1.Radial and axial load capacity
Single row angular contact ball bearings of universal design have the suffix UA, UL or UO and are intended for fitting in pairs in an X, O or tandem arrangement or fitting in groups.These bearings can be fitted in any arrangement required.For tandem arrangements, pay attention to the guidelines in the section link.
The suffix UA indicates small axial internal clearance, the suffix UL indicates slight preload and the suffix UO indicates freedom from clearance in an X or O arrangementWhen ordering bearings, the total quantity of bearings must be stated, not the number of bearing pairs or bearing groups.
Bearings with the suffix 2RS have lip seals on both sides.Contact RS seals are suitable for giving protection against dust, contamination and damp atmospheres.
Bearings with lip seals on both sides are greased with a high quality grease and are lubricated for life.
Open bearings and bearings with seals on one side are not greased.They can be lubricated with grease or oil.
Open angular contact ball bearings can be used at operating temperatures from -30 °C to +150 °C.Bearings with a diameter D > 240 mm are dimensionally stable up to +200 °C.
Angular contact ball bearings with cages made from glass fibre reinforced polyamide are suitable for operating temperatures up to +120 °C, restricted by the cage material.
Sealed bearings are suitable for operating temperatures from 30 °C to +110 °C, restricted by the lubricant and the seal material.
Angular contact ball bearings with solid cages made from glass fibre reinforced polyamide have the suffix TVP or TVH.
Solid brass cages have the suffix MP.
The bearings are also available with universally applicable sheet steel window cages (suffix JP).
Check the chemical resistance of polyamide to synthetic greases and lubricants with EP additives.
Aged oil and additives in the oil can impair the operating life of plastic cages at high temperatures.
The oil change intervals must be observed.
