The Brief Description of Angular Contact Ball Bearings:
Angular contact ball bearings are the most representive of the rolling bearings,a wide range of uses.for speed operation,but also very durable,without regular maintenance.small coefficient of friction of such bearings ,limit high-speed,simple structure,low mannufactringcost and easy to reach a higher manufacturing precision.
Lubrication
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.
Operating temperature
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.
Cages
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.
