NIBC’s 60° precision angular contact ball bearings are used for machine tools or machines requiring the highest levels of precision, speed, rigidity and lower levels of friction. NIBC's Ball Screw Support Bearings are easy to assemble, have increased bearing life, the option of lifetime lubrication or circulating oil lubrication, as sometimes employed for driven ball screw nuts are other features which should be adjusted to match each other optimally. Next to the open 60° bearings, several sizes are manufactured with a non-contact rubber seal at both ends.
Angular Contact Ball Bearings with small contact angles of 15°, 25° mainly absorb radial loads and only qualify for low axial loads.
The ratio is different in case of 60° super precision angular contact thrust ball bearings because the axial load is to be predominated here.
Depending on the required rotational speeds and rigidity, it is possible to choose between light, medium and heavy preload.
The units are available as standard, duplex and quadruplex units with lifetime lubrication in open and sealed variants.
NIBC bearings also available in sealed variants as an option.
Some of the advantages of the NIBC Ball Screw Support bearings include
1 High Axial Rigidity
Greater number of balls with polyamide cage provides increased rigidity
2 Compact Design
3. Low Noise
Due to high quality of surface roughness achieved on the races combined with polyamide cage allows the bearings to have a Low Noise.
4 Ease of Assembly
5 Pre packed grease
