for a housing washer of a thrust bearing to be mounted with ease, while maintaining a separable design with regard to the shaft washer while offering angular slew of up to 5°.


PS Thrust Bearing Capacity Table 

  • Attachment Cap Bolts 


Breaking loads shown above can be approached by using UNBRAKO High Tensile Cap Screws. Attachment bolt and cap bolt loadings and capacity should be determined independently. This is to account for different bolt types and different surface conditions with regard to the clamping surface. 

  • Housing Materials


The values in the Static Breaking Load Capacity for PSB Eyeball Housings (kN) Table are for a PSB Eyeball Housing made from zinc plated bright mild steel. Housings can be made from aluminium, bronze, stainless steel, zinc plated bright mild steel and a variety of plastics such as UHMWPU to suit a range of environmental conditions. Note that by selecting a material which is not zinc plated bright mild steel, the static load capacities in the table above do not apply. 

  • Special Purpose Housings on Request


Special purpose housings can be supplied on request. We can accommodate bearings of different size, load rating, and angle of slew. Please use the enquiry form on the website or send a request to with the specifications of the desired bearing, as well as any special purpose requirements, such as a preferred housing material, environmental conditions, or required heavy load capacity. 

  • Suitable Bearings for PS Thrust Bearing Housings


The bearing series suitable for use in PS Thrust Bearing Housings is the GX F series. These bearings are available for 20, 30, and 40mm shaft size PS Thrust Bearing Housings.
