R911325639
The R911325639 (MSK050B-0300-NN-S2-UP0-RNNN) is a top-grade synchronous servomotor supplied by Bosch Rexroth Indramat, furnished with a radial shaft sealing ring compliant to DIN 3760 - Type A standards. The radial shaft sealing ring serves as an abrasive seal, requiring a clean and adequately lubricated sealing point to minimize wear. The appliance’s radial force is reliant on the plain shaft, the effect point of the force, and the shaft load that can cause breakage. Brake failure can occur from mechanical damages, grease deficiency, or excessive wear.
The setup should only include gearboxes that are fitted with closed or oil-proof lubrication systems to prevent oil from constant contact with the shaft sealing ring. Use in high-temperature conditions is not recommended. For storage periods exceeding a year, check the electric contacts of its cables for corrosion. The protective sleeves on the motor plug connections and shaft should be detached immediately before assembly. The servomotor can be delivered globally via reliable freight carriers. It is equipped with a type plate that provides vital information for spare parts procurement and servicing. For safe handling, use suitable equipment like chain suspensions, eyebolts, and lifting sling belts. The motor is furnished with an encoder having 2048 signal periods and a keyway shaft for torque transmission in a constant direction, balanced fully with a key. Radial force increment reduces the motor’s bearing lifetime.
