Each spindle assembly is defined by the model number, which consists of a maximum of seven code symbols.
Cartridge and block spindles are identified by the first five code symbols. The first symbol determines the size of the spindle. The second symbol identifies the cartridge mounting or block configuration. The third symbol identifies the internal construction type and the fourth identifies the nose end bearing preload. The fifth symbol identifies the type of spindle nose.
Specify speed when ordering. Brackets are available for all cartridge spindles, see dimension sheets in Catalog 606D (4.18 MB) for model numbers.
Motorized Spindles use the first five code symbols of the cartridge assembly, and the sixth code symbol to describe the type of motor drive.
On most belt-drive units, the motor can be positioned at four locations around the spindle (see drawing at right), but motor positions are not field changeable. Position “A” will be furnished unless otherwise specified. Motor dimensions and frame size may vary.
If exact dimensions are required, request certified print. Specify spindle speed when ordering. All motors will be supplied 230/460 volt, 3-phase 60 cycle. Consult factory for other motor specifications and spindle speeds not shown in charts.
°1250 Arbor nose not available.
+B1 available in 6500 vertical travel motorized spindle.
‡Medium preload is offered as standard. Light and heavy preloads are available upon request. 1250 and 1875 only available with medium preload.
Motorized vertical travel spindles use all seven code symbols. The last symbol identifies the slide drive. All vertical travel belt-drive units use the B1 belt-drive in Position “A”.
You can readily determine the spindle model number as you decide on size, cartridge mounting, internal construction, shaft type and if motorized or vertical travel drives are required.
Check to see that each code symbol in the model number is indicated under the size selected and to the left in the column under the assembly selected. These are the spindle assemblies that are available.
We can give prompt accurate service if complete information is provided with the order. If you have any questions, please phone our Sales Engineering Department at (262) 377-2434.
Specify air purge if required. Fittings will be supplied upon request on nose end of cartridge spindles and each end of block spindles.
The engineering department of SKF Precision Technologies reserves the right to change specifications without notice. Do not base final decisions on catalog drawings - ask for a certified print when you order a spindle.
If servicing should be required on any Gilman spindle, we suggest the unit be returned for factory service to assure optimum performance and life.
