Angular Contact Ball B. FAG 7318 -B-XL-TVP-UA
The FAG 7318 -B-XL-TVP-UA single-row angular contact ball bearing with a 90 mm bore accommodates high radial and axial loads in one direction.
The 7318 -B-XL-TVP-UA angular contact ball bearing is an open rolling bearing made from standard bearing steel (100Cr6) with main dimensions of 90 × 190 × 43 mm. Thanks to its contact angle of 40 degrees, this design effectively distributes combined loads. An integrated polyamide cage guides the rolling elements with low vibration within a temperature range of -20 to +120 degrees. The component complies with tolerance class P0/PN or ABEC 1 and is suitable for demanding industrial applications.
What is the 7318 -B-XL-TVP-UA angular contact ball bearing suitable for in operation?
This design accommodates combined loads consisting of radial forces and single-sided axial forces. The single-row design ensures precise guidance of shafts in bearing arrangements with high rotational demands. As an open bearing, the assembly is lubricated via the housing design, using either grease or lubricating oil. Low rolling resistance helps to ensure smooth running characteristics during continuous operation.
What does the UA design mean in a paired arrangement?
The UA designation identifies this angular contact ball bearing as a universal bearing for installation in pairs. When two bearings are mounted in an O or X arrangement, a defined, low axial clearance is achieved without the need for shims. The O arrangement absorbs tilting moments, whilst the X arrangement compensates for minor misalignments. Correct alignment of the wide and narrow shoulders is essential for proper operation.
What are the dimensions of the 7318 -B-XL-TVP-UA angular contact ball bearing?
The bearing has an inside diameter of 90 mm, an outside diameter of 190 mm and a width of 43 mm. The outer ring is cylindrical in design and has neither a flange nor a ring groove. These standardised dimensions allow for direct replacement in standardised housings and bearing seats.
What is the purpose of the 40-degree pressure angle?
The contact angle describes the line of action between the raceways and the rolling elements relative to the radial plane. An angle of 40 degrees enables the component to absorb particularly high axial forces in one direction. The reaction forces specifically support the radial and axial load components during operation.
What does the code letter ‘TVP’ on the cage mean?
The suffix ‘TVP’ denotes a polyamide cage. This material is characterised by its low weight, elastic properties and effective vibration damping. The cage operates quietly and is designed for an operating temperature range of -20 to +120 degrees.
How is the 7318 open angular contact ball bearing lubricated?
As this model is supplied without integrated sealing washers, you should select the lubricant to suit the surrounding structure. The bearing can be lubricated via the housing design using roller bearing grease or in an oil bath. The open design allows for unimpeded lubricant circulation, ensuring continuous heat dissipation.
Why is the UA marking important for installation in pairs?
Bearings with the UA designation are designed by the manufacturer to be compatible with one another, meaning they can be paired without the need for further machining. When two bearings are fitted in an O or X configuration, a small amount of axial clearance results due to the design. This facilitates assembly and promotes even load distribution within the bearing set.
What is the tolerance class of the 7318 -B-XL-TVP-UA angular contact ball bearing?
This roller bearing is manufactured to the standard tolerance P0 or PN, which corresponds to the ABEC 1 classification. This standard precision meets the requirements of general mechanical and plant engineering. The dimensional and running tolerances ensure a good fit on cylindrical shafts and in standard housings.
