Speed values are reference data under the manufacturer’s stated test and lubrication conditions. Permissible operating speed must be checked for the actual spindle arrangement, preload, lubrication, temperature and load.
Designation guide
-
E: 25° contact angle.
-
DLR: direct lubrication arrangement with integral O-ring provision.
-
T: outer-ring-guided textile laminated phenolic resin cage.
-
P4S: super-precision dimensional and running-accuracy class.
-
UL: universal matching with light preload in a paired arrangement.
Application and ordering
The hybrid construction supports high-speed spindle operation with reduced frictional heat and wear compared with an otherwise comparable all-steel design. Typical applications include precision machine-tool spindles and grinding spindles requiring high running accuracy and rigidity.
Before ordering, confirm the complete designation, quantity, bearing arrangement, lubrication method, spindle or machine model and delivery location. SGU Precision confirms current price, availability and source by quotation.
Technical information is provided for product identification. Final suitability and current manufacturer data should be confirmed during engineering review and quotation.
