Bearings For Siemens Motors | PDF | Manufactured Goods
The document contains specifications for Siemens motors including bearing types, frame sizes, and shaft sizes. It lists the bearing types, frame sizes, and tapped shaft hole sizes for various motor types including 1LA7, 1LA2, 1LA6, and 1LG4 or 1LG6. The shaft diameters range from 9mm to 80mm depending on the motor type and frame size.
Select the frame size and therefore the possible motors on the basis of the following parameters: cooling method, degree of protection, rated power, rated speed and rated torque range. Note: The standard temperature range of the motors is from -20 to +40 °C.
Many of the parts that NTN supplies to SIEMENS include special, non-standard features specifically designed for SIEMENS motor model 1PH7/1PA6. These compact asynchronous motors supplement the synchronous servo motors for applications in the upper power range up to 630 kW (845 HP).
The bearings of totally enclosed fan–cooled (TEFC) motors from frame size 315 and the internally cooled open–drip proof (ODP) motors from frame size 250 are equipped with regreasing devices and automatic grease quantity control.
Motors having roller bearings require a minimum radial load. Use of these motors in direct connected applications is discour-aged to avoid excessive drive end bearing noise and/or reduced bearing life. Stick-type are available for anti-friction bearings. Available for 449 frame and standard on all other frames.
diverse range of frame sizes. Sleeve Bearings Split sleeve bearings are typically standard on motors with larger frames and higher speeds, and optional for most others. • Tin-based babbitt Iiners are bonded to bearing bushing shells. • A large lubricant reservoir provides self …
Optimized bearing systems have been developed to ensure safe, fault-free operation of the motors when they are subjected to the combined effects of vibration and shocks. The motors are equipped as standard with bearings of series 63. The bearing at the drive en d (DE) is always a located bearing, while the bearing arrangement is preloaded at the
