GMN offers a complete range of sizes, types and designs with its spindle ball bearings in standard sizes S, SM and KH.
GMN offers high-quality and cost-efficient spindle bearing solutions for a variety of operating-related requirements on the basis of its broad offering.
GENERAL CHARACTERISTICS OF SPINDLE BALL BEARINGS
The following characteristics apply to all standard sizes as well as lubricated and separable spindle ball bearings.
Nominal contact angle 15°–25°
Forces are transferred at this contact angle from one raceway to another
Optimized for maximum RPM
Takes high radial and axial loads
These must be placed against a second bearing
Larger number of balls than with deep groove ball bearings
High rigidity and load capacity
All designs and sizes are available as hybrid bearings
All GMN ball bearings are available greased
All GMN bearing bore sizes are available with various outer diameters
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
