GMN Precision Angular Contact Bearings

S DESIGN

GMN offers a broad product range in the S series in regards to dimensions, suitable RPM and load capabilities.

Standard spindle bearings
High RPM suitability and rigidity
High cost-efficiency and reliability
Standard contact angles of 15° and 25°
Reference RPM factor n x dm = 1.7 x 106 mm/min
High load rating
Also available as hybrid ball bearings

SM DESIGN

The GMN SM series offers nearly 20% higher RPMs due to its optimized internal geometry as compared to the S series.

Optimized internal ring lubrication for high RPMs
High service life due to minimized friction
High operating safety with temperature influence due to high radial bearing clearance
High radial clearance for high-speed applications
Low operating temperature due to low friction
Standard contact angles depending on internal diameter are 15°, 17° or 19°
Reference RPM factor n x dm = 2.0 x 10⁶ mm/min
Also available as hybrid ball bearings

KH DESIGN

The GMN KH series provides outstanding characteristics in regards to RPM, life expectancy and cost-effectiveness thanks to its optimized bearing geometry.

Sealed: with grease life lubrication (standard lubrication Lubcon HS Turmogrease L252 or customer-specific greasing)
Open: for oil lubrication
Optimized for highest speeds
Low operating temperature due to optimized raceway geometry
High operational safety with temperature influence due to high radial bearing clearance
Optimized ratio of the number of balls and the ball diameter to the load rating
Optimized internal geometry regarding grease space and oil lubrication
Standard contact angles are 15°, 17° and 25°
No speed reduction thanks to non-contact seals (seals are temperature-stable up to 120 °C)
No grease outlet for vertical or inclined installation position
Reduced grease desiccation due to ventilation
Saves additional sealing elements
Less sensitive to assembly site contamination
Reference speed factor n x dm = 2.1 x 106 mm/min
Also available as hybrid ball bearings
